Seller Note (Full Standby): What It Means for Business Buyers

What Is a Seller Note?

A seller note is financing provided by the seller of the business. Instead of receiving 100% of the purchase price in cash at closing, the seller accepts a portion of the price as a promissory note, paid back over time by the buyer.

In a clean SBA acquisition, the structure looks like this: the SBA 7(a) loan covers 90% of the deal, the buyer contributes 5% cash, and the seller carries a 5% note on full standby that counts as the rest of the 10% equity injection. The cash plus the standby note make up the injection.

That standby slice is where the equity-qualifying seller note lives. A seller can also carry more than 5% to help bridge to the price, but only the first 5% on full standby counts as equity. Anything above that is separately negotiated subordinate debt that earns no equity credit.

What Does "Full Standby" Mean?

Full standby means the seller note pays nothing for the entire life of the SBA loan.

No principal payments. No interest payments. Nothing, for the full term, typically 10 years.

The seller receives their note payment only after the SBA loan is paid off or refinanced. At that point, the buyer either pays the note in full, refinances it, or negotiates a new structure with the seller.

Partial standby is not the same thing and does not qualify. A note where the seller receives interest-only payments, or principal after a set period, is on partial standby. Under SBA SOP 50 10 8 (effective June 1, 2025), only a note on full standby for the life of the loan can count toward the buyer's equity injection. A note that is not on full standby counts as zero equity.

When a seller note does qualify, it can cover at most 50% of the required injection, which is 5% on a 10% requirement. That is why the standard Regalis structure pairs a 5% seller note on full standby with 5% genuine non-borrowed cash to satisfy the 10% equity injection. The note cannot replace the cash half, because at least 5% of total project cost must be genuine non-borrowed cash.

The older market rule of "standby for two years" is obsolete. The current SOP requires full standby for the entire life of the SBA loan.

Why Do Sellers Agree to This?

On the surface, accepting a 0% note with no payments for 10 years sounds like a bad deal for the seller. In practice, most sellers agree because the alternative is worse.

An all-cash deal at closing requires a larger SBA loan, which either kills the debt service coverage or is not available at all. A deal that does not close is worth nothing to the seller.

With the clean full standby structure, the seller gets roughly 95% of the purchase price in cash at closing, which on a $600K deal is about $570K wired to them on day one. The 5% standby slice, about $30K, comes later. If the seller carries more than that to help bridge the gap, the extra is separately negotiated subordinate debt rather than the equity piece. Most sellers, particularly those who have already found a qualified buyer and are motivated to retire or exit, take that tradeoff.

The subordination is also real. The seller note sits behind the SBA loan in priority. The seller is betting on the continued performance of the business, which they built. That alignment of incentives is part of why the structure works.

How Does This Apply to a Real Deal?

Here is how a seller note structures into a $600K acquisition as of Q1 2026.

These are rough estimates based on Q1 2026 market data. Actual terms depend on individual qualification, lender, and seller negotiation.

Because the seller note is on full standby, the buyer's annual debt service only includes the SBA loan payment. No seller note payments hit the income statement during the 10-year term.

A 1.83x DSCR on SBA debt service alone gives the buyer meaningful cushion above the 1.5x Regalis floor. If the seller note required even interest-only payments, that coverage ratio would compress.

Based on Regalis Capital's analysis of recent acquisitions, a full standby seller note can improve a buyer's effective DSCR by 0.2x to 0.4x compared to a partial standby or amortizing seller note on the same deal.

What Happens After the SBA Loan Term?

When the SBA loan is paid off or refinanced at the end of the 10-year term, the seller note comes due. The specific repayment terms are negotiated at closing and spelled out in the promissory note.

Common outcomes include a balloon payment from the business's accumulated cash reserves, refinancing the seller note into a new conventional loan, or a negotiated payoff with the seller at a discount.

At 0% interest, the real cost of that $30K standby note paid in year 10 is far lower than its face value in today's dollars. Buyers who plan for it treat the seller note as a low-cost deferred obligation with minimal friction.

Related Terms

Understanding seller notes requires understanding the broader deal structure. These terms work together.

Equity Injection covers the 10% contribution requirement, the 5% genuine non-borrowed cash floor, and how a 5% seller note on full standby covers the rest.

SBA 7(a) Loan is the primary financing vehicle that the seller note subordinates to.

DSCR (Debt Service Coverage Ratio) is the metric most directly improved by keeping the seller note on full standby.

Frequently Asked Questions

How long does a full standby seller note last?

A full standby seller note runs concurrent with the SBA loan term, which is typically 10 years for business acquisitions. During that period, the seller receives no payments of principal or interest. After the SBA loan is paid off or refinanced, the seller note becomes payable according to the terms negotiated at closing.

What is a typical interest rate on a full standby seller note?

The target is 0% interest, and Regalis Capital's deal team achieves 0% on more than 90% of its transactions. Some deals close with a nominal rate of 2-3% if the seller negotiates for it, but that rate is still deferred and does not accrue payments during the standby period. A 0% rate on a 10-year standby note is a material economic benefit to the buyer.

Does the seller note count toward the SBA equity injection requirement?

Only on full standby. Under SBA SOP 50 10 8 (effective June 1, 2025), a seller note counts toward equity injection only when it is on full standby for the life of the SBA loan, and it can cover at most 50% of the requirement. The standard structure is 5% buyer cash plus a 5% seller note on full standby. A note not on full standby counts as zero equity.

Ready to Structure a Deal With a Full Standby Seller Note?

Negotiating a full standby seller note at 0% interest is not automatic. It requires understanding how to frame the ask, what sellers need to feel comfortable, and how to document the structure correctly for SBA approval.
