Seller Financing Explained: What Sellers Actually Agree To

Most sellers think of seller financing as something they offer to sweeten a deal. A negotiating chip. A way to attract buyers who cannot get bank financing.

That framing is backwards.

In most small business acquisitions today, seller financing is a structural requirement, not a concession. If you are selling a business under $5M, there is a very good chance the buyer’s lender will expect a seller note as part of the deal. And understanding what you are actually agreeing to, why the structure exists, and how it affects your closing-day proceeds changes the way you should be thinking about every offer that lands on your desk.

What Seller Financing Actually Is

Seller financing is when the seller of a business accepts a portion of the purchase price over time instead of receiving the full amount at closing.

Instead of the buyer paying 100% of the acquisition price upfront through some combination of bank loan and cash, you effectively become a lender for part of the deal. The buyer gives you a promissory note committing to repay that amount, with or without interest, over a defined period. In a typical small business acquisition, seller financing bridges the gap between what the bank will lend and the total price.

A simple structure looks like this: the buyer puts in 10% equity, an SBA 7(a) loan covers 80%, and a seller note covers the remaining 10%. At closing, you receive 90% of the agreed purchase price. The final 10% comes to you over time according to the note terms.

That 80/10/10 split is not the only configuration, but it is the most common one we see across deals in this size range.

The SBA Connection Most Sellers Miss

Here is what catches sellers off guard once they are already deep in a deal: SBA 7(a) financing almost always requires a seller note.

The SBA sets guidelines that lenders follow closely. When a deal is structured for SBA financing, the buyer typically needs to demonstrate a minimum 10% equity injection. But the SBA also allows part of the seller’s proceeds to be held back as a promissory note, which counts toward certain deal structure requirements. You can verify the broad strokes of how SBA 7(a) loans work on SBA.gov, though the real specifics come from the lender’s internal credit policies.

More importantly, seller notes help the deal hit the debt service coverage ratio (DSCR) the lender needs to approve financing. The SBA and its approved lenders want to see that the business generates enough cash flow to cover loan payments comfortably, typically at a 1.25x DSCR minimum. Most qualified buyers and their advisory teams target 2.0x or better.

If the acquisition price is high relative to the business’s SDE, a seller note on standby reduces the annual debt load on the buyer. Lower annual debt payments mean a better DSCR. A better DSCR means the loan gets approved. The whole thing is a math exercise, and the seller note is one of the variables that makes the equation work.

So when a buyer backed by SBA financing asks for a seller note, they are not signaling weakness. They are doing what the structure requires to get a deal closed.

What “Standby” Actually Means for You as the Seller

This is the part that surprises sellers most.

When an SBA lender is involved, the seller note is typically placed on what is called full standby. That means you, as the seller, receive no payments during the SBA loan’s active period. The note sits there. The buyer owes you the money. But payments do not begin until the SBA loan is paid off or the lender releases the standby requirement.

The standard structure we see on 90% or more of SBA deals: a 10-year full standby note at 0% interest.

Zero interest. No payments. For a decade.

For sellers expecting to retire on note income or counting on monthly checks from the buyer, this is a significant discovery. The money is real and it will come to you. But the timeline is not what most sellers picture when they hear “seller financing.”

The reason buyers push for 0% and full standby is straightforward: the note on standby does not count against debt service. If the note required monthly payments, it would eat into the business’s DSCR and potentially kill the lender’s approval entirely. Standby terms keep the deal financeable.

Your attorney should review the specific note terms in any LOI. But going in, expect standby, and expect 0% or near-zero interest if the buyer is using SBA financing. This is not an aggressive ask from the buyer. It is the standard.

How Seller Note Size Affects Your Negotiation

The size of the seller note matters more than sellers typically realize during LOI negotiations. Worth understanding before you get too deep into any deal.

Say you are selling a landscaping company doing $1.4M in revenue with $320K in SDE. A buyer and their advisory team underwrite the deal at 3.0x SDE, arriving at a $960K acquisition price. They structure it as:

Buyer equity: $96K (10%)
SBA 7(a) loan: $768K (80%)
Seller note: $96K (10%)

Your all-in sale price is $960K. You walk away at closing with $864K. The $96K note on 10-year standby at 0% comes to you a decade out.

Now consider what happens if the same buyer argues for a higher seller note, say 15%, or $144K. Your closing-day proceeds drop to $816K. You are essentially extending more financing to the buyer and accepting a longer wait on more of your money. That $48K difference is not trivial. It is real money you do not receive for 10 years.

This is worth negotiating. Sellers should push for the smallest seller note consistent with what the deal’s DSCR requires. A good buyer’s advisor can show you the underwriting model that drives the note size. You should ask to see it. If the DSCR clears at 10%, there is no structural reason you should accept 15%.

How to Think About Risk in a Seller Note

Sellers often ask: what happens if the buyer defaults?

