An earn-out can bridge a valuation gap, but it can also move the dispute from signing to the years after closing. Deferred payment creates a different question: whether an agreed amount will actually be paid. Buyers and sellers should distinguish the two mechanisms and document measurement, control and credit risk separately.
Choose a metric that can be audited
Define the business, measurement period, accounting policies and calculation formula. Revenue, EBITDA and customer retention create different incentives. Address intercompany charges, exceptional items, currency conversion and acquisitions made during the period. Attach worked examples for ordinary and downside cases. A familiar metric without detailed definitions can become ambiguous when the buyer integrates the target into a larger group.

Allocate control over the result
Decide which operating commitments are appropriate during the earn-out period. Consider budgets, product discontinuation, related-party transactions and changes to accounting systems. The buyer needs room to manage the business, while the seller needs protection from conduct that defeats the agreed calculation. Avoid vague obligations to maximise the earn-out; identify specific actions, consent rights and information access.

Separate payment security from performance
For fixed deferred consideration, assess the payer’s credit and available security. Consider the practical value of a guarantee, escrow or other agreed protection, including release conditions and expiry. For contingent amounts, define when the obligation crystallises. A large headline purchase price offers limited comfort if the payment entity has no assets and the seller has no effective remedy.

Create a focused dispute process
Specify who prepares the calculation, what records are supplied, how long objections may be raised and which issues go to an accounting expert. Separate pure calculation disputes from contractual breaches or fraud allegations. Define the expert’s mandate and appointment fallback. Align the mechanism with governing law and jurisdiction or arbitration provisions so parallel procedures do not produce incompatible outcomes.

Coordinate tax, employment and transaction terms
Review whether payments are genuinely purchase consideration or linked to continued employment or services. Obtain tax advice on the actual structure and recipient rather than relying on the label earn-out. Align set-off rights, indemnity claims and payment deadlines so the same loss is not counted twice. Preserve access to records after a founder leaves; the calculation should not depend on continued goodwill.

Frequently asked questions
Is deferred payment always an earn-out?
No. A fixed amount paid later differs from consideration contingent on future performance.
Can EBITDA be used without a detailed definition?
It is risky; accounting choices and integration can change the result.
Should an accountant decide every dispute?
No. Define which issues are accounting questions and which require legal resolution.
