Looking for an online college bookstore business plan? You're in the right place.
A textbook business has to answer questions that a bank or an investor will ask before it ever sees a customer. How much stock do you buy before the first term, and who pays for it? What does it cost to mail a book to a student and get it back? How many months of the year does the business lose money? A generic template won't tell you what a believable answer looks like.
In this article we'll go through a complete sample business plan for a textbook rental, resale and marketplace business in Indianapolis, Indiana, section by section. You'll see the executive summary, a SWOT-style look at strengths and exposures and, in the most detail, the financials, with stock on the balance sheet and a seasonal cash table.
What you'll take from it:
- The executive summary: see how to fit the offer, the funding request and the first three years onto one page
- The unit economics: work out what a single rental or resale costs to deliver, so the margin comes from postage, packaging and book cost
- The warehouse and book cycle: learn how stock, returns and handling hours fit together, and what to say about editions that go out of date
- The first year, month by month: find the quiet months before you reach them, and plan cash around August and January
- The marketing plan: see what a campus-focused store might spend to win its first 2,000 or so customers, and which channels carry the load
- Five years of profit and loss, cash flow and balance sheet, with an inventory line: understand how stock turns and seasonal peaks show up in every table
- The downside case: have an answer ready for "what if sales run 20% short?", with the steps the founder takes in response and a table of single-input shocks
The company is fictional. A textbook or used-book business can take the parts that fit its market and replace the rest.

Executive Summary
Blue Spine Textbooks is an Indiana online bookstore that opens in Indianapolis on January 1, 2027, in time for the spring term. It rents textbooks by the semester, sells used copies and runs a marketplace where students sell to each other for a 12% fee. Founder Marcus Okafor holds 55% of the company, and two local investors hold 45%.
The business raises $670,000: $120,000 from Marcus, $500,000 from the investors and a $50,000 bank term loan. A $150,000 seasonal line of credit from the same bank sits alongside it from January 2028. Of the $670,000, $525,700 stays in the bank as a reserve, $60,000 buys the opening stock of about 1,450 books, $16,000 buys shelving and equipment, and $68,300 pays for the platform build, legal work, licenses and the launch.
| Year 1 | Year 2 | Year 3 | |
|---|---|---|---|
| Revenue | $495,520 | $879,249 | $1,275,945 |
| Net income after start-up costs | ($123,166) | $7,150 | $41,351 |
| Closing cash | $402,441 | $353,290 | $335,919 |
In 2027 the store ships 8,150 books, 6,400 of them rentals, and the marketplace completes 1,200 sales between students. The year loses money because orders bunch into a few weeks. August alone is 31% of annual revenue, nine months of the year show an operating loss, and stock has to be bought before it sells. Year 2 is profitable by a small margin ($7,150), and the margins stay thin: EBITDA is 3.7% of revenue in Year 3 and 8.2% in Year 5.
Two cash figures matter more than the year-end closes. Year-end cash stays above $329,000 in every year, but the July low is far lower: about $337,000 in Year 1, about $2,000 in Year 4 and about $22,000 below zero in Year 5 before any borrowing, because the business pays for stock and payroll through the spring and summer and collects in August. The reserve carries the July low through Year 3 without borrowing, and the $150,000 seasonal line holds month-end cash at $50,000 in Years 4 and 5. The July figures are estimates built from the model's annual totals.
The business tests itself. If revenue runs 20% below forecast and Marcus acts on it, with a pay cut from month 9, a smaller marketing budget and fewer agency workers from Year 2, late hires, no last hire and no distribution, year-end cash stays positive in every year, with a low of $252,885 in Year 4, and the seasonal line peaks at about $90,000. Single shocks show how thin the margins are: a 10% revenue shortfall with no response, or a rental price $5 lower, loses money in Years 1 to 4.
The pitch is narrow. A student can rent, buy used or buy from another student on one site, the return label is in the box, and prices start from what each book costs to deliver.

Goals for 2027 and 2028
- Ship 8,150 books in 2027 (6,400 rentals and 1,750 used copies) and complete 1,200 marketplace sales.
- Reach $879,249 of revenue in 2028, the first year with two full terms of repeat customers.
- Lose or write off fewer than 3.5% of rental copies in each year.
- Reach a profit after tax in 2028 and keep the July cash low inside the reserve plus the $150,000 line in every year.
The Indianapolis Textbook Market
A shrinking pool of book spending
The College Board's 2025 Trends in College Pricing report cites independent research from Student Watch and Student Monitor showing a 40% to 54% fall in average student spending on college textbooks and digital course materials over the last ten years. That is the central fact about this market. Students spend less per head, they compare prices before they buy, and a business that depends on volume has to keep its cost per book low.
The Indianapolis area has several campuses: IU Indianapolis, Butler University, the University of Indianapolis, Marian University and Ivy Tech Community College among them. No enrollment figure is quoted here, because each school publishes its own, and a lender would divide the 2,090 Year 1 store customers by the published enrollment of the schools served to test the share. Blue Spine ships nationally, so its customers are not limited to these schools, but the first campaigns are aimed at them.
Who else sells the same book
| Alternative | What it offers | Why a student uses it | Where Blue Spine differs |
|---|---|---|---|
| Campus bookstores | Course lists, new copies and returns on campus | Convenience, and the book is certain to match the course | Rental and used copies delivered to the dorm, with a marketplace for selling back |
| National online rental sites | Large catalogs and national shipping | Breadth of titles | A local team, campus ambassadors and a marketplace |
| General online marketplaces | Every kind of seller and condition | Price and speed | Books only, with condition grading and course-list search |
| Publisher digital access | Electronic copies, sometimes bundled into fees | No shipping | Print for students whose courses or habits still call for it |
| Libraries, reserves and open textbooks | Free or low-cost access | Zero cost | Owned copies for the whole term |
The table describes categories and Blue Spine's position, not a ranking. Prices and terms change often, and no competitor's prices are quoted here. Blue Spine has not benchmarked its prices against any campus store.
