Seller Notes and Standby Paper in Small Acquisitions

Short answer: The seller note is the most useful instrument in small M&A, and the least understood. The seller carries part of the price as a loan repaid from the business, behind the senior lender. Market terms have been remarkably stable: around 7 percent, negotiated rather than floating, five-year terms on amortizing notes and ten on standby paper. It closes financing gaps the bank will not, keeps the seller invested in a clean handoff, and, structured correctly on an SBA deal, covers part of your down payment. The craft is in the standby mechanics, the tax story that persuades a reluctant seller, and knowing that one deal can carry more than one note.

Why sellers carry, and why it costs you less than it looks

A seller note reads like a favor to the buyer. The data says otherwise: sellers who offer financing clear meaningfully higher prices than all-cash sales, on the order of 20 to 30 percent more, because financing widens the buyer pool and signals confidence in the business. The seller is buying a better price with their own paper. Tax does the quiet persuading: on an installment note the seller generally recognizes gain as payments arrive rather than all in the sale year, spreading the tax across the note's life. When a seller resists carrying, the price premium and the installment treatment are the two arguments that move them, and they are both the seller's own interest, not the buyer's.

For the buyer, the note is capital the no-man's-land will not otherwise supply, and it is alignment: a seller holding paper answers the phone during transition in a way a cashed-out seller does not.

The standby rules, precisely

On an SBA deal the note has a second job, and exact mechanics decide whether it can do it. A seller note counts toward the buyer's 10 percent equity injection only if it is on full standby, no principal and no interest paid, for the entire life of the SBA loan, and only up to half the required injection. Many sellers refuse a ten-year full standby, reasonably, since it parks their money without cash flow for a decade.

Here is the framing most buyers miss: the standby requirement only bites if you need the note for the injection. Fund the full 10 percent in cash, and any seller note is simply subordinate debt on whatever terms the parties and the lender agree. A note on partial standby, interest-only for the early years, can keep payments out of the debt-service calculation if the lender agrees, softening the ask without the full decade of silence. Confirm with the lender before you structure around it.

One deal, several notes

Because the standby note and the amortizing note do different jobs, sophisticated deals often carry both: one slice on full standby covering part of the injection, another amortizing from close so the seller sees cash flow, sometimes a third bridging a specific gap. Add the earnout-shaped variant, the forgivable note where a slice is forgiven if performance falls short, documented as a price reduction and permitted where true earnouts are barred, and the seller-paper toolkit covers most of the gaps a deal can present. Each layer has its own priority, rate, and trigger, which is what building a capital stack means in practice.

The watch-outs are symmetrical. For the buyer: a balloon at the senior loan's maturity needs a refinance plan set at close, not discovered in year nine. For the seller: the note is only as good as the business's health, which is why a seller should want the buyer well-capitalized rather than stretched. A note both sides can live with is usually the sign of a deal priced right, and sizing it inside the whole structure is Deal Structure work.
