Here is the answer up front: an earnout is not price, it is a bet, and the buyer holds the cards after closing. When a buyer offers $1 million but only $700,000 arrives at closing, with the rest "earned" later based on performance, you have not sold for $1 million. You have sold for $700,000 plus a wager on numbers the buyer will control, measure, and report. Some earnouts pay in full. Many pay nothing. The difference is rarely luck; it is the drafting.
What an Earnout Is, and Why Buyers Propose One
An earnout is contingent consideration: part of the price is deferred and paid only if the business hits agreed performance targets after closing. You get cash at closing plus a formula, usually tied to revenue, gross profit, or EBITDA (earnings before interest, taxes, depreciation, and amortization, a rough proxy for operating cash flow) measured over one to three years.
Buyers give three reasons for proposing one. Only one is good for you.
First, bridging a valuation gap. You think the business is worth more because a big contract is about to land; the buyer will not pay today for growth that has not happened. An earnout lets both of you be right. Before you agree to bet the difference, pressure-test your own number against what your business is actually worth.
Second, shifting risk. The buyer worries your customers leave when you do, so the earnout becomes their insurance against overpaying. That moves the risk of the buyer's ownership onto you, the person who no longer owns the business.
Third, financing the deal with your own money. A buyer who cannot fund the full price proposes to pay you later out of the business's own future profits: the company you built buys itself from you, on your unsecured credit. The deal literature's canonical warning is the seller who took a third in cash and a third deferred, then discovered the deferred money would come from the sold company's next two years of profits. If the structure includes a promissory note too, read my piece on seller financing; both instruments are credit extended to the buyer, and both should be capped as a share of the total price.
Earnouts usually first appear as one friendly sentence in the letter of intent, and that sentence is where the fight starts: metric, window, covenants, and dispute process are all still undrafted.
The Fundamental Problem: Your Money, Their Scoreboard
Every earnout shares one structural defect: after closing, the buyer runs the company, keeps the books, allocates the expenses, and prepares the earnout statement. Your payout depends on numbers computed inside systems you no longer control, by people who owe you money. That is not an accusation of bad faith; even an honest buyer makes hundreds of ordinary judgments that each nudge the metric. And you are selling a business once in your life against a buyer who structures deals for a living.
The worst case is the seller who walks away at closing. If you exit on day one and control nothing that drives the metric, the earnout is close to a free option for the buyer: they pay only if things go well under their own management. One veteran seller-side author's instruction for performance-linked deferred money is blunt: be pessimistic.
The Five Classic Ways Sellers Get Burned
1. Expense allocation games
The buyer charges the company a "management fee," allocates corporate overhead, books restructuring costs against it, or charges deemed interest on capital the buyer itself put in. None of this changes how the business is really doing; all of it shrinks an earnings-based metric. Well-drafted deals ban overhead allocations entirely, or permit only direct services billed at cost.
2. Starving the business
The buyer cuts marketing, freezes hiring, and lets the metric drift below the hurdle, then invests properly the day after the measurement window closes. The cure is incentive design: the buyer keeps a share of the upside above the hurdle, so growing the number pays better than managing it down, over a window long enough that starvation hurts the buyer too.
3. Integration destroys the baseline
The buyer folds your company into their existing operation, merges the customer lists, and consolidates the books. Six months later, nobody can even compute your metric, because "your" revenue no longer exists as a separate number. The cure is a covenant that the company keeps its separate corporate existence and separate books through the earnout period. Without it, the metric is unmeasurable, and unmeasurable means unpaid.
4. Control disputes
Many earnouts assume the seller stays on through the measurement period. Then the buyer overrides your pricing, reassigns your best employee, or vetoes the expansion your projections depended on; the metric misses, and each side blames the other. The agreement must say what you control, what the buyer controls, and what happens to the earnout if they fire you or box you out.
5. The buyer sells the business mid-earnout
Two years into your three-year earnout, the buyer flips the company, or the buyer's lender takes the keys after a default. Your claim is subordinated paper in someone else's restructuring, and the new owner has no relationship with you. The fix is an acceleration clause: on a sale, a change of control, or an uncured payment default, the remaining earnout becomes due. Standard forms do not include this. You have to ask.

Picking the Metric: Why Revenue Beats EBITDA
If you take one drafting rule from this article, take this one: push the earnout metric as high up the income statement as you can. The higher the line, the fewer buyer judgments stand between the business's real performance and your payout.
Revenue is the top line: total sales before any costs. It is the hardest number for a buyer to quietly reshape, because a management fee, an overhead charge, or a new bookkeeping policy never touches it. Gross profit (revenue minus the direct cost of delivering the work) sits one level down: still fairly resistant, but the buyer's decisions about supplier pricing and job costing start to leak into your number.
EBITDA sits near the bottom, below every operating expense, and this is where sellers get hurt. EBITDA sounds objective. It is not; it is a negotiated number, riddled with judgment calls about revenue recognition, expense classification, and compensation, and after closing every one of those calls belongs to the buyer. The same normalization arguments the buyer's accountants used to grind your price down during diligence will reappear at each measurement date.
Sometimes you cannot avoid an earnings metric, because the buyer reasonably refuses to pay for unprofitable revenue. Then the EBITDA definition has to be armored: accounting policies frozen at closing, no buyer allocations except direct services at cost, and a negotiated list of what can be charged against the number. Some triggers dodge the problem entirely: an earnout keyed to an observable third-party event (a contract renewal, a regulatory approval) pays on facts the buyer cannot cook.