Strengths and exposures
Strengths. A founder who bought used and rental stock for a campus bookstore group for eight years. A cost model built from postage and book cost. Ordering that matches how students buy. Stock bought for cash, so no vendor owns the shelves.
Exposures. No brand on any campus at opening. A stock position bought ahead of each term that loses value if a professor changes the book. Three months that carry 64% of revenue. One senior person in the business for most of Year 1. A marketplace that needs buyers and sellers on both sides before it earns much.
Openings. Students looking for a cheaper way to get required books. Campus ambassadors as a low-cost channel. A marketplace that grows with every listing and costs little to serve once it has buyers.
Threats. Falling spend per student. Courses that move to digital materials, which may be bundled into fees at some schools. Larger sellers cutting rental prices for the August rush. Postage rises.
The Student Customer
Three kinds of buyer use the store. The renter is a full-time undergraduate who takes two or three titles a term from Blue Spine, leaves the rest to the campus store or the library, and gives the books back. The saver wants to keep a book, usually for a sequence of courses or a reference shelf, and buys used. The seller is a student who has finished a course and would rather list the book than carry it to a campus buyback desk.
Most decisions are made in the three weeks before a term and the first two weeks of it. A student starts from the course syllabus, searches by ISBN or title and compares the rent price with the used price. The cost of getting it wrong is real: a wrong edition is a wasted order, and a late book is a missed week. The store therefore leads with the ISBN match, shows the condition grade and gives an estimated delivery window before payment.
The Year 1 forecast has about 2,090 store customers placing orders of 2.6 books. That is 3.9 books and 1.5 orders each in the year, which means about half the customers return for a second term. A customer who rents in August often rents again in January, which is why Year 2 revenue grows 77%. A further 800 or so marketplace-only buyers and sellers bring the user base to about 2,900.
Rent, Buy or Sell: The Offer
How prices are set
Prices start from cost. Each offer has a per-book cost that the price must cover with a margin. The table shows the rental as the model uses it, and the used sale and marketplace sale follow it.
| Cost of one rental at $50 | Amount |
|---|---|
| Media Mail postage out and back (about $6.00 a leg) | $12.00 |
| Payment processing | $1.75 |
| Packaging and label | $0.65 |
| Copy cost used up ($40 bought, $10 resale value, four rentals) | $7.50 |
| Damage and non-return loss | $1.60 |
| Total | $23.50 (47%) |
The USPS Notice 123 single-piece Media Mail price, effective October 4, 2026, is $5.86 for a package up to 3 lb, $6.60 up to 4 lb and $7.34 up to 5 lb. Titles pack at different weights, so the model uses $6.00 a leg as a planning average. Media Mail is a rate for qualifying material such as books, and eligibility, current prices and any carrier discount should be confirmed with USPS. Media Mail takes several days, so the checkout shows an estimated delivery window, with a faster service, paid for by the student, offered in the first week of each term. A copy must be rented four times before its cost is used up.
The rental sits at 57% of the used price. A student could instead buy used at $88 and resell the book on the marketplace at its average of about $52. After the 12% fee and about $6 of postage that route returns about $40 and nets out near $48 for the term, within a few dollars of the $50 rental. The rental carries no resale risk, no edition risk and no listing work, and that is what the extra $2 pays for. The gap is small, so competitors' rental prices set the ceiling, and the sensitivity table tests the rental price harder than any other input.
A used sale at $88 costs $54.56 (62%): $42.00 for the book, $6.00 of postage, $2.65 of payment processing, $0.65 of packaging and $3.26 for refunds and returns. The $42.00 is a planning average delivered to the warehouse, inbound freight included; for a buyback copy that resells at $88 it equals a quote of about $36 plus about $6 for the prepaid inbound label. A marketplace sale of about $52 earns a $6.20 fee and costs $1.98 (32%) in processing and disputes. A damage waiver at $4.00 costs $2.00 in claims.
An order from search to return
- The student searches by ISBN, title or course.
- The page shows rent, buy used and marketplace listings side by side with condition and an estimated delivery window.
- Payment is taken at checkout through a hosted card form.
- The warehouse picks, checks and packs the book the same day, and ships it by Media Mail or the faster option.
- For a rental, the due date is two weeks after the term ends, and an email and a text message arrive five days before.
- The student returns the book in the prepaid label. The warehouse inspects it, grades it and shelves it for the next term.
- A late fee of $1 a day runs for 14 days after the due date, and a book still out after that is billed at its replacement price.
Marketplace sales follow steps 1 to 3, then the seller ships with a label bought at checkout, and payment is released when delivery is confirmed.
