Founder Earnouts That Pay: Metrics You Control and Disputes You Win
Sep 17, 2025
A seller’s field guide to designing earnouts that are achievable, auditable, and actually paid
Earnouts look generous in a term sheet and then vanish in the SPA footnotes or in post close integration. The usual culprits are vague metric definitions, buyer controlled levers, accounting policy drift, and cliffs that turn a near miss into a zero. The fix is design, not luck. Treat the earnout like a product you are building: define it clearly, instrument it, and protect it with simple rules you can enforce.
Essential taxonomy in plain English
-
Earnout: Additional purchase price paid if agreed performance metrics are achieved after closing.
-
Measurement period: The time window used to test the metric, often 12 to 36 months.
-
Metric family: What you are measured on. Examples include revenue, ARR, contribution margin dollars, EBITDA, or specific customer or product milestones.
-
Cliff vs slope: A cliff pays all or nothing at a threshold. A slope pays proportionally across a band. Slopes reduce dispute risk.
-
Stand alone vs consolidated: Whether your metric is calculated on the business as if it were independent, or inside the buyer’s platform. Stand alone is safer unless tracking is robust.
-
Set off: Whether the buyer can reduce earnout payments for unrelated claims or indemnities. Sellers prefer a hard bar on set off or a narrow cap with escrow.

First principles for a seller friendly earnout
-
Choose metrics you can actually steer. Favor inputs and outcomes your leadership team controls day to day.
-
Write the math, not just the words. Put the formula in the SPA with an example calculation and a sample report.
-
Keep the lens narrow. One or two metrics with clean definitions beats five that invite interpretation.
-
Use slopes, not cliffs. Graduated payments across a band turn small disagreements into small dollars.
-
Document policy stability. “Same accounting policies and materiality thresholds as last audited period” keeps the goalposts fixed.
-
Protect against the two big risks. Buyer actions that depress your metric, and allocation choices that bury your economics in someone else’s P and L.
Smart metric design by business model
Software and recurring revenue
-
Primary metric: ARR growth or net revenue retention with a defined ARR formula that excludes multi year invoice timing effects.
-
Backstops: Gross margin percent inside a band, logo retention, and a cap on discount erosion.
-
Carve ins: Credit for migrations, product bundling that keeps the same customer spend, and price increases inside guardrails.
-
Carve outs: M&A and divestitures, extraordinary items, and buyer mandated price cuts outside agreed guardrails.
-
Disclosure: Cohort tables, expansion and churn drivers, and treatment of prepaid and deferred revenue spelled out.
Product and distribution
-
Primary metric: Contribution margin dollars by SKU family or channel, not just top line.
-
Backstops: Price realization and returns rate within bands, with inventory obsolescence policy frozen to prior audits.
-
Carve ins: Mix upgrades that raise contribution even if units are flat.
-
Carve outs: Forced channel changes, house brand substitution, or platform wide promotions you do not control.
Services and projects
-
Primary metric: Revenue recognized from signed backlog plus new bookings conversion, or gross profit dollars with a minimum quality of earnings test.
-
Backstops: WIP and unbilled receivable rules, standardized milestone acceptance, and change order governance.
-
Carve outs: Buyer imposed staffing freezes or rate cuts that would have failed your pre close deal desk.
The control rights that make it real
Operational covenants convert promises into protection.
-
Run rate freedom: Buyer will not take actions primarily intended to avoid the earnout, including starving proven demand channels or reallocating qualified leads away from the business.
-
Pricing guardrails: Any material price changes outside agreed bands require mutual consent or an earnout adjustment equal to the lost contribution.
-
Budget and capacity: Reasonable access to approved headcount, media spend, and tooling required to pursue the earnout plan.
-
Commercial carve outs: M&A, product sunsets, or channel moves that would materially affect the metric trigger a true up or an agreed recast.
-
Reporting rights: Monthly reporting pack with the exact tables used to compute the metric, plus reasonable access to underlying records.
-
Policy freeze: Same accounting policies and materiality thresholds used in the latest audited financials unless both parties agree in writing.
The math, written in the document
Replace prose with formulas and examples.
Example slope for contribution dollars
-
Band A: 90 to 100 of target pays linearly from 50 to 100 percent of the tranche
-
Band B: 100 to 120 pays linearly from 100 to 150 percent of the tranche
-
Above 120 capped at 150 percent, with an aggregate earnout cap stated in dollars
Example ARR definition
ARR equals the sum of annualized contract values for active, non cancelable subscriptions at period end, excluding one time fees, usage above committed levels, and any contracts with payment delinquent over 60 days unless cured in 30. Expansion and contraction are measured relative to prior period ARR for the same cohort.
Example EBITDA guardrail
EBITDA for earnout purposes equals operating income plus depreciation and amortization, excluding non recurring items listed on Schedule X and the effects of IFRS 16 or ASC 842, unless those were applied in the last two audited periods.

