Seller Financing in an SBA Acquisition: How Seller Notes Actually Work
September 1, 2026 · FTI Capital
A seller willing to carry part of the price is the most underused piece of leverage in a business acquisition. Buyers spend weeks hunting for more cash, grinding on the price, or trying to talk a lender into a bigger loan — while the person on the other side of the table can often solve the same problem with a signature, and has reasons of their own to want to.
Seller financing appears in a large share of the acquisition deals we work on, and it does more than plug a funding hole. Structured correctly it can cut the cash you bring to closing, improve how the deal underwrites, and keep the seller invested in a clean handoff. Structured carelessly it can quietly fail to count for anything, or leave you with a second payment the business can't carry. FTI Capital is a broker and advisor; we don't lend the money. We structure these notes and take the package to the SBA lenders whose appetite actually fits.
The 30-second version
What a seller note is — and what it isn't
Mechanically it's simple. Instead of receiving the full price at closing, the seller receives most of it and takes a promissory note for the rest, secured or unsecured, at an agreed rate and term. You make payments to the seller much as you would to a bank.
What it isn't: a favor, or a soft obligation. A seller note is real debt with a real payment and real remedies if you miss it. It's also not automatically credited as equity — the single most common misunderstanding we correct. A note does equity work only if it's structured to do equity work, and that structure has to exist in the documents before the file is submitted, not be argued for afterward.
The three jobs a seller note can do
- Cover part of your equity injection. On standby, it reduces the cash you personally need at closing. For a buyer who's short, this is usually the highest-leverage change available to the deal — see our post on SBA down payments for how the injection gets calculated in the first place.
- Bridge a valuation gap. When the seller's price and the number a lender will support don't meet, a note can carry the difference — sometimes tied to performance, so the seller gets paid for the value they say is there.
- Keep the seller in the deal. A seller still owed money has a durable reason to hand over relationships properly, answer the phone in month four, and honor the transition period. Lenders read it the same way.
Standby: the word the whole structure turns on
"Standby" means the seller contractually agrees not to receive payments on their note for a defined period, and to sit behind the SBA lender in priority. It's documented in a standby agreement the lender provides. The distinctions matter more than the dollar amount does.
Full standby
No payments at all — not principal, not interest — for the standby period. This is the version that can commonly count toward your equity injection, provided the standby runs long enough relative to the SBA loan's term. Interest typically still accrues; it just isn't paid until the standby lifts.
Partial standby
Interest-only payments during the standby period, with principal deferred. Easier to sell to a seller who wants some current income. Lenders vary in how they treat it, and it generally does less for your injection than full standby — sometimes nothing at all.
No standby
The note amortizes from closing. Clean for the seller, and perfectly workable in plenty of deals, but it's simply additional debt: it counts against your debt service coverage and does no equity work. If coverage is already thin, this is the version that sinks the file.
What the lender is actually evaluating
Two questions, and they're separate. First: does this note qualify to count as equity under the program rules and this lender's overlay? That's a structure and documentation question. Second: can the business carry the total debt once the note starts paying? That one is arithmetic, and it's where deals with generous seller notes sometimes fail anyway.
The second question catches people off guard. A standby that expires in year three means your debt service in year three includes both the SBA payment and the seller note payment. Underwriters model that step-up. If the business only clears coverage while the note is silent, the standby is hiding a structural problem rather than solving it — and it is much better to find that now than in year three.
Terms worth negotiating deliberately
- Amount — both as a share of the price and against what your injection actually needs. Bigger isn't automatically better once you model the coverage step-up.
- Standby period and type — full versus interest-only, and for how long. This is the term with the most impact on whether the note helps you at all.
- Rate. Sellers often anchor high. It's negotiable, and it compounds into the payment that has to clear coverage later.
- Amortization and any balloon. A balloon at the end of a short note is a refinancing event you're committing to years in advance. Go in knowing that.
- Security and subordination. The SBA lender will require the note to sit behind its lien; expect the standby agreement to be non-negotiable in substance.
- Offset rights. If the seller's representations turn out to be wrong, offsetting against an unpaid note is far more useful than a claim against someone who already has all your money.
- Guarantees and default terms — what's personally guaranteed on the note, and what happens on a default that isn't your fault.
How to actually get a seller to agree
Most sellers' first reaction to carrying paper is resistance, and it's usually about risk rather than money. The arguments that work, roughly in order of effectiveness:
- The deal closes. A seller who won't carry anything may be waiting a long while for an all-cash buyer at their price. This is the real argument, and it lands better as arithmetic than as pressure.
- Tax treatment. Spreading proceeds across years can matter to a seller's tax picture. Not your advice to give — but it's a good reason for them to call their CPA, and that conversation often does the persuading for you.
- Yield. The note earns interest. Against what the same money would do parked elsewhere, a well-secured note on a business they know intimately is not a bad instrument.
- They know the business better than any lender does. A seller who genuinely believes the business is sound finds it awkward to argue that carrying a modest note is dangerous.
- Scope the ask precisely. "Would you consider carrying ten percent on standby for three years?" is a negotiation. "Will you finance part of this?" invites a no.
Where seller notes go wrong
- Agreed in the LOI without the standby language. The amount gets negotiated, the standby doesn't, and the seller treats the terms as settled by the time the lender asks for full standby. Raise standby in the same breath as the number.
- Assuming the note counts as injection because it exists. It counts if it's structured and documented to count. Confirm the treatment with the actual lender before you commit to the structure.
- Ignoring the payment step-up. Coverage that only works during the standby period isn't coverage.
- A side agreement. Any arrangement to pay the seller during a standby period — a consulting agreement that's really note payments, a handshake to catch up later — is a serious problem, not a clever workaround. Don't.
- Stacking too much total debt. A seller note plus an equipment loan plus a working capital line can each look fine alone and fail together.
- Leaving the seller's advisors out until late. The seller's attorney and CPA will have opinions about carrying paper. Far better to hear them in week two than the week before closing.
Refinancing a seller note later
Existing seller notes come up constantly on the refinance side — a buyer who took one on two or three years ago and now wants it consolidated into longer-term financing, or wants the obligation off the balance sheet. That can often be arranged, and it's a different underwriting conversation than the acquisition was: the business now has an operating history under your ownership, which usually helps rather than hurts. Our post on how SBA 7(a) refinancing works covers the mechanics.
Where this fits in the rest of your file
A seller note is one component of a package that has to hold together. The injection has to be documented and traceable, the projections have to show coverage through the step-up, and the note's terms have to match what the purchase agreement says. Our post on what makes a strong SBA loan application covers how the pieces fit — and if the deal is a partner buyout rather than an outside purchase, the buyout mechanics work somewhat differently.
How this works with FTI
- Consult. A free call to look at the deal, the cash you have, and whether a seller note is the right tool — including a straight read on what coverage looks like once the standby lifts.
- Structure & package. We shape the note alongside the rest of the injection, model the step-up, and build a package where the note's treatment isn't left to interpretation.
- Match & close. We take it to the SBA lenders in our network whose appetite fits the deal and who treat seller notes the way this structure needs, then manage underwriting through to closing. We've arranged $41.3M+ across 28 funded deals, and lender selection is where most of that experience shows up.
