Most shipping and mailbox store purchases are small SBA 7(a) loans, sometimes SBA Express, with the buyer's equity of at least 10% of total project costs and often a seller note. Lenders underwrite gross profit rather than sales, because most shipping revenue passes through to the carriers. They look at how much comes from higher-margin packing, supplies, printing and mailbox rentals, at prepaid mailbox rent the buyer must honor, and, for a franchised store, at the franchisor's approval, transfer terms and any required remodel. The lease and the owner's own time behind the counter complete the picture.

Sales are not the number that matters
When a customer ships a package through a store, most of what they pay goes to the carrier. The store keeps its markup, any volume incentives the carrier pays, and whatever it charged for packing and materials. So a store's top line can look large while the money it actually earns is a fraction of it. Two stores with the same sales can have very different earnings depending on their mix.
Lenders therefore rebuild the business by service line, starting from gross profit. They want the point-of-sale reports that break revenue and cost out by category, and they compare them with the tax returns, because stores and franchise systems do not all report shipping revenue the same way.
| Service line | How it earns | How a lender reads it |
|---|---|---|
| Carrier shipping | A markup over the store's carrier cost, plus volume incentives | Large in sales, thin in margin; exposed to carrier rate and program changes |
| Packing services and materials | Boxes, fill and labor, sold at a high margin | Where much of the profit is; tied to shipping volume |
| Mailbox rentals | Rent paid in advance for a term, usually renewed | The most recurring line; lenders ask for the box count and renewal history |
| Printing, copying and document services | Jobs for small businesses and walk-ins | Good margin; depends on equipment and on staff who can do the work |
| Notary, passport photos, shredding, key cutting and similar | Small fees per visit | Adds traffic; rarely a large share of profit |
| Returns drop-off and other programs run with carriers or marketplaces | Per-package fees under program agreements | Brings traffic; the agreements may not be the store's to transfer |
Mailboxes: recurring revenue with a liability attached
Private mailbox holders pay rent up front for several months or a year. Lenders like the line because it renews quietly and gives the store a base of regular visitors. Two things need handling in the purchase.
Prepaid rent. The seller has collected rent for months the buyer will have to serve. That is deferred revenue, and it belongs in the price: the usual fix is a credit to the buyer at closing for the unexpired rent, alongside the working capital peg. In plain numbers, if box holders have prepaid 30 for months after closing, the buyer serves those boxes without collecting that 30, and the loan should not finance cash the seller has already taken.
Postal paperwork. A store that receives mail for box holders operates as a commercial mail receiving agency and keeps postal authorization forms on file for each box holder. On a change of ownership the store's registration with the local post office, and the records behind it, need to be in order under the new owner. Lenders and franchisors ask how that will be handled, because a store that cannot receive mail for its box holders loses the line.
Ask for the mailbox list with each box's paid-through date before signing the letter of intent. It sizes both the recurring revenue and the credit owed to the buyer.
Franchised stores: the franchisor is part of the deal
Many shipping and mailbox stores are franchises. A franchise resale adds a party whose approval the lender needs before closing.
- Buyer approval and training. The franchisor approves the buyer, often after an application, interview and training program. Lenders will not close until that approval is in hand.
- Transfer fee and new agreement. A transfer usually carries a fee and may require the buyer to sign the franchisor's current agreement, with its current royalty and marketing terms. Those costs go into total project costs and into the cash flow the lender tests.
- Required refresh. Franchisors often require a remodel, new signage or equipment as a condition of transfer. That spending joins the project and raises the equity injection.
- Remaining term. Lenders read the franchise term the way they read a lease: it should run at least as long as the loan, or renew on known terms.
- Carrier and program relationships. In a franchise system, some carrier pricing and drop-off programs are arranged through the franchisor; in an independent store, they are the owner's own accounts and may need to be reopened in the buyer's name. Lenders ask which applies.
SBA lenders also review the franchise agreement for eligibility, looking at how much control the franchisor has over the business. Our page on financing a franchise resale covers the process in more detail, and change-of-control consents covers the other approvals a buyer needs.
Owner time, the lease and equipment
Many stores are run by the owner at the counter with a few part-time staff. If the seller works long hours and takes a modest salary, the P&L understates the cost of running the store. Lenders deduct a market salary for whoever will run it; a buyer planning to be absent must show the store still covers its payments after a manager's pay. See the buyer's salary in coverage and SDE versus EBITDA.
Location drives walk-in traffic, so the lease matters more than the store's modest build-out suggests. Lenders want it assigned with the landlord's consent and running, with options, as long as the loan; see lease assignment. Copiers, printers and point-of-sale systems are often leased; those leases are debt, and the payments count in coverage along with the acquisition loan.
