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 standard SBA acquisition, the structure looks like this: the SBA 7(a) loan covers the majority of the purchase price (typically 70-85%), the buyer contributes a 10% equity injection, and the seller carries the remaining 15-20% as a note.

That gap is where the seller note lives.

What Does "Full Standby" Mean?

Full standby means the seller note goes completely dormant during the SBA loan term.

No principal payments. No interest payments. Nothing.

The seller receives their note payment only after the SBA loan is paid off or refinanced, which typically happens at the end of a 10-year term. At that point, the buyer either pays the note in full, refinances it, or negotiates a new structure with the seller.

This is different from a partial standby arrangement, where the seller receives interest-only payments during the SBA loan term. Partial standby still reduces buyer cash flow. Full standby does not.

The SBA allows seller notes to act as equity in the deal structure when placed on full standby. That is why the standard Regalis structure works: the 5% seller note on full standby satisfies part of the 10% equity injection requirement alongside the 5% buyer cash.

The SBA requires that any seller note used as equity inject must be on full standby for the entire term 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 a full standby seller note, the seller gets roughly 80-85% of the purchase price in cash at closing, which on a $600K deal is $490K to $510K wired to them on day one. The remaining $90K to $120K comes later. 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 2.05x DSCR on SBA debt service alone gives the buyer meaningful cushion. 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 $90K 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.

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?

Yes, under SBA guidelines, a seller note placed on full standby can count as equity in the transaction. The standard structure uses 5% buyer cash plus a 5% seller note on full standby to satisfy the 10% equity injection requirement. The seller note must be fully subordinated to the SBA loan and cannot have any payment obligation during the SBA loan term to qualify as 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.