Getting Found by Students
What marketing buys
The Year 1 budget is $54,000: $12,000 of launch spend paid from start-up funds and $42,000 of running costs. That is 10.9% of Year 1 revenue with the launch spend, and the running budget falls to 5.5% of revenue by Year 3 and 5.3% by Year 5 as returning customers carry more of the load. Spread over about 2,090 store customers, Year 1 costs about $26 each, and about $19 over all 2,900 users. Each store customer brings in about $113 of gross profit in the year, so the cost comes back within the first year.
| Channel | Year 1 spend | Expected new users |
|---|---|---|
| Paid search and shopping ads, aimed at ISBN searches | $11,000 | 625 store customers |
| Campus ambassadors (commission and stipend) | $8,000 | 520 store customers |
| Semester-start tabling, flyers and orientation events | $4,500 | 270 store customers |
| Social posts and short video | $4,500 | 250 store customers |
| Referral credits for existing customers | $4,000 | 250 store customers |
| Email and text reminders | $2,000 | 175 store customers |
| Marketplace seller campaigns (end-of-term listing prompts, payout credits) | $4,000 | 800 marketplace-only users |
| Faculty and department outreach | $1,500 | |
| ISBN landing pages and seasonal content | $2,500 | |
| Launch: brand and photography | $2,500 | |
| Launch: course-list landing pages | $3,500 | |
| Launch: ambassador recruitment and kit | $2,500 | |
| Launch: first-order credits | $3,500 |
Faculty outreach, landing pages and the launch items bring customers in through the channels above them, so they carry no count of their own. Marketplace support and dispute handling sit in payroll and in the 32% cost of a marketplace fee.
Marketing milestones
- January 2027: storefront live, ambassadors in place at three campuses.
- April 2027: first end-of-term seller campaign.
- August 2027: peak month handled with agency staff, with about 2,550 books shipped.
- December 2027: spring pre-order campaign, about 2,090 store customers on the list and 1,200 marketplace sales for the year.
The Warehouse and the Book Cycle
The flex unit
The unit is 2,800 square feet at about $9.65 a square foot a year including common-area charges ($27,000 in Year 1), a planning figure to be checked against current Indianapolis listings, with a loading door, racking and a pack bench area. Stock is shelved by title and condition grade. The business moves to 3,800 square feet in Year 4 when the library outgrows the first unit.
Where the stock comes from
Opening stock is $60,000, about 1,450 books, a mix of rental copies and used copies for sale. That covers the spring term, when about 1,150 books ship between January and March. After that, copies arrive from three places: end-of-term returns from rentals, student sellers who send books in for a quoted price, and used-book wholesalers. Buyback quotes are set from wholesale market prices, run at roughly 40% of the expected resale price for a title in current use, and fall to nothing for a title with a new edition due.
Editions are the main risk. A publisher can issue a new edition at any time and a professor can change the required book, so a copy in stock can lose most of its value in one term. The budget for write-downs is $7,000 in Year 1 and $26,000 by Year 5, about 7% to 9% of average stock at cost. Heavier losses in a bad edition year would come out of the reserve: at three times the budget, Year 3 profit falls from $41,351 to $9,351 (see the sensitivity table). The business buys deep only for titles with a track record, and checks course lists each December and May.
The rental library is sized to the fall rush. A copy can go to only one student a term, and 59.5% of a year's rentals ship between July and November, so the library holds one copy for each of those rentals plus 5%. Each copy is then rented about 1.6 times a year and reaches its fourth rental in about two and a half years. The last two rows below check the balance-sheet stock against that: stock per fall copy should sit between a new copy's $40 and a worn one's $10, and book cost used up divided by year-end stock gives the turn. Direct costs also include postage and card fees, so dividing them by stock would overstate the turn.
| Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | |
|---|---|---|---|---|---|
| Rentals shipped July to November | 3,808 | 6,545 | 9,223 | 11,424 | 13,388 |
| Rental copies for the fall rush (plus 5%) | 3,998 | 6,872 | 9,684 | 11,995 | 14,057 |
| Year-end stock at cost, rental and used | $123,825 | $173,251 | $224,347 | $270,663 | $314,742 |
| Stock per fall copy | $31 | $25 | $23 | $23 | $22 |
| Stock turns on book cost used | 1.0 | 1.2 | 1.3 | 1.3 | 1.3 |
Shipping, returns and handling hours
Outbound orders ship on the day they are packed. Rentals carry a prepaid label for the return. Handling is set at 6 minutes per book shipped, 5 minutes per rental returned and 4 minutes per book received. Books received are the book cost used up plus the year's stock growth, divided by the $41 average cost of a book. Returns follow the term calendar: fall rentals (shipped July to November) come back 40% in December and 60% in January, spring rentals (December to April) in May and June, and summer rentals in August. Paid productive hours are 1,600 a year for each employee (133 a month, after leave, training and non-handling work) and 150 for each agency person-month. Months take their shares from the 2027 monthly table in every year. Marcus's own warehouse time is not counted and is the cushion in the busiest weeks.
| Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | |
|---|---|---|---|---|---|
| Books shipped | 8,150 | 13,950 | 19,550 | 24,150 | 28,100 |
| Rentals returned in the year | 2,963 | 8,530 | 13,084 | 17,213 | 20,728 |
| Books received | 4,520 | 6,240 | 8,230 | 9,713 | 10,928 |
| Handling hours needed in the year | 1,363 | 2,522 | 3,594 | 4,497 | 5,266 |
| Paid productive hours in the year | 2,500 | 4,267 | 6,033 | 7,950 | 8,650 |
| Busiest month, hours needed as a share of paid hours | June 80% | December 87% | January 83% | December 75% | May 86% |
| August hours needed and paid | 319 and 433 | 546 and 717 | 765 and 1,000 | 945 and 1,283 | 1,099 and 1,433 |
Annual demand is 55% to 61% of paid hours. Year 1 returns are low because the fall rentals come back in January 2028. Until the first associate starts in month 14, the receiving lead and the agency workers supply the counted hours in Year 1, with Marcus as the cushion. Hours needed run from 17% of the lead's paid hours in April to 80% in June, when the stock for the fall term arrives, and agency workers are booked in July (1), August (2), September (1) and December (2). August runs at 74% to 77% of paid hours in every year because it is staffed first. The tightest later months are July (85%) and December (87%) of Year 2, January of Year 3 (83%) and May of Year 5 (86%), which the founder covers. Agency person-months rise from 6 in Year 1 to 15 in Year 5, at a bill rate of $26 an hour.
