You've worked for decades to build your business. Now a buyer comes to the table and asks you to carry part of the purchase price yourself. It sounds counterintuitive, but seller financing in M&A is actually one of the most common deal structures in the middle market. And in some cases, it can help you close faster and walk away with more money in the long run.
But there's a catch. Done wrong, seller financing can leave you holding risk long after you thought the deal was done. This guide breaks down exactly how it works, when it makes sense, and how to protect yourself if you agree to it.
What Is Seller Financing in M&A?
Seller financing, also called a seller note or owner financing, is when the business owner agrees to accept a portion of the sale price as a structured payment over time, rather than receiving all cash at closing.
Here's a simple example. Say your business sells for $10 million. A buyer may offer $8 million in cash at closing and ask you to carry a $2 million seller note, repaid over 3–5 years with interest. You get most of your money upfront, and the buyer fills the gap they couldn't finance through a bank or private equity.
In middle-market M&A, particularly for businesses with $5 million to $100 million in revenue, seller notes appear in a significant portion of deals, especially when buyers are using SBA loans, bank financing, or have limited equity available.
Why Buyers Request Seller Financing
It Fills the Financing Gap
Most buyers, even well-funded ones, can't always source 100% of the purchase price in cash or third-party debt. Lenders typically cap financing at 60%–80% of enterprise value, depending on the business's financials and collateral. A seller note bridges the gap between what the bank will lend and what the seller is asking.
It Signals Confidence from the Seller
When a seller agrees to carry a note, buyers view it as a vote of confidence. It signals that the seller believes the business will continue performing well enough to repay the note. This can actually help justify a higher total purchase price.
It Speeds Up the Transaction
Seller notes can eliminate months of additional financing negotiations. When a deal can close faster, both sides benefit, there's less risk of deal fatigue, market shifts, or employee uncertainty.
When Seller Financing Makes Sense for Sellers
You should consider offering a seller note when:
- You want to maximize your total sale price and the buyer needs the note to justify a higher valuation
- The buyer is credible and the business has stable, predictable cash flows to support repayment
- The deal has a strong M&A advisor representing your interests to negotiate the note terms
- You have diversified wealth outside this transaction and can absorb the repayment risk
- You're in a negotiation where multiple buyers are competing and a seller note helps one buyer beat out a cash-only but lower offer
When to Be Cautious About Seller Financing
Seller notes are not always the right move. Here's when you should push back:
- The buyer has limited operating experience and the note repayment depends entirely on business performance after your exit
- Your note would represent more than 15%–20% of the total deal value, that's an outsized portion of risk to carry
- There is no senior lender involved, which means less oversight of how the buyer runs the business post-closing
- Your attorney has not reviewed repayment security, interest rate, and what happens if the buyer defaults
A seller note is essentially a loan you're making to the buyer. Treat it that way. Demand collateral, a meaningful interest rate (typically 6%–10% in today's market), and clear default remedies.
How Seller Notes Are Typically Structured
Principal Amount
Most seller notes range from 5% to 20% of the total transaction value. Anything above 25% should raise questions about the buyer's overall financial strength.
Interest Rate
Seller notes typically carry interest rates between 5% and 10% annually, depending on deal risk and market conditions. This rate should reflect the risk you're taking as an unsecured or subordinated lender.
Term Length
Repayment terms generally run 3 to 7 years. Shorter terms reduce your exposure but increase the buyer's cash flow pressure early. Your M&A advisor can help you find the right balance based on the specific deal.
Security and Collateral
In the best case, your note is secured by the business assets or the equity in the acquired company. In many deals, however, seller notes are subordinated to senior bank debt, meaning if the business fails, the bank gets paid before you do. Understand this clearly before you sign.
Subordination Agreement
If a senior lender is involved (SBA, conventional bank, etc.), they will almost always require your seller note to be subordinated. This means you won't receive payments on your note until the senior debt is current. Sometimes the bank will also restrict payments during certain financial covenant breaches.
Seller Financing vs. Earnouts: What's the Difference?
Business owners sometimes confuse seller notes with earnouts. They're different:
- A seller note is a fixed obligation, the buyer owes you a specific amount on a set schedule, regardless of business performance.
- An earnout is contingent, the buyer only pays if the business hits specific revenue or earnings targets after closing.
Seller notes are generally safer for sellers because repayment isn't tied to post-close performance. Earnouts put you in the position of depending on a buyer you no longer control to hit numbers on your behalf. For most sellers, a structured seller note is the preferable instrument.
Tax Considerations for Seller Financing
One underappreciated benefit of seller financing is the installment sale tax treatment under IRS rules. When you receive payments over time, you can spread your capital gains recognition across multiple tax years, which may reduce your total tax burden, especially if the gain would otherwise push you into a higher bracket in a single year.
This is a nuanced area of tax planning that should involve both your M&A advisor and your CPA before any deal closes. The structure of your seller note directly affects how installment sale rules apply.
How a Qualified M&A Advisor Protects You
If a buyer asks you to carry seller financing, the first call you should make is to an experienced M&A advisor. An M&A advisor will:
- Evaluate whether the buyer is financially strong enough to repay your note
- Negotiate the interest rate, repayment schedule, and collateral to your advantage
- Run a competitive process to make sure you're not leaving leverage on the table by accepting note terms before talking to other buyers
- Structure the overall deal so the seller note complements, not undermines, your total exit value

Our goal is to make sure you understand exactly what you're agreeing to, and that the terms protect your interests long after closing day.
Conclusion
Seller financing in M&A can be a powerful tool for getting your deal done at a price you're proud of. But it's not free money, it's a loan you're extending to the buyer. The interest rate, term, collateral, and subordination terms all matter enormously.
If a buyer brings a seller note to the table, treat the negotiation with the same discipline you'd bring to any significant financial decision.

Frequently Asked Questions
Is seller financing common in middle-market M&A deals?
Yes. Seller notes appear in a significant share of deals, particularly those involving SBA or bank financing where the lender won't cover the full purchase price. They are most common in transactions valued between $2 million and $50 million.
What interest rate should I expect on a seller note?
Most seller notes carry rates between 5% and 10% annually. The right rate depends on your deal's specific risk profile, the creditworthiness of the buyer, and whether the note is secured or subordinated.
Can I negotiate the terms of a seller note?
Absolutely. Every element, interest rate, term, repayment schedule, security, and subordination, is negotiable. A qualified M&A advisor should lead this negotiation on your behalf.
What happens if the buyer defaults on a seller note?
Your remedies depend on the note terms and any security agreements in place. If your note is secured by business assets, you may have the right to reclaim those assets. If it's unsecured or subordinated, your options are more limited, which is why proper structuring matters before closing.
Does seller financing affect the final sale price?
In many cases, offering a seller note helps justify a higher total purchase price because it reduces the buyer's upfront cash requirement. However, the risk-adjusted value of the note needs to be weighed against the certainty of receiving all cash at closing.