The Protective Terms I Negotiate
When a client's deal includes an earnout, these are the terms I push for. No deal gets all of them; the negotiation is about which matter most.
A covenant to operate consistently. The buyer runs the business in the ordinary course, consistent with past practice, and keeps it a separate entity with separate books through the earnout period. This is the foundation; without separate books, nothing else is even measurable.
Caps on what can be charged against the metric. No management fees, no overhead allocations, no restructuring costs, no deemed interest on buyer-infused capital, except as expressly negotiated. The buyer's form will quietly permit these; strike them.
Information and audit rights. The buyer will produce monthly reporting for its own lenders; you want contractual access to the same information, plus a fixed deadline for each earnout statement and the right to have your accountant inspect the books if you object.
A sliding scale and shared upside, not a cliff. An all-or-nothing target invites manipulation right at the line; a payout scaling between a floor and a cap pays something for a near miss. And if performance above the target splits between you and the buyer, the buyer keeps a reason to grow the number. Alignment beats policing.
Acceleration on sale or breach. If the buyer sells the business, undergoes a change of control, or defaults on a payment, the remaining earnout comes due. Where the buyer is a thin shell entity, I also want security behind the promise: a personal or parent-company guarantee, or a repurchase right on default.
A dispute channel designed in advance. Decide now, in the purchase agreement, how earnout fights get resolved: direct negotiation, then confidential mediation, then binding arbitration or an independent accountant, with a rule about who pays. The one channel you do not want is the default: public litigation, years later, from a position of no leverage.
One more protection lives outside your own contract: the buyer's bank covenants can block earnout payments outright when the company underperforms, which is exactly when you are most nervous. Ask for an express carve-out in the buyer's financing permitting earnout payments, and ask to see the buyer's leverage before agreeing to a large contingent piece. A buyer who refuses to show you is telling you something.
When to Refuse the Earnout and Price the Business Flat
Sometimes the right answer is no. I steer clients toward a flat price, even a lower one, in three situations.
You are leaving at closing. If you retire the day the deal closes, you control nothing that drives the metric. That earnout is a lottery ticket someone else scratches. Push the value into the fixed price or a secured note, and get the business ready to command that price; my exit-ready LLC guide covers what to fix before a buyer sees your books.
The earnout is standing in for money the buyer does not have. Then you are not bridging a valuation gap; you are the lender of last resort, unsecured and unpaid for the risk. Either price the credit properly with security and a real return, or find a buyer who can pay.
The targets are set off the buyer's own projections. An earnout that pays only if the buyer's own forecast is exceeded is option value, not price. Deals like that happen at the bottom of broken sale processes, when the seller has run out of alternatives. Do not evaluate the offer as if that money were real.
One caution: buyers read earnout acceptance as a signal of confidence in your own numbers, so a flat refusal needs a prepared explanation (retirement, diversification) or the buyer hears doubt and cuts the fixed price. Refusing is also easier when you are not counting on this one buyer. If an unsolicited buyer approached you, remember they are a repeat player running a familiar playbook, and the seller with a credible alternative is the one who can say no.
Comparing Offers: Earnout Dollars Are At-Risk Dollars
Do not compare headline numbers; compare certain dollars. With invented numbers again: a "$1 million" offer paying $650,000 at closing with a $350,000 EBITDA earnout may be worth less than a flat $800,000 offer, once you discount the contingent piece for the buyer's control of the metric, the buyer's credit risk, and the cost of fighting about it. Cash at closing is the price; the earnout is upside on top of it.
That is the single test I give every seller: would you still sign this deal if the earnout never pays a dime? If yes, the earnout is a bonus. If no, it is load-bearing, and you are carrying the buyer's risk for free.
The earnout is one clause in a bigger transaction. For how an Illinois sale actually closes, see my guide to selling your LLC in Illinois and the rest of the LLC hub.

Frequently Asked Questions
Push for revenue, the top line, because it is the hardest number for a buyer to reshape with expense allocations and accounting judgments. Gross profit is second best. EBITDA is the most dangerous choice, because it absorbs every buyer decision about overhead, management fees, and expense classification. If you cannot avoid EBITDA, the definition must freeze accounting policies at closing, bar buyer overhead allocations, and list what can be charged against the number.
Generally no. If you exit on day one, you control nothing that drives the metric, and the earnout functions as a free option for the buyer: they pay only if things go well under their own management. Push the value into the fixed price or a secured note instead, and frame the refusal as retirement or diversification so the buyer does not read it as doubt about your numbers.
Usually nothing good, unless your purchase agreement says otherwise. Your claim becomes subordinated paper in someone else's transaction, and the new owner has no relationship with you. The protection is an acceleration clause: on a sale of the business, a change of control, or an uncured payment default, the remaining earnout becomes due. Buyer forms do not include acceleration; your attorney has to negotiate it in.
You can, but litigation is the worst channel for an earnout fight: public, slow, expensive, and useless against a buyer with no money to pay a judgment. Design the dispute process in the purchase agreement instead: audit rights, a deadline for each earnout statement, a window to object, and a tiered clause sending disputes to negotiation, then confidential mediation, then arbitration or a neutral accounting firm.