Systems and the order platform
A hosted storefront with custom rental logic, due dates and return labels. A seller account system with payouts held until delivery. A book-data feed for ISBN lookups and a pricing tool. Shipping-label software, a help desk and fraud screening. The platform build is $48,000, software costs $15,000 in Year 1 and $26,000 by Year 5, and a contract developer on a retainer keeps the platform running ($5,000 in Year 1, $14,000 in Year 2).
Rules the business has to meet
- Sales tax. The Indiana Department of Revenue gives the sales tax rate as 7% on the purchase or rental of tangible personal property, so rentals are taxed as well as sales, and the tax collected is passed on and is not revenue. Businesses that sell goods must register, with a Registered Retail Merchant Certificate for each retail location. The registration page also lists facilitating sales of tangible personal property as an activity that can need extra registration, so the business confirms its marketplace duties with the Department and its accountant before the marketplace opens.
- Other states. Shipping nationally can create a duty to collect sales tax in states where sales pass a threshold. The thresholds vary by state, and the business checks them each quarter and registers where needed.
- Seller payouts. Holding seller money until delivery can raise money-transmission questions. Payouts run through a payment processor's marketplace product, and counsel confirms the structure before launch.
- Resale of owned copies. Under 17 U.S.C. 109(a), the owner of a lawfully made copy may sell or dispose of it without the copyright owner's authority. The business buys through documented channels and checks ISBNs to avoid counterfeit copies.
- Rental terms. The rental agreement, grace period, late fee, replacement charge and damage waiver are drafted by a lawyer as part of the $7,500 legal budget.
- Insurance. General and product liability, cyber, stock and equipment, and key-person cover on Marcus, budgeted at $9,000 in Year 1; workers' compensation sits in the 27% payroll load.
Vendors and advisers
Carriers, the platform vendors, a payment processor and used-book wholesalers. None is hard to replace. A former campus store director reviews the buying plan each quarter.
Who Runs It
Marcus Okafor, founder and operations lead
Marcus spent eight years as a course-materials buyer for a campus bookstore group in the Midwest, setting rental and used quantities for each term and learning how often a quantity was wrong. He then spent three years running fulfillment at an online book distributor. He holds an undergraduate degree in business. His $120,000 is eight years of savings, and he draws $66,000 in salary, below what his last job paid.
Where the team is thin
Marcus has not built a marketplace or a paid-search campaign from nothing. Those gaps are covered by a contract developer on retainer, an ambassador program paid by commission and stipend, and a marketing coordinator hired in month 32.
If Marcus is out
Pricing and buying rest with Marcus. Until a second person can do it, the receiving lead is trained in buying from Year 2, buying decisions go through a written routine, and the adviser reviews them each quarter. The receiving lead can also run the warehouse, and the support coordinator can run customer service. The business carries key-person life and disability cover on Marcus. None of the fulfillment associates hired later has a buying role.
Owners and the bank
Marcus owns 55% of Blue Spine Textbooks, LLC and the two local investors own 45%. The investors have information rights and a seat on a monthly review call. Their $500,000 implies a value of about $1.1 million after the investment; Marcus's larger share reflects the unpaid pre-launch work and his buying and fulfillment record, on top of his $120,000, and the split is a negotiated figure. The investors' share of Year 5 net income of $118,027 is $53,112, or 10.6% of what they put in, against a cash share of $22,500 from the $50,000 Year 5 distribution. Any return beyond that depends on a later sale or buyback, which this plan does not forecast; the investor agreement would set out any redemption terms.
What a lender would still ask
- Seasonal line. The July estimate is the figure to read, and the table in the cash section sets it out. The $150,000 line from the same bank covers the largest downside draw ($90,000 in Year 5) with $60,000 to spare, but the Year 5 draws are 23% of year-end stock at cost in the base case and 34% in the downside. The bank's advance rate on used and rental stock decides how much of the line is available, a lower rate means more cash held by the owners, and the line has to clear to zero each year from the August and September receipts.
- Collateral. Stock and equipment total $76,000 at opening against a $50,000 loan, and the stock is exposed to edition changes, so the lender also takes Marcus's personal guarantee and a lien on stock for the line.
- Debt cover. Cover is negative in Year 1 and 1.3x in Year 2, and the downside is under 1.25x in Years 1, 2 and 4. The ask is no test on Years 1 and 2, a 1.25x test from Year 3 results and a $300,000 liquidity test as the alternative.
- Rental price and repeat rate. A rental price of $45 instead of $50 loses money in Years 1 to 4, so the lender would want competitors' current rental prices for the titles that make up most volume. The forecast has 1.5 orders per customer in Year 1; share of enrollment is not stated, because no enrollment figure is sourced here.
- Lease, platform and key person. The unit is on a draft lease, and the term, the option to move to 3,800 square feet in Year 4, the deposit and Marcus's guarantee are open points. The $48,000 platform build needs two written quotes and company ownership of the code. Pricing and buying rest with Marcus until a second person is trained.
- Marketplace controls. Payouts are released on delivery confirmation, disputes are handled by the support team, and sales tax and payout questions are settled with the accountant and counsel before the marketplace opens.
