Seller Financing Explained: The Note, the Standby, and Your Cash
A seller note is a piece of the price you agree to collect later. You are the lender for that piece. You are not the SBA, and you are not the senior lender. The useful question is what you receive at closing, what you are supposed to receive afterward, and whether you can live with the difference.
Seller financing can help a deal close that would otherwise stall, and it can support a price the buyer could not write a check for. A higher price is not guaranteed. Interest is not free money. You earn it by taking repayment risk. Eligible gain may qualify for installment reporting. Inventory and depreciation recapture can be treated differently. Read the IRS installment-sale rules in Publication 537 with your tax adviser before you compare one offer’s tax story with another’s. This page is the owner’s economics. It is not tax advice, legal advice, or lending advice.
The note is part of the price
In seller financing, you do not receive the full price at closing. You receive a portion then, and the rest over time, with interest if the note is a paying note. The instrument is usually a promissory note, often secured by the business assets. Security, position, and whether you can actually collect are negotiated, and a senior lender may sit in front of you.
You sell the business for $3 million. The buyer contributes $1.5 million of equity, obtains a $1 million loan, and you carry a $500,000 seller note at 6% interest over 5 years. You receive principal and interest monthly for 5 years.
That example is a paying note. It is not a template, a market rate, or an SBA rule. Change the equity, the senior loan, or the note, and the cash at close changes with them.
A paying note, as owners and buyers often write it, runs on a schedule measured in years, typically 3 to 7 years. That range describes a paying note of the kind in the example. It is not a standby period, and it is not a reading of an SBA rule.
A paying note
A paying note amortizes. Principal and interest come due on a schedule. You can underwrite it the way you would underwrite any private loan, with one uncomfortable fact: the collateral is the company you just sold, run by the person who now owns it.
Buyers want the note because it cuts the cash they need on day one, and because a deal that equity and a senior loan cannot carry can then close. They also read a note as a signal that you believe the company will keep performing. Sometimes that signal is true. Sometimes it is the cost of getting their signature.
SBA lenders often require or prefer a seller note as part of the structure. That sentence is an observation about how these deals get built. It is not a claim that any one lender, or any one SOP, will require a note on your file. Ask the lender on the file.
If the buyer performs, you collect interest and you still own the stream. If you need the full price in cash to fund a retirement or a next venture, a paying note can still be the wrong instrument. The cash is tied up for the life of the schedule.
Full standby
Full standby is the other shape, and it needs its own name.
You may be asked to carry a note that does not pay while the senior loan is outstanding. No principal. No interest. You wait. The senior lender is in front of you, and the reason you are waiting is the lender’s credit, not your preference for a delayed check.
How long that wait lasts, and what “full” requires on a given file, is the lender’s current reading of the rules and of the deal. This page does not state a standby period, a cap, or a percentage. Do not assume a fixed standby because a prior deal used one. Confirm the terms with the acquisition lender, and have your counsel read the note against the senior loan documents. Lien priority and any restriction on payments are part of that reading.
A standby note is still part of the price. It is not cash. It is not a paying note that happens to be quiet for a few quarters. If you are being asked to wait through the senior loan, price that wait, or refuse it.
What the stack does to cash at close
When a senior loan is in the deal, two cash numbers matter more than the headline price.
Seller cash at close is what you can actually take home when the documents are signed. It is the price, minus the note, minus the holdbacks, minus the costs that were always going to come out, minus anything the lender requires you to leave behind. A bigger note, or a note on standby, is a smaller check.
Buyer cash is what the buyer must bring, and what the lender will count. Equity injection and down payment are the lender’s questions. What percentage is required, what sources count, and whether a gift, a standby note, or a side arrangement qualifies are answers on the lender’s current file. Those answers move both sides’ cash. This page does not declare the percentage. Where published explanations disagree, do not resolve that here. The effect on your proceeds is yours. The determination goes to an acquisition lender and to your counsel.

Can you live on the note you are about to sign
Run the personal math before you congratulate yourself on the price.
What hits your account at close, after tax and deal costs. What the note is supposed to pay, and when. What happens to your spending if it pays nothing for as long as the senior lender requires. What happens if the buyer defaults and you are trying to take the company back under a senior lien you do not control.
The primary risk is buyer default. If the new owner cannot pay, you may be looking at a foreclosure to get the business back, and you may be looking at it from behind the senior lender. Secure the note. Judge the buyer’s ability to run the company with the same seriousness they use on your financials. What buyers look for is the seller-facing version of that test. A note does not fix a buyer who cannot operate.
Liquidity is the other risk. Your capital is in their company, and if the note is on standby it is not paying you. “I don’t need all the cash on day one” is a fair reason to carry a paying note. It is not a fair reason to sign a note you cannot eat on.
Before you accept the price the note is holding up, know how that price was built. The methods are in how to value the business before you sell. The IBBA publishes observations on deal terms. Those observations are context, not the terms of your note.
Refuse it, reprice it, or restructure it
A standby note is not a gift you owe the buyer. It is not automatic paper you should be flattered to hold.
You can refuse the structure. The buyer finds more equity, a different lender, or a different deal. You can reprice. A dollar you will not see for years is not a dollar of cash, and the price should say so. You can restructure. A smaller note that pays. A shorter wait, if the lender’s file allows it. More cash at close and a lower headline. Collateral, a guarantee, payment dates, interest, default remedies, and cure periods belong in the document your M&A attorney writes. If you are comparing two offers, compare seller cash at close and the note you can live on. Do not compare headlines.
The boundary
WCG does not originate the loan, does not opine on the SOP, and does not document the injection. We will talk about what the structure does to you. The lender determines credit. Your counsel documents it. Your tax adviser handles installment treatment.
If the note changes the decision
Sometimes you run the cash and discover you do not want to sell on those proceeds. That is a keep-or-sell question, not a note question. Make it on should I sell or keep it, or take the assessment.
If you are already inside a live acquisition and you need a judgment on the structure, go to Advisory & Coaching or Capital & Financing Partners. Neither one makes WCG the lender.
If you only needed the definition, you have it. If you need which manual the lender is about to use, that is the 2026 SOP article.