Seasonality is predictable: the holiday shipping peak, and in many areas a busy tax season for printing and notary work. Lenders read monthly sales to confirm the slow months still carry the payments.
Small loans, and the terms that apply to them
Shipping store purchases are often among the smaller acquisition loans a lender writes, and several SBA rules apply differently at small sizes. SBA guarantees 85% of 7(a) loans of $150,000 or less and 75% above that. SBA Express loans go up to $500,000 with a 50% guaranty; some lenders use Express for small purchases because they can process it under their own procedures, while others prefer standard 7(a) for any acquisition. See SBA 7(a) versus SBA Express.
Rates are also capped by loan size, which matters more here than in larger deals, because small loans sit in the brackets with the widest caps.
| 7(a) loan amount | Maximum variable rate |
|---|---|
| $50,000 or less | Base rate plus 6.5% |
| $50,001 to $250,000 | Base rate plus 6% |
| $250,001 to $350,000 | Base rate plus 4.5% |
| Above $350,000 | Base rate plus 3% |
A cap is a ceiling, not the rate a lender will quote; see current SBA loan rates and SBA maximum interest rates. Where the amount financed, less appraised real estate and equipment, exceeds $250,000, SBA requires an independent business valuation from a qualified appraiser, and the loan for the purchase cannot exceed it.
Structuring the purchase
The buyer's equity injection must be at least 10% of total project costs, including any franchise transfer fee and required refresh. A seller note can supply up to half of that only on full standby for the life of the SBA loan; a note that pays currently is allowed but counts as debt. SBA prohibits an earnout to the seller, so a price that depends on shipping volume after closing has to be fixed. Goodwill amortizes over up to 10 years, and from 1 October 2026 change-of-ownership loans amortize over no more than 10 years except any real estate share.
The seller can stay to introduce business accounts and train the buyer, but in a complete change of ownership only as a consultant, for up to 12 months, or up to 24 months under SOP 50 10 8.1 from 1 October 2026. Coverage must be at least 1.15x, or 1.0x globally including the owners, and from 1 October 2026 a change of ownership must show 1.25x on historical results. Every owner of 20% or more guarantees the loan.
A buyer who already owns one store and is adding a second has a stronger file: a proven operator, and combined cash flow. See add-on acquisitions.
The file a lender needs
Transparent's SBA acquisition checklist, with the items lenders ask for in a shipping store deal:
- Business tax returns, 2–3 years, and the filing extension if the latest year isn't filed
- P&L and balance sheet with the latest full year of figures (never an older year), and a year-to-date P&L through last month-end
- Point-of-sale reports of sales and cost by service line, by month
- Mailbox list with each box's paid-through date
- Debt schedule, including copier and equipment leases, with copies of notes being paid off
- Personal tax returns, 2–3 years, and a personal financial statement for each buyer owning 20% or more
- The letter of intent, and for a franchise the franchise agreement, disclosure document and franchisor approval
- The lease and bank statements
- The buyer's resume (supports Form 1919) and a use-of-proceeds narrative
With those in hand, Transparent builds the full lender package — financing model, lender presentation, blind teaser and underwriting memo — in a day; by hand, it takes at least a week. The model starts from gross profit by line and credits the prepaid mailbox rent, so the lender sees the store's real earnings rather than its carrier pass-through. It goes to the SBA lenders in our book whose appetite fits; 278 write SBA 7(a) and 504. See the package and our SBA data page for private mail centers.
Common questions
- Why won't the lender use the store's total sales?
- Because most shipping revenue is paid straight to the carriers. Lenders underwrite gross profit and the earnings after operating costs, which is what can pay the loan. A store with a strong mix of packing, printing and mailbox revenue earns more on the same sales.
- Can I use SBA Express to buy a shipping store?
- Possibly. Express loans go up to $500,000 with a 50% guaranty, and some lenders use them for small purchases. Others prefer a standard 7(a) loan for acquisitions. The rules on equity injection, seller notes and earnouts apply either way.
- Who gets the mailbox rent the seller already collected?
- The seller collected it, but the buyer has to provide the service. The usual answer is a credit to the buyer at closing for the unexpired rent, calculated from the mailbox list.
- Does the franchisor have to approve me before the lender closes?
- Yes. Lenders will not close a franchise resale until the franchisor has approved the buyer and the transfer terms, including any fee and required remodel, are known and included in the project.
- Can I keep working another job and own the store?
- Lenders will test whether the store covers its payments after paying a manager. If it does, an absentee plan can work; if the seller's unpaid hours were holding the numbers up, it usually does not.