Financial Plan: Stock, Shipping and Semesters
Blue Spine runs on one five-year model, monthly through 2027 and by year after that. The book-trade items come first: opening stock, what it costs to get a book to a student and back, and the way orders bunch around the start of each term. The annual tables hide a deep mid-year dip, so the cash section adds a July table.
Start-up funding and opening stock
| Use of funds | Amount |
|---|---|
| Opening stock: rental library and used-book inventory | $60,000 |
| Shelving, scanners, label printers, pack benches, workstations | $16,000 |
| Sales-tax registration and business licenses | $800 |
| Legal: entity, seller terms, rental agreement, privacy policy | $7,500 |
| Platform build: storefront, rental logic, seller accounts, payments | $48,000 |
| Launch: brand, ISBN pages, campus ambassadors, launch credits | $12,000 |
| Cash reserve for stock build-ups, the summer trough and the loss-making first year | $525,700 |
| Total uses | $670,000 |
| Source of funds | Amount |
|---|---|
| Marcus Okafor's savings | $120,000 |
| Two local investors (minority stake) | $500,000 |
| Bank term loan | $50,000 |
| Total sources | $670,000 |
Marcus puts in $120,000 and two local investors put in $500,000 for a 45% stake, which leaves Marcus with 55%. The investors' price implies a company value of about $1.1 million after the investment; Marcus's larger share reflects the unpaid pre-launch work and the buying and fulfillment experience he brings, and the split is a negotiated figure. A $50,000 bank term loan runs seven years at 10.25%, interest-only for the first six months, secured on stock and equipment with Marcus's personal guarantee. The rate is an illustration, not a quoted lending rate, and the loan is sized to what Year 2 cash flow can service (cover of 1.3x). Stock and equipment cost $76,000 at opening, so the loan is covered on paper, but a superseded edition loses most of its value, so the lender would look to the guarantee as well. Of the $670,000 raised, $525,700 is held back as a reserve. The reserve carries the July low without borrowing through Year 3; in Years 4 and 5 a $150,000 seasonal line of credit from the same bank keeps month-end cash above $50,000. The line is available from January 2028, is drawn only for the weeks around the August rush and is cleared out of the fall receipts. It is not in the annual tables because it is repaid inside each year; its commitment fee and interest are in the P&L.
Operating figures behind the model
- Rentals average $50 a book for one semester, across paperbacks at the low end and science texts at the high end. Used copies sell for an average of $88, so a rental costs 57% of a used copy. A student who buys used at $88 and resells on the marketplace at its average of about $52 recovers about $40 after the 12% fee and about $6 of postage, so that route nets out near $48 against the $50 rental. The two come within a few dollars of each other, which makes the rental price the input most exposed to competition; the sensitivity table has a $45 case. A marketplace sale averages about $52 and the 12% fee rounds to $6.20. The damage waiver costs $4.00 a rented book and 55% of rented books carry it. All prices rise 3% a year from Year 2.
- Year 1 volume is 6,400 rentals, 1,750 used copies sold and 1,200 marketplace sales. By Year 5 that becomes 22,500 rentals, 5,600 used copies and 14,500 marketplace sales. About 2,090 store customers place the Year 1 orders at 2.6 books an order, which is 3.9 books each and 1.5 orders each, so about half return within the year. Another 800 or so marketplace-only buyers and sellers join them. Each store customer brings in about $113 of gross profit.
- Orders follow the academic calendar. In Year 1, August carries 32% of rentals, December 18%, September 14%, January 6% and April 2%. January is a soft launch in the first weeks of the spring term, and December carries pre-orders for the spring term. Marketplace sales follow the same shape and start slowly while the first sellers list their books. Years 2 to 5 are shown as annual totals and reuse the 2027 monthly shape; if spring orders arrived in January instead of December, year-end balances would be lower by the amount moved and the July balances would not change.
- A rental costs $23.50 to deliver on a $50 price, or 47%: $12.00 of Media Mail postage out and back, $1.75 of payment processing, $0.65 of packaging, $7.50 of the copy's cost used up (bought at $40, worth $10 after four rentals) and $1.60 of damage and non-return loss. The $1.60 is a planning figure equal to about three copies in a hundred lost or ruined, at a net cost near $53 each after replacement charges collected. A rental is due two weeks after the term ends, a late fee of $1 a day runs for 14 days, and after that the replacement price is billed; the model books no late-fee income. A used sale costs 62% of its price, a marketplace fee 32% and a damage waiver 50%. Together these give a direct-cost rate of 51.5% in Year 1.
- Postage uses $6.00 a leg. The USPS Notice 123 single-piece Media Mail price effective October 4, 2026 is $5.86 up to 3 lb, $6.60 up to 4 lb and $7.34 up to 5 lb. Titles pack at different weights, so $6.00 is a planning average between the 3 lb and 4 lb prices. Prices change, and a commercial carrier contract could be lower; the sensitivity table has a case at $6.60 a leg.
- The model holds the Year 1 direct-cost rate in every later year. Marketplace fees, the cheapest revenue to earn, grow from 1.5% to 5.1% of revenue, so later margins are slightly cautious. Without the marketplace line, and with staffing unchanged, Year 5 EBITDA would be $107,160, or 5.7% of the remaining revenue.
- Stock is $60,000 at opening, about 1,450 books, plus an amount equal to 25% of each year's direct costs. The rate follows the rental library: one copy for each rental shipped from July to November (59.5% of the year's rentals) plus 5%, carried at cost less $7.50 for each rental completed, plus used copies held for sale. That is about 4,000 rental copies for the fall rush in Year 1 and about 14,100 in Year 5, with each copy rented about 1.6 times a year. Year-end stock grows from $123,825 to $314,742. Measured on the book cost used up (the copy cost in rentals and the purchase cost of used copies sold), stock turns once in Year 1 and 1.3 times from Year 3. Direct costs include postage and card fees, so they are not used for turns. A stock position 20% heavier is a row in the sensitivity table.