Fair question. The seller note is a real loan you are extending. If the business struggles post-closing and the buyer cannot service the SBA debt, the SBA loan has seniority. You, as the seller note holder, are subordinate. In a workout or liquidation scenario, the SBA lender gets paid first. That is non-negotiable.

But this does not mean seller notes are inherently dangerous. It means you should think carefully about who you are selling to.

A buyer backed by a qualified advisory team, properly capitalized, with a realistic transition plan and a well-structured SBA package is a fundamentally different counterparty than an underprepared buyer scraping together financing from multiple thin sources. The gap between those two buyers is enormous, and it shows up in how the deal performs post-close.

The best protection against seller note risk is not a higher interest rate on the note. It is selling to a credible, well-funded buyer who has done real underwriting on the business before making an offer.

Seller Financing vs. an Earnout: Two Different Things

Sellers sometimes confuse seller financing with earnouts. They are different structures with very different risk profiles, and conflating them leads to bad negotiating decisions.

A seller note is a fixed obligation. The buyer owes you a set dollar amount per the promissory note, regardless of how the business performs after closing. If they agreed to pay you $96K over 10 years (or in a lump sum at year 10 under standby), they owe you $96K. Period.

An earnout is performance-based. The buyer pays you additional proceeds only if the business hits specified milestones after closing: revenue targets, EBITDA thresholds, customer retention rates. Earnouts are common in deals where there is a significant gap between what the seller thinks the business is worth and what the buyer is willing to pay based on historical financials.

Earnouts carry more risk for sellers. The post-closing performance of a business you no longer control determines whether you get paid. And disputes over earnout calculations are among the most litigated issues in small business M&A (something your M&A attorney will confirm if you ask).

If a buyer is offering a large earnout in lieu of a larger upfront price or a clean seller note, pressure-test the assumptions. Your attorney should define the calculation methodology in precise contract language before you sign anything. Vague earnout terms are how sellers end up in arbitration two years after closing.

All of that matters, but here is the part that trips up most sellers: confusing the two structures during LOI review and accidentally negotiating as if a seller note and an earnout carry the same risk. They do not.

Where Seller Financing Shows Up in the Deal Timeline

The seller note is not the last thing negotiated. It appears in the letter of intent.

The LOI is the buyer’s formal indication of intent to acquire, signed before due diligence begins. It will specify the purchase price, the proposed financing structure, and the seller note amount, term, interest rate, and standby period. Everything that matters about your seller note is outlined here, in principle, before diligence even starts.

Once you sign an LOI (typically with a 30 to 60 day exclusivity period), you have agreed in principle to those note terms. Trying to renegotiate the note after due diligence has begun is possible but creates friction and can kill the deal entirely. We have seen it happen enough times to know: the sellers who understand seller financing before the LOI arrives negotiate better terms than the ones who discover the mechanics mid-deal and react emotionally.

That is why you need to understand seller financing fully before you receive an LOI. Not after.

Seller Financing Explained: Getting to a Clean Close

The goal of every deal is a clean close. Seller financing, structured properly, is one of the mechanisms that makes that possible.

Sellers who refuse any seller note or demand all-cash deals substantially narrow their buyer pool. Cash buyers exist, but they are rare in the sub-$5M market. Most qualified, well-capitalized buyers in this range use SBA 7(a) financing. And SBA financing almost always involves some form of seller note.

The sellers who actually get deals closed are the ones who understand how the structure works, negotiate the note terms from an informed position, and focus their energy on finding a credible buyer who can execute. A smaller note at 0% interest from a buyer who closes is better than a theoretical all-cash offer that never materializes. Every time.

Frequently Asked Questions

What is seller financing in a business sale?

Seller financing is when the seller accepts a portion of the purchase price as a promissory note rather than cash at closing. The buyer repays that amount over time per the agreed note terms. In most small business acquisitions under $5M, seller financing covers 10% to 15% of the purchase price and is required as part of the SBA 7(a) loan structure.

Is a seller note risky for the seller?

There is real risk in any seller note because you become a subordinate lender to the buyer. If the buyer defaults, the SBA lender has priority over your note in any recovery. The best way to manage this risk is to sell to a credible, properly capitalized buyer with a realistic business plan, not to negotiate a higher interest rate on the note itself.

What does “full standby” mean on a seller note?

Full standby means the seller receives no payments on the note during the active period of the SBA loan, typically 10 years. The note exists but does not generate income during that time. Most SBA deals include a 10-year full standby note at 0% interest. This is the standard structure, not an unusual demand from the buyer.

Can you negotiate the size of the seller note?

Yes. Sellers should push for the smallest note consistent with what the deal’s debt service coverage requires. A good buyer will be able to show you the underwriting model that justifies the note size. If the DSCR works at a 10% seller note, there is no structural reason to accept 15% or 20%.

How is a seller note different from an earnout?

A seller note is a fixed obligation: the buyer owes you the agreed amount regardless of post-closing performance. An earnout is contingent on the business hitting specific milestones after closing. Seller notes are more predictable for sellers. Earnouts carry more uncertainty and are more frequently disputed in litigation.
