An earn-out gets paid without a dispute when the purchase agreement fixes the metric, the accounting, the books and the dispute path before close, in a form both sides can recompute. Revenue is the hardest number to argue about. EBITDA is the easiest. Then your lender and your investors decide where the earn-out sits in the stack, and that answer belongs in writing too.
Why earn-outs end in arguments
An earn-out pays the seller later if the business hits a target after you own it, which means the seller is paid from numbers that you now control. Every disagreement comes from that one fact. You run the books, set the prices and decide the overhead. The seller can only read what you report.
Agree on the arithmetic now, while both sides still want the deal to close. A clause that says "EBITDA as reasonably determined by the buyer" is a lawsuit with a delay on it. Write the formula instead.
1. Pick a metric the seller can check
Revenue is the simplest earn-out metric, because the seller can trace it to invoices and bank deposits without arguing about a single cost you added after close. Its weakness is margin. You could grow sales at a loss and still owe the payment.
EBITDA tracks what you care about, profit, and it starts the most fights. Your management fee, your new hires, a shared accounting team and the cost of your next acquisition can all land on the acquired company's books. The seller will dispute each one. Gross profit sits in between, and it suits a business where the seller controls pricing and you control overhead.
Whatever you choose, name it once and define it in an exhibit. Three definitions get read three ways.
2. Attach a worked calculation to the agreement
Write that the earn-out is calculated under the same accounting principles the seller used for the historical statements, applied the same way, and then prove it. Attach an exhibit that runs last year's actual numbers through the formula, line by line, to the payment it would have produced. Both sides sign it.
That exhibit turns a future argument into a checklist. When the first year closes, your controller repeats the same steps with new numbers. The seller's accountant checks each line against the template. A disagreement is then about one line, never the whole method.
3. Keep separate books for the earn-out period
Integration is where earn-outs break, because the moment you fold the acquired company into your platform its revenue and costs blend with everyone else's. Keep a separate ledger or cost center for the business until the last payment is calculated. A roll-up buyer needs this more than anyone.
Then write what you may and may not do during the period. A seller will ask that you keep the business running, keep its customers, and fund it as planned. You will want room to run it your way. Agree on both lists, and add what happens if you sell the company before the period ends. Expect the seller to ask for the full earn-out to be paid at that sale.
4. Write the dispute path step by step
A dispute clause works when every step has a deadline and a named decision maker, so nobody can stall the payment by going quiet. You deliver the statement first, a set number of days after the period ends. The seller then gets the books and a set number of days to object in writing, item by item.
Anything not objected to is final. Then both sides negotiate the disputed items for a fixed window. Whatever is still open goes to an independent accounting firm named in the agreement, which decides only those items and only from the agreement's definitions. That process is cheaper than a lawsuit. It also ends on a date.
Decide set-off now as well. If you want the right to deduct an indemnity claim from an earn-out payment, the agreement has to say so, and the seller will negotiate hard against it.
5. Put the earn-out in its place in the stack
Your senior lender will want every earn-out payment to wait behind its loan, so expect a subordination agreement with the seller that blocks payment during a default or a covenant breach. Ask the lender how it counts the earn-out in its coverage tests before you sign the LOI. If the deal carries SBA 7(a) debt, ask the lender in writing whether it will accept an earn-out at all.
Cody Sechelski worked with Raises.com® on capital structure and lender sourcing, and closed the first acquisition of his Texas HVAC roll-up using an equity-light structure with seller participation. The capital came from a tournament across multiple capital firms, and the seller waited because the structure and the story held. His file says seller participation. It does not say earn-out, and neither client file here describes one.
The lesson carries anyway. Cody's warning is that the large majority of deals that reach a letter of intent never close. A loose earn-out term at the LOI stage is one more way to join that majority, because the lender and the seller find the gap months later.
Your investors read the earn-out as a claim on the same cash that pays their distributions. Ade worked with Raises.com® and closed two acquisitions with a philosophy centered on capital preservation and sustainable returns that are predictable. An uncapped earn-out is the opposite of predictable. Cap it, date it, disclose it in the PPM as a contingent obligation, and say in the operating agreement whether it is paid before distributions.
Revenue vs gross profit vs EBITDA earn-outs
| Question | Revenue | Gross profit | EBITDA |
|---|---|---|---|
| What the seller can trace | Invoices and deposits | Invoices plus direct costs | Every line on the income statement |
| Where disputes start | Revenue recognition timing and returns | What counts as a direct cost | Overhead, management fees and new costs added after close |
| Risk to the buyer | Paying for sales made at a loss | Paying while overhead grows | The lowest, if the definitions hold |
| Risk to the seller | The lowest | Costs reclassified as direct | Buyer costs that shrink the number |
| What the books must show | Sales of the acquired business, kept apart | Sales and direct costs, kept apart | A full income statement for the acquired business |
Frequently asked questions
How is an earn-out measured?
Against a metric and a target written into the purchase agreement, over a set period after close. Revenue, gross profit and EBITDA are the usual choices. An exhibit with a worked calculation shows exactly how the number is built.
What happens when the buyer and seller disagree on an earn-out?
The dispute clause runs: a written objection, a negotiation window, then an independent accounting firm decides the items still open. It works only when each step has a deadline. Without one, the next stop is court.
Does a senior lender let you pay an earn-out?
Usually yes, behind its loan and under a subordination agreement with the seller. Payments stop during a default or a covenant breach. Ask how the lender counts the earn-out in its coverage tests before the LOI.
What happens to an earn-out if the buyer sells the company?
Whatever the purchase agreement says, which is why the seller will ask for an acceleration clause. Under that clause, a sale before the period ends triggers the payment. Without the clause, the seller fights about it later.
Can a buyer deduct indemnity claims from an earn-out?
Only when the agreement grants a set-off right. Sellers resist it, so negotiate it with the earn-out and write the procedure down.