- Card payments settle in about three days, so receivables are small. Carriers, the platform and suppliers are paid at purchase, so the model carries no payables, and seller payouts held until delivery sit outside the cash figures. Edition write-downs of $7,000 in Year 1 rising to $26,000 in Year 5 are charged as an expense and treated as cash, which in effect replaces the stock written off. That is 7% to 9% of average stock at cost each year; a bad edition year at three times the write-down is a row in the sensitivity table.
- Payroll adds 27% to wages for payroll taxes, health insurance, workers' compensation and a retirement match (15% for the part-time coordinator), and nothing for agency staff. Agency staff are charged at a bill rate of $26 an hour, shown as $54,000 for a full-time year. Wages in the personnel table are launch rates and planning figures, to be checked against current Indianapolis postings; pay raises of 3% a year are charged as a separate line from Year 2. Indiana's minimum wage is $7.25 an hour, the same as the federal rate, and the lowest wage in the model is the part-time coordinator at about $20 an hour. The fulfillment associates at $35,000 to $36,000 work out near $17 an hour. The receiving lead's $39,000 is above the $684-a-week salary level in the Department of Labor's overtime guidance ($35,568 a year), a level that has been revised before and should be confirmed. A lead who spends the day handling stock is likely to be paid hourly with overtime, which is one reason August cover comes from an agency.
- Rent is a planning figure: 2,800 square feet of flex space at about $9.65 a square foot a year including common-area charges, to be checked against current Indianapolis listings, then 3,800 square feet from Year 4. Utilities are separate. The platform build is $48,000, a planning figure to be confirmed by two quotes, and a contract developer is retained afterwards.
- The seasonal line is $150,000 and is available from January 2028. It carries a commitment fee of 0.5% a year on the line ($750) and interest at the term-loan rate on the amounts drawn; both are planning figures to be confirmed with the bank. Draws are sized to hold $50,000 of cash at each month-end, about three weeks of Year 5 fixed costs, and the line cost in the P&L is rounded up from the fee plus interest on the estimated draws ($750, $750, $1,156 and $1,362 in Years 2 to 5 of the base case).
- Tax is charged at the 21% federal corporate rate (26 U.S.C. 11(b)) and the Indiana corporate rate, which the Department of Revenue's tax-types page gives as 4.9% and which may change. The tax base leaves out the $68,300 of start-up costs, which would lower the tax, and does not apply the federal rule that a loss carryforward can offset only 80% of taxable income; that rule would move about $2,400 of tax from Year 4 into Years 2 and 3. The Year 1 loss is carried forward. The LLC could elect S corporation treatment, which moves the tax to its owners' returns; corporate rates are a conservative stand-in.
- The one owner distribution is $50,000 in Year 5, 42% of that year's net income and below the $65,264 of cash left after operations and loan principal; it is paid in December, after the seasonal line has been cleared. Cumulative net income after start-up costs is $91,329 by Year 5. The investors' return beyond that depends on a later sale or buyback of the company, which this plan does not forecast. The bank loan stays in place rather than being repaid early.

Rentals are the base: 65% of Year 1 revenue and 64% in Year 5. Used sales are 31% of Year 1 and 28% of Year 5. Marketplace fees grow from 1.5% to 5.1% of revenue and carry no stock. The volumes are small by design: 1,200 completed sales in Year 1 is about 0.6 for every store customer, and 14,500 in Year 5 is about one for every two books the store ships. A two-sided market without a brand fills slowly, so Year 1 earns only $7,440 from it. Revenue grows 77% in Year 2, the first year with two full terms of repeat customers, then slows to 21% by Year 5.

August alone brings in $153,713, 31% of the year, and August, September and December together bring in 64%. January, a soft launch, is 6%. April is the low month at $9,836. EBITDA is positive in August ($50,540), September ($10,493) and December ($20,192) and negative in the other nine months. The monthly series covers operating results and capital items only. It leaves out the year's stock and receivables build of $67,898, which is why its December balance of $470,339 cannot match the $402,441 year-end close in the cash table. Its July balance, less three days of receivables, is $420,000; once $93,000 of stock bought ahead of the fall rush is taken out, and agency pay is booked when worked (about $11,000 less by July), and loan payments are spread evenly rather than on the interest-only schedule (about $1,000 more by July), July falls to about $337,000, the Year 1 figure in the July table in the cash section.

Marcus and a receiving lead run the warehouse from January. A staffing agency supplies peak-month cover: 6 person-months in Year 1, 8 in Year 2, 10 in Year 3, 13 in Year 4 and 15 in Year 5. Year 1 bookings are one worker in July for the stock arriving ahead of the term, two in August, one in September and two in December; later years add January and May, when the fall and spring returns come in. The table shows the role at a full-time year's cost of $54,000 (a $26 an hour bill rate), and the cost in each year is that figure times the person-months over twelve. Its year-end columns show 1 whenever agency staff are booked in December; the December booking is 2 in Years 1 and 2, 3 in Year 3, 4 in Year 4 and 5 in Year 5. A part-time customer support and seller trust coordinator joins in month 11, ahead of the spring rush, and a full-time marketplace support and trust agent in month 26, so support runs at 1.5 people by Year 3. A fulfillment associate starts in month 14, a second associate in month 27, the campus marketing coordinator in month 32 and a third associate in month 40. Marcus's $66,000 is already in the costs, so profit here means what is left after he is paid. The part-time coordinator is shown as 0.5.

