Seller financing: should you lend the buyer part of the price?

Short answer. Seller financing means you let the buyer pay part of the price over time, with interest, instead of at closing. It can widen the pool of buyers and close a financing gap, but your money then depends on the buyer's ability to pay and on how they run the business. Protect it with a solid down payment, security, clear default terms and regular reporting.

Key takeaways

• Seller financing is a loan from you to the buyer, repaid from the business you just sold them.
• It can help a deal happen, but you carry credit risk after you've given up control.
• The payment at closing is the part you're sure of. Make it count.
• Security, guarantees, reporting and default terms turn a promise into a protected loan.
• It's not the same as an earn-out: the amount is fixed, but payment still isn't certain.

What is seller financing?

In a seller-financed deal, the buyer pays part of the price at closing and owes you the rest. They repay it in instalments, with interest, over an agreed period. The arrangement is written in a promissory note or a loan agreement, often called a seller note or vendor loan.

The money to repay you usually comes from the business itself: its profit, month after month. That's the key point. You're lending against the future of a business you no longer run.

Why do buyers ask for it?

They can't fund the full price

Many buyers of small and mid-size online businesses combine their own money with a bank loan, and still come up short. A seller note fills the gap.

It signals confidence

If you're willing to be paid over time, you're telling the buyer you believe the business will keep producing profit. Some buyers read reluctance as a warning.

It can make a lender more comfortable

Where a bank is involved, a seller note can sit alongside the bank loan. Lenders often set their own rules for how such notes can be repaid. In the US, for example, the SBA's lending rules restrict how and when a seller note can be repaid when it's used as part of the buyer's down payment, and those rules were tightened in 2025. If the buyer is using a bank or government-backed loan, ask early what the lender will allow.

What are the risks for the seller?

The buyer can't pay

The most obvious one. If the business underperforms, or the buyer has other debts, your instalments may be late or stop.

The business is run differently

After closing, the buyer decides the ad budget, the inventory, the team. If they run it badly, the profit that was supposed to repay you shrinks.

You're behind the bank

If there's a bank loan too, the bank will usually be repaid first and have first claim on the assets. Your note is subordinated: you get paid after them, and you may not be able to act on a default without their consent.

Recovering is slow

If the buyer stops paying, enforcing the note takes time and legal costs, and what you get back may be a business in worse shape than the one you sold.

How do I protect myself?

A meaningful payment at closing

The bigger the closing payment, the more the buyer has at stake and the less you're exposed. Ask yourself: if the note were never paid, would the closing payment alone be a price you could live with?

Security

Ask for security over the business: a pledge on the shares, a charge on the assets, or both, depending on the structure. If the buyer stops paying, you have a claim on what you sold.

Guarantees

A personal guarantee from the buyer, or a guarantee from their parent company if they're buying through a new entity. New companies set up just for an acquisition often have nothing else in them.

Reporting

Monthly or quarterly financial reports while the note is outstanding. You want to see trouble coming, not discover it when a payment is missed.

Covenants

Limits on what the buyer can do while they owe you: no selling the business without repaying you, no taking excessive money out, no new debt that ranks ahead of yours without consent.

Clear default terms

What counts as a default, how long the buyer has to fix it, and what you can do then: demand the whole balance, enforce the security, take back control. Cross-default clauses, so a default on the bank loan also counts as a default on yours.

Sensible terms

Interest rate, term and instalment schedule should be realistic for the business's cash flow. A schedule that's too aggressive increases the chance of default. One that's too long keeps you exposed for years.

What does a seller note look like? (illustrative)

The figures are illustrative, to show how the pieces fit. They're not a recommendation.

In this example, 80% of the price arrives at closing. If the note ran into trouble, the seller would still have received most of the value, and would hold security over the business while the rest is repaid.

Seller financing vs earn-out: which is better?

They solve different problems.

Some deals use both. If you're offered both, read each with its own risk in mind. Our earn-out guide covers the conditional part in detail.

Does it change how I'm taxed?

It can. In the US, a sale where you receive at least one payment after the tax year of the sale is generally an installment sale, and the gain may be reported as payments arrive. The regular sale of inventory doesn't qualify for that treatment (IRS Publication 537). Other countries have their own rules. Ask your tax advisor before you agree the schedule. We list the questions to bring in taxes when selling an online business.

The structure of the deal also matters: whether you sell shares or assets changes who owes you the money and what security is available. See asset sale vs share sale.

When does seller financing make sense?

• The buyer is credible, with a track record of running similar businesses.
• The closing payment is substantial on its own.
• The note is secured, and backed by a guarantee.
• The business's profit comfortably covers the instalments.
• You'd still be satisfied if the note were paid late.

When those conditions aren't there, a lower price with more paid at closing may be the better deal.