Avoidable traps and clean counters
-
Cliffs that zero you out for small misses
Use slopes with bands and a modest cap. -
Buyer controlled costs
Define the cost base and prohibit overhead allocations that did not exist pre close unless agreed. -
Accounting policy drift
Freeze policies and materiality. Changes require mutual consent. -
Platform integration without tracking
If consolidation is required, include stand alone tracking for earnout metrics with independent review. -
Unlimited set off
Bar set off, or cap it to escrowed amounts with a narrow list of claim types. -
Late or opaque calculations
Require a standard calculation package within a fixed number of days after period end, with interest on late payments. -
M&A cannibalization
Exclude acquired revenue from targets or give credit for displacement that would have been captured pre close.
Reporting pack that prevents disputes
Ask for the same artifacts a buyer will use in diligence. Then hard code them into the SPA exhibits.
-
Metric dictionary with formula, data sources, and example calculation
-
Revenue and margin waterfalls from list to pocket economics
-
Cohort tables and pipeline progression by stage and source
-
Price realization and discount distribution by band and reason code
-
Returns, credits, and dilution history with policy citations
-
Inventory roll forward and E and O policy where relevant
-
Reconciliation from management reports to the GL with a data lineage note
If the report cannot be produced monthly, the metric is not ready for an earnout.

Dispute proof mechanics
-
Audit rights: Seller gets reasonable access to books and records relevant to the metric, with a defined data room and timeline.
-
Cure period: Buyer delivers the calculation package; seller has a fixed window to object; parties then confer.
-
Independent expert: If unresolved, a neutral accounting firm rules within 30 days, bound by the SPA definitions and exhibits only.
-
Payment timing and interest: Earnout payments due within a set period, with stated default interest if late.
-
No double dip: Items normalized out of EBITDA or revenue in QoE cannot be simultaneously used to reduce the earnout metric.
-
Public holidays clause: Deadlines shift to the next business day to avoid technical misses.
How to talk about this at LOI
Keep it short and specific. LOIs that say “earnout to be mutually agreed” invite re trading later. LOIs that state the metric, the band, the slope, the cap, basic control rights, and the policy freeze set expectations and shorten diligence.
One paragraph that travels
“An earnout of up to 20, payable over two annual periods, tied to stand alone ARR growth and contribution margin dollars, each paid on a linear slope across agreed bands, with no cliffs. Accounting policies and materiality follow the latest audited financials. No set off other than escrowed amounts. Buyer will not take actions primarily intended to avoid the earnout. Detailed definitions, example calculations, and reporting schedules to be attached to the SPA.”
Founder FAQ
Should I accept an EBITDA earnout
Only if cost allocations are frozen and controllable, and you have clear authority over the levers that move the number.
Can I get paid if the buyer integrates me
Yes, if stand alone tracking is required, or if a recast mechanism credits you for revenue or margin you created that moved into another P and L.
What size cap is normal
Enough to make the stretch worth it, but not so large that it invites conflict. Many sellers anchor the cap as a percent of base price with a slope that avoids cliffs.
Can I combine metrics
Yes, but keep it to two, with a weighting that reflects your control, and guardrails that prevent gaming one at the expense of the other.
Bottom line
Earnouts pay when the design is simple, the metric is within your control, the math is in the document, and the governance is strong enough to survive integration. Treat the earnout as a product with a spec, a telemetry pack, and a service level. Do that, and you will spend your post close energy meeting goals, not litigating definitions.