| Net income after start-up costs | ($123,166) | $7,150 | $41,351 | $47,968 | $118,027 |
Year 1 loses $54,866 before start-up costs and $123,166 after them. Year 2 shows EBITDA of $13,998 and net income of $7,150. Income tax is nil until Year 4, when it is $13,772, and rises to $39,072 in Year 5, because the early loss is carried forward. EBITDA margin moves from 3.7% in Year 3 to 8.2% in Year 5. Payroll falls from 33% of revenue in Year 1 to 27% in Year 5 while the direct-cost rate is held flat, and Year 5 is the least secure figure in the plan because it depends on volume reaching 22,500 rentals. Marketing is 8.5% of revenue in Year 1 (10.9% with launch spend) and 5.3% in Year 5.
Cash movements
| Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | |

| Closing cash | $402,441 | $353,290 | $335,919 | $329,535 | $344,799 |
Closing cash stays above zero in every year, at $402,441 in Year 1, $353,290 in Year 2, $335,919 in Year 3, $329,535 in Year 4 and $344,799 in Year 5. These are December balances, taken after the fall and spring-order receipts, so they hide the summer dip. The table below estimates month-end cash in July, the lowest point of each year. It spreads each year's model totals over the 2027 monthly shape, pays for each month's books a month ahead, buys the year's stock growth in June and July, leaves three days of sales uncollected at each month-end, collects each prior December's receivables ($4,073 at the end of Year 1 rising to $13,443 at the end of Year 4) in January, books agency pay in the months worked and spreads other costs evenly. Book cost is a fixed share of revenue (15% of rentals, 47.7% of used sales), so it rises with prices, while the hours and stock tables count books at the flat $7.50 and $42. It is an estimate built from the model's annual totals, not a line of the model itself.
| Estimated July month-end cash | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 |
|---|---|---|---|---|---|
| Base case, before any borrowing | $337,000 | $183,000 | $78,000 | $2,000 | ($22,000) |
| Seasonal line drawn to hold $50,000, base | – | – | – | $48,000 | $72,000 |
| Downside case, before any borrowing | $346,000 | $182,000 | $89,000 | $5,000 | ($40,000) |
| Seasonal line drawn to hold $50,000, downside | – | – | – | $45,000 | $90,000 |
The dip deepens each year because the swing grows with volume while year-end cash stays between $329,535 and $344,799 from Year 3. The reserve and the line are sized together for Years 4 and 5, so in Year 1 the reserve is well above what that year needs; staging part of the investment would cut the idle cash, but a lender counts only committed capital. The base-case July balance is about $2,000 in Year 4, which is close to zero (about $10,000 with the flat $7.50 and $42 book costs the hours and stock tables use), and $22,000 below zero in Year 5 (about $9,000 below with flat costs). Holding $50,000 of cash takes draws of $48,000 and $72,000, and the $150,000 line covers the largest draw, $90,000 in the Year 5 downside, with $60,000 to spare. That draw is 34% of the downside's year-end stock at cost, and the base-case draw of $72,000 is 23% of base stock, so the line depends on the bank advancing at least that share of stock cost; if it advanced less, the owners would need to hold more cash. The downside July balance is above the base case in Years 1, 3 and 4 and about $1,400 below it in Year 2, because less stock is bought for lower sales and, from Year 2, hires start later, marketing is smaller and fewer agency workers are booked; in Year 5 the lower sales outweigh those savings. Its year-end cash is lower in every year. No lease deposit is in the cash figures: a deposit of one or two months' rent ($2,250 each) would come out of the reserve. The Year 1 operating outflow of $248,778 is the $123,166 loss after start-up costs plus $127,898 of stock and receivables ($60,000 of opening stock, $63,825 of added stock and $4,073 of receivables), less $2,286 of depreciation added back. The one distribution, $50,000, is in Year 5.

| Monthly revenue needed to cover operating costs | $49,461 | $70,864 | $98,154 | $124,737 | $137,000 |
| Debt service cover (EBITDA / interest + principal) | -6.1x | 1.3x | 4.5x | 6.4x | 15.3x |
Operating costs are covered when average monthly revenue is higher than the figure in the row below it. Year 1 averages $41,293 against $49,461 needed, Year 2 averages $73,271 against $70,864, and Year 3 has $8,175 of headroom a month. These are annual averages; in Year 1 nine months fall short of the cost line and August, September and December carry the rest. Debt service cover is negative in Year 1, because EBITDA is below zero while interest is due, so the loan agreement would need to waive the test for Year 1; the lender then relies on the reserve and the guarantee. Cover is 1.3x in Year 2, the level the $50,000 loan is sized to, then 4.5x in Year 3 and 6.4x in Year 4. Stock turns on book cost are 1.0 in Year 1, 1.2 in Year 2 and 1.3 from Year 3, measured on the book cost used up and not on postage or card fees.
