Earnouts, Seller Notes, and Escrow: How Risk Gets Split in a Business Sale

In most business sale transactions, the seller does not walk away with the full purchase price on closing day. The number on the term sheet and the number that clears your bank account are rarely the same. Part of the price gets tied to future performance, lent back to the buyer, or parked with a third party until claims clear. As of mid-2026, three structures do most of that work: the earnout, the seller note, and the escrow holdback. Each one answers the same question in a different way. Who carries the risk if the business stumbles after the deal closes, and when do you actually get paid?

Why doesn’t the full purchase price get paid at close in a business sale?

Buyers hold money back because they are pricing risk they cannot fully diligence before closing. The headline price assumes the business performs the way the financials say it will. A buyer writing a check for several million dollars wants protection in case revenue softens, a key customer leaves, or a problem surfaces that diligence missed.

So instead of paying everything up front, the buyer splits the price into money paid now and money paid later, contingent on something going right. That split is the whole game in deal structure. Two sellers can agree to the identical purchase price and walk away with very different amounts, because the structure behind that number was negotiated differently. If you want the wider view of how the business sale process works from offer to close, that is its own discussion. Here the focus is narrower. These are the three mechanisms that decide where your risk sits.

What is an earnout, and who carries the risk?

An earnout ties part of the purchase price to the business hitting agreed targets after the sale closes. The seller carries the risk, because the money is no longer guaranteed and the buyer now runs the company.

Earnouts appear in roughly 22% of private-target M&A deals, according to the SRS Acquiom 2025 M&A Deal Terms Study, which excludes life sciences. That figure reflects the broader private-target market and skews toward deals far larger than the $5M to $25M lower middle market, so read it as direction rather than a precise rate for smaller transactions.

Say a buyer offers $12 million for your company. Nine million at close, and three million as an earnout if the business reaches $2 million in EBITDA in the year after closing. Hit the target and you collect the full price. Land at $1.7 million in EBITDA and the formula may pay a fraction, or nothing, depending on how the contract is written. That three million was never promised. It was a bet on performance you no longer fully control.

The danger lives in the definitions. EBITDA can be pushed down by the buyer’s own decisions, including new overhead, reallocated costs, or a pause on the sales hires you would have made. If the contract does not spell out how the metric is calculated and what the buyer can and cannot do during the earnout period, you are exposed. A well-built earnout includes operating covenants, reporting rights, and a clear formula. A loose one is a promise with no enforcement behind it.

What is a seller note, and how does it get paid back?

A seller note is financing you provide to the buyer for part of the price, repaid over time with interest. You become a lender to your own buyer, and you collect on a schedule instead of all at once.

A seller note usually sits behind the buyer’s primary lender, an arrangement called subordination. If the business runs into trouble and cannot service all its debt, the senior lender gets paid first. Your note waits. That is the reason the interest rate on a seller note should reflect the real risk you are taking, not a token number, and why the security behind the note matters as much as the rate.

Seller notes also carry tax consequences. The IRS generally treats them as installment sales under Internal Revenue Code Section 453, which can spread your capital gains across the years you receive payments instead of taxing the full gain in the year of sale. The IRS rules on installment sales lay out how this works, and you should model it with your accountant before agreeing to a note, because the timing changes your after-tax proceeds.

What is an escrow holdback, and how much gets held back?

An escrow holdback parks a portion of the proceeds with a neutral third party to cover claims that surface after closing. The seller still owns that money, but cannot touch it until the holdback period ends.

The held-back amount sits in escrow for a defined period, often twelve to eighteen months, then releases to you if no valid claims have been made. If the buyer discovers that a representation you made was wrong, such as undisclosed litigation or overstated inventory, they make a claim against the escrow rather than chasing you separately. A working capital shortfall measured after close can pull from the same pool.

Escrow is the cleanest of the three structures, because the money is real and the release terms are written down. Your exposure is capped at the amount held, and both the size of the holdback and the length of the period are negotiated, not fixed. The seller who pushes for a smaller holdback and a shorter window keeps more cash working sooner.

Earnout vs seller note vs escrow holdback: how the risk compares

The three structures split risk in different ways, but the seller is the one waiting in all of them. The table below lines up what each one puts at stake.

Read down the third column and the differences sharpen. An earnout can pay nothing. A seller note can stall if the company struggles. An escrow holdback caps your downside at a known number. The structure you accept decides how much of the price is actually yours and how long you wait for it.

How deal structure changes what you actually keep when selling a business

These three structures do not operate in isolation in a business sale. They sit on top of a more basic decision, which is whether the deal is built as an asset sale or a stock sale. That choice changes your tax exposure and your liability on the same dollars before earnouts and notes ever enter the picture.

A seller note attached to an asset sale carries different tax mechanics than the same note inside a stock sale. An escrow that covers liabilities means one thing when you have transferred those liabilities and another when you have not. If you have not worked through the asset sale versus stock sale decision, do that first. It sets the frame that earnouts, seller notes, and escrow all fit into.

How to protect yourself before you negotiate structure

You protect yourself by tightening the structure before you sign, not after a dispute starts. By the time money is sitting in escrow or an earnout target has been missed, your leverage is gone. The work happens at the negotiating table.

Four moves matter most:

• Get your financials clean before you go to market, so the buyer has fewer reasons to hold money back.
• Define every earnout metric precisely and in writing, with operating covenants that limit what the buyer can do to your number.
• Cap and time-box the escrow holdback, and push for the shortest defensible period.
• Price the seller note’s risk into the interest rate and insist on real security, given that your note sits behind the senior lender.

Each of these is a negotiation, and each one moves real money. The seller who treats structure as an afterthought signs whatever the buyer’s counsel drafted. The seller who treats it as the heart of the business sale keeps more of the price and waits on less of it.

See where your risk sits

Earnouts are where deals get won or lost. The same is true of seller notes and escrow. Before you sit across from a buyer, you should know where your risk actually sits and what your company is worth right now.

It is not a formal valuation, but it is enough to walk into a structure conversation with your eyes open.
