What a seller note is, why lenders look closely at its payment terms, and the questions to settle before you agree to seller financing.
October 30, 2026
Seller financing is common in small business sales, and it often shows up inside an SBA-backed deal as a seller note. Used well, it can bridge a gap between the price and what the buyer can fund. Used carelessly, it can complicate the lender's review. This post covers seller notes in SBA business acquisitions: what they are, why lenders pay close attention to their terms, and what to settle before you sign.
Rules about seller notes are set by SBA's procedures and by each lender's policy, and both can change. Nothing here states a rule as fact. Treat it as a way to prepare the right questions.
A seller note is a loan from the seller to the buyer for part of the purchase price. Instead of receiving the full amount at closing, the seller agrees to be paid over time under a written promissory note. In an SBA-backed acquisition, the note usually sits alongside the lender's loan and the buyer's own cash.
Both sides often have reasons to consider one:
How a seller note fits into the structure depends on the lender and on SBA's Standard Operating Procedure (SBA SOP 50 10 (check the current revision)). Review the SBA 7(a) program page and confirm the lender's own requirements before agreeing to terms with a seller.
Lenders pay close attention to when seller note payments are due. A common concept is a standby arrangement, in which the seller agrees to defer some or all payments for a period so that the business's cash first supports the lender's loan. Whether standby terms are required, how long they last, and what payments are allowed during that time depend on the lender and SBA's current rules. Ask the lender what it needs before you negotiate the note, because changing a signed note later is much harder.
The reason lenders care is cash flow. Payments on a seller note come out of the same cash the business uses to repay the lender. For example, suppose a business produces $150,000 of annual cash flow available for debt service, and the bank loan requires $85,000 a year. If a seller note calls for another $12,000 a year in current payments, total debt service is $97,000 and the coverage ratio is $150,000 divided by $97,000, or about 1.55. If the note's payments are deferred and the lender does not count them, the ratio is $150,000 divided by $85,000, or about 1.76. The difference shows why terms matter. How a lender counts the note is its decision, and these numbers are illustrations only.
1. Ask the lender how it will treat the note. Find out whether it wants standby terms, how it counts payments, and whether the note can count toward your required cash.
2. Put the terms in writing. The amount, payment schedule, interest, term, and what happens at default should all be in the note.
3. Test the cash flow. Run your projections with the note payments in the numbers, including a slower revenue case.
4. Check the other documents. Make sure the purchase agreement, the note, and any security or subordination terms agree with one another.
5. Get professional review. An attorney and a CPA can review the note and explain the legal and tax effects for both sides.
Can a seller note count toward my required cash?
In some structures it may, but this depends on the lender and SBA's current rules. Ask the lender before you rely on it in your plan.
What does standby mean?
In general, the seller agrees to hold off on some or all payments for a set time. The specific requirements are lender- and SOP-dependent, so confirm them directly.
Does a seller note make approval easier?
Not automatically. It can help a deal work on paper, but the lender still reviews cash flow, credit, experience, and documentation. It can also add complexity.
Who holds the note if the business is sold again?
That depends on what the documents say. An attorney can explain what happens to the note and any security interest if ownership changes.
A seller note can be a useful piece of an acquisition, but it is also one of the pieces lenders examine most closely. Know what the note says, ask the lender how it will be treated, and model your cash flow with the payments included. Clear terms on paper now save difficult conversations later.