If revenue lands 20% short
| Year 1 | Year 2 | Year 3 | Year 4 | Year 5 | |
|---|---|---|---|---|---|
| Revenue | $396,416 | $703,399 | $1,020,756 | $1,308,423 | $1,582,195 |
| Net income before start-up costs | ($96,722) | ($16,070) | $32,905 | $18 | $76,358 |
| Net income after start-up costs | ($165,022) | ($16,070) | $32,905 | $18 | $76,358 |
| Closing cash | $374,165 | $312,310 | $297,365 | $252,885 | $285,858 |
This case cuts every revenue line by 20% in every year and applies the response below from the month the owner could see the shortfall. Chargebacks and fraud losses fall with sales; stock write-downs are left as in the base case. Nothing changes in the first eight months. From month 9, after the August rush, Marcus takes a 20% pay cut. From Year 2, marketing is cut by 20% and one fewer agency worker is booked for each August and December. Every hire from month 13 starts six months later, the third fulfillment associate is dropped, the business stays in the first warehouse (rent grows 3% a year instead of stepping up in Year 4) and no distribution is paid. Stock buying falls with sales, which helps cash, and the line cost rises slightly with the larger draws. On those terms the business ends every year with cash in the bank, at no less than $252,885, and equity ends Year 1 at $454,978. Net income after start-up costs is ($165,022) in Year 1 and ($16,070) in Year 2, then $32,905 in Year 3, $18 in Year 4 and $76,358 in Year 5. Year 3 is helped by hires that start late and Year 4 carries all of them for the first full year, which is why Year 4 falls back to break-even. Debt service cover is -11.4x, -0.9x, 3.7x, 0.5x and 7.7x in Years 1 to 5, so a 1.25x test would fail in Years 1, 2 and 4. Without the response, the same shortfall would leave year-end cash at ($22,650) in Year 4 and ($148,491) in Year 5, with the $50,000 distribution still paid. The July balances in the cash section are the pressure point, and the downside needs the seasonal line in Years 4 and 5. The team would also be stretched in the fall terms, with fewer people handling 80% of the planned volume.
The ask to the bank follows from those cover figures: no cover test on Years 1 and 2, a first test of 1.25x on Year 3 results, which the base case meets (4.5x, 6.4x and 15.3x in Years 3 to 5), and a liquidity test as the alternative in any later year where cover falls short. Liquidity here is year-end cash plus the undrawn line; a floor of $300,000 compares with a downside low of $402,885 in Year 4.
What single changes do to the base case
Each row changes one input from the base case in every year, with no management response, and costs that move with sales (card fees, chargebacks and fraud losses) move with revenue. The direct-cost rows add the stated points to the rate on every revenue line, so the blended rate moves by the same amount in all years. The $45 rental row keeps the $23.50 cost per rental, which lifts the blended rate to 55.1%; the model applies the Year 1 mix to all years, so that row is read mainly for Years 1 to 3. The two opening rows lose Year 1 revenue only and hold the rate; they keep every cost except chargebacks, which scale with the lost revenue. Their Years 2 and 3 equal the base case, and Years 4 and 5 differ only through tax relief on the larger loss. Figures are net income after start-up costs, the lowest year-end cash (with its year) and the Year 5 July draw needed to hold $50,000 against the $150,000 line, estimated as in the cash section.
| Change | Year 1 | Year 2 | Year 3 | Lowest year-end cash | Year 5 line draw |
|---|---|---|---|---|---|
| Base case | ($123,166) | $7,150 | $41,351 | $329,535 (Year 4) | $72,000 |
| Revenue 10% lower | ($146,888) | ($34,975) | ($19,805) | $124,576 (Year 5) | $230,000 |
| Direct costs 3 points higher | ($138,032) | ($19,228) | $3,073 | $188,784 (Year 5) | $199,000 |
| Postage 10% higher ($6.60 a leg) | ($131,896) | ($8,341) | $18,871 | $253,177 (Year 5) | $144,000 |
| Book purchase cost 10% higher | ($135,316) | ($14,409) | $10,065 | $217,284 (Year 5) | $175,000 |
| Lost or ruined copies twice as many | ($133,406) | ($11,020) | $14,983 | $237,329 (Year 5) | $158,000 |
| Wages 10% higher | ($139,699) | ($17,570) | $3,696 | $209,371 (Year 5) | $196,000 |
| Rent 10% higher | ($125,866) | $4,370 | $38,491 | $320,505 (Year 4) | $82,000 |
| Edition write-downs three times as large | ($137,166) | ($14,850) | $9,351 | $223,090 (Year 5) | $183,000 |
| Rental price $45, unit costs unchanged | ($154,972) | ($49,250) | ($40,517) | ($2,783) (Year 5) | $344,000 |
| Stock 20% heavier (30% of direct costs) | ($123,166) | $7,150 | $41,351 | $287,403 (Year 4) | $123,000 |
| Opening two months late (live March 1, 2027) | ($149,067) | $7,150 | $41,351 | $310,018 (Year 3) | $91,000 |
| Not live until September 1, 2027 | ($264,549) | $7,150 | $41,351 | $194,536 (Year 3) | $187,000 |
The result is fragile. A 10% revenue shortfall with no response loses money in Years 1 to 4, leaves $124,576 of cash at the end of Year 5, and its Year 5 draw of $230,000 would exceed the $150,000 line. Any one of the direct-cost, wage or write-down rows puts Year 2 into loss and cuts Year 3 profit by more than half. The rental price is the most exposed input: at $45, Years 1 to 4 lose money, year-end cash is ($2,783) by Year 5 and the owners would have to raise more equity, so that price has to hold. The reserve covers both opening cases in Year 1. With a two-month slip, July cash is about $311,000 and year-end cash is $383,953. If the store misses August, July is about $340,000, the Year 1 low moves to November at about $266,000, and year-end cash is $301,525. The September opening is a different case from a longer slip: it removes the first fall rush, takes $100,916 out of Year 1 cash and pushes the Year 4 and 5 draws to $181,000 and $187,000, above the $150,000 line, so the owners would add equity or slow hiring. In eight of the twelve shock rows a Year 5 draw would pass the $150,000 line if nothing were done, which is why the downside response matters.
