The strangest year of a founder’s life isn’t the year they sell the company. It’s the year after, if part of the price is still in play. You wake up in the same town, drive to the same office, greet the same team, and manage the same client relationships, except the company belongs to someone else, your remaining money depends on a number you negotiated eight months ago, and the person who now approves the budget can make decisions that move that number. Welcome to the earnout year: employee, stakeholder, and hostage to a metric, all at once.
Earnouts are neither trick nor gift. They’re a bridge over a real disagreement (the buyer won’t pay today for growth you swear is coming; you won’t discount for risks you swear are imaginary), and something like them appears in a large share of MSP deals. Whether the bridge holds depends almost entirely on how it was built, so this post covers both halves: what the year actually feels like, and the terms that decide whether it ends with a wire or a dispute.
What the year is actually like
The first surprise is psychological. Every operational choice now has two readings: what’s right for the business long-term, and what it does to your number this measurement period. Most days those agree. The days they don’t are corrosive in a way sellers don’t anticipate. The buyer wants to migrate clients to their PSA in Q3 (right for integration, disruptive to the revenue your earnout measures). They want your best engineer on a platform project (great for the company, invisible to your metric). You’d have absorbed a client’s rocky quarter with patience when you owned the place; now every churned logo has your name on the invoice, literally.
The second surprise is how much depends on decisions you no longer control. Your earnout rides on the performance of a business unit inside someone else’s company, and their integration choices (repricing, tool changes, how the team is handled) move your number for better or worse. A buyer can torpedo an earnout without a single bad intention, just by running their standard playbook. This is why the diligence you did on the buyer’s track record matters more when an earnout is involved, and why “may I speak with a seller whose earnout finished?” is the single best question in your process.
The third surprise is the accounting. Come measurement day, “EBITDA of the acquired business” turns out to contain a dozen judgment calls: does the earnout calculation absorb corporate overhead allocations? The new group insurance rates? The migration costs the buyer chose to incur? Vague purchase agreements answer none of this, and every unanswered question defaults, structurally, toward whoever controls the ledger. Which is not you.
Terms you can live with, negotiated while you still have leverage
Everything protective happens before signing, in the LOI and purchase agreement, so here’s the checklist that separates livable earnouts from litigation generators.
Pick a metric you can still influence, and the simpler the better. Revenue or gross-margin targets beat EBITDA targets for sellers, because EBITDA absorbs the buyer’s cost decisions (allocations, salary changes, tool spend) that you can’t control. Retention-based earnouts (paid for keeping clients) are simpler still, and often the fairest bridge when client concentration is what drove the earnout in the first place.
Define the calculation like an accountant, not a diplomat. The agreement should name the accounting standards, list what’s excluded (corporate allocations, integration costs, intercompany charges), and include a worked example with real numbers. If the earnout section of your purchase agreement has no arithmetic in it, it isn’t finished.
Get operating covenants. Language obligating the buyer to run the business consistent with past practice during the earnout period, or at minimum, not to take actions primarily intended to reduce earnout payments, plus specific protections for the things your metric depends on (pricing authority, your role’s scope, sales resources). Absolute protection doesn’t exist, but silence is consent to anything.
Caps, floors, and slopes. All-or-nothing cliffs (“100% payout at $2M revenue, nothing below”) manufacture disputes at the boundary. Sliding scales with a floor pay something for partial performance and take the knife-fight out of the last dollar. Shorter is better too: a 12-to-24 month earnout is livable, while a four-year one is a sentence.
Audit rights and a referee. You want the contractual right to review the calculation with supporting detail, and a named dispute path (typically an independent accountant whose call is final) so a disagreement costs weeks, not years.
And step zero, before all of it: minimize the earnout. Every dollar moved from contingent to cash at close is a dollar that can’t be argued about later. Take the slightly smaller certain number over the slightly larger maybe. Sellers almost never regret that trade; they frequently regret the reverse.
The honest bottom line
A fair earnout, precisely drafted, with a buyer whose references check out, is a legitimate way to close a valuation gap, and plenty of them pay in full without friction. Our own view, having sat on the buying side: earnouts work best when they’re small, short, simple, and nearly unnecessary, because the real work happened earlier, in pricing the business honestly and structuring the deal so neither side needs the bridge to carry much weight. If a buyer’s offer leans heavily on a long, complex earnout measured in numbers they control, that’s not a compromise. That’s the negotiation continuing after closing, on their field, with their referee. Price it accordingly, or keep talking to other buyers.
