Earnout Escrow Setup for SaaS Deals: Amounts, Release, Disputes

An earnout escrow is a pot of money the buyer funds at or after closing and a neutral escrow agent holds until the earnout metric is met or missed. You set it up in three places: the purchase agreement (what triggers payment), the escrow agreement (who holds what and when it releases), and the metric definition (how revenue or retention is measured). Get those three to agree with each other and most earnout fights never start.

This guide is for AI SaaS founders selling and buyers acquiring, mostly in the US. It covers when escrow is worth it, how to size and release it, what to write about metrics, and the tax and dispute points that catch people out.

TL;DR

• An earnout is deferred price that depends on future performance. Escrow is a holding mechanism. They solve different problems, and you can combine them by funding the earnout in advance.
• Escrow for an earnout makes sense when the buyer’s ability to pay later is uncertain or the deferred amount is large relative to the price.
• Define the metric (ARR, revenue, retention) to the dollar, with accounting rules, measurement periods and a named accountant for true-ups.
• Ask for staged releases, and write down who pays escrow fees, who owns the interest for tax and where notices go.
• On AIExchange.club, listings are free, the success fee is a flat 10% with no monthly fees, and deals close through escrow with standardized contracts. The marketplace is for AI SaaS businesses only.

Earnout vs. escrow: two tools, two jobs

People mix these up because both involve money sitting somewhere after a deal is signed.

An earnout is a purchase agreement provision that makes part of the price payable to the seller based on the acquired business’s performance after closing. The American Bar Association’s Business Law Today separates it from ordinary deferred price (effectively seller financing) and from post-closing adjustments (a fix for a closing-condition difference). Its size generally reflects how far apart the parties were on what the business is worth.

A classic M&A escrow is different. Per the ABA’s Escrow 101 article, closing proceeds are set aside with a third party to cover future obligations, mainly buyer losses from breaches of the seller’s representations and warranties, and returned to the seller if not needed. It is a risk-allocation and collection device, not a performance bonus.

So in a SaaS deal you can end up with two separate pots:

An “earnout escrow” is the third option: the buyer deposits the maximum earnout with the escrow agent up front, and the agreement says how it releases to the seller or returns to the buyer. For the deal-level view of earnouts themselves, see our guide to earnouts in SaaS deals.

When to put an earnout in escrow

Not every earnout needs one. A $20,000 micro-SaaS with a $3,000 earnout paid at month six by a buyer who has already funded the deal may be fine on a signed promissory term. Escrow earns its cost in these cases:

• The earnout is a big share of the price. Practitioner guidance puts the contingent share at 15 to 30 percent or more of total consideration, with terms typically running one to three years. The bigger the share, the more the seller is lending to the buyer.
• The buyer is a new entity or a first-time acquirer. A seller cannot easily evaluate a fresh holding company’s credit. A law firm’s guidance on securing earnouts lists escrowed funds, parent guarantees and bank letters of credit as ways to give the seller a dedicated source of payment.
• The buyer has senior debt. If a lender ranks ahead of the seller’s earnout, escrowed funds sit outside that fight. The same source suggests sellers negotiate escrow or other security where earnout payments are subordinated.
• The metric is simple and the measurement window is short. A 12-month ARR test is easy to escrow. A three-year multi-metric formula ties up cash for a long time, and a buyer will resist.

Buyers have their own reason to like it: a funded escrow makes the earnout credible, which can persuade a seller to accept a lower upfront payment. See our piece on financing a SaaS acquisition for how that cash fits with the rest of the capital stack.

Step 1: Define the metric before you size the escrow

The escrow amount is the maximum earnout. The earnout amount depends on the metric. Start there.

Common measures are revenue, gross income, net operating income, or non-financial milestones such as a product launch, per Davis Wright Tremaine’s 2026 earnout guidance. Schwabe’s M&A guidance adds operational benchmarks such as new-customer counts, and notes that missing the benchmark can eliminate or reduce the payment.

For a SaaS business, that usually means one of these:

1. Recurring revenue (MRR or ARR). Define it: do annual prepayments count when invoiced or ratably? Are usage overages in? Are refunded or charged-back payments netted out?
2. Gross or net revenue over a period. Simple, and sellers tend to prefer revenue because it is harder for a buyer to shrink through discretionary spending or expense allocations, according to the Davis Wright Tremaine piece.
3. Retention. Net revenue retention or logo churn at a fixed date. Our NRR guide shows the formula so both sides compute it the same way.
4. Operational milestones. A migration to a new model provider, a launched feature, or a transferred integration. Holland & Knight’s October 2026 guidance says such milestones should be objective, auditable and explicit about partial or late achievement.

The same Holland & Knight guidance warns that EBITDA has no universally accepted definition, so agreements should spell out revenue, EBITDA, GAAP or historical accounting treatment, overhead allocations, intercompany charges, one-time items and adjustment rules. For a solo-founder AI product, that translates to a short list worth writing down: how API and inference costs are treated, whether the buyer’s other products can be bundled with the acquired one, and whether revenue from existing customers moved to a different plan counts.

A worked example

Say a buyer acquires an AI writing tool for $120,000 total. They agree $90,000 at closing and a $30,000 earnout, 25% of the price, tied to ARR at month 12.

• Baseline ARR at closing, as verified in diligence: $96,000.
• Tier 1: ARR of $96,000 to $105,999 pays $10,000.
• Tier 2: ARR of $106,000 to $115,999 pays $20,000.
• Tier 3: ARR of $116,000 or more pays $30,000.

The escrow is $30,000, the maximum. At month 13 the buyer delivers an ARR statement, the seller has a review window, and the agent releases the tier amount to the seller and any balance back to the buyer. These numbers are an illustration, not a benchmark or an AIExchange.club offer.

Tiers beat a cliff. One dollar below the target should not erase the whole payment, and a cliff gives the buyer an incentive to delay a signup or the seller to pull one forward.

Step 2: Size, fund and release the escrow

Amount. For an earnout escrow, fund up to the maximum payable amount if you want full protection. A partial deposit, say half, is a common compromise: it signals good faith without locking up all the buyer’s cash. Be clear which number you picked and why.

For the separate indemnity escrow, benchmarks exist. The ABA reports a typical reserve of 5 to 10 percent of purchase price. A 2026 mid-market guide from Bochner PLLC puts it at 5% to 10% of enterprise value without representation-and-warranty insurance, often for 12 to 18 months with staged releases. Those figures describe larger deals; a small SaaS sale will often negotiate lower, so treat them as the top of the range you may be asked to defend against, not a rule.

Funding. Fund at closing, not “on the first of the following month.” An unfunded escrow is a promise.

Release schedule. Write each release as a trigger plus a deadline, for example: buyer delivers the ARR statement within 30 days after month 12; seller has 30 days to object; undisputed amount releases within five business days of the end of that window. Sellers should ask for staged releases so that proceeds come out as risk periods expire, a point both Bochner and Fasthoff Law Firm stress. Fasthoff also recommends a reserve policy so that one disputed claim cannot freeze the whole balance.

Housekeeping the agreement must cover. The ABA says to specify how funds are invested, when and to whom they are distributed, who owns them for tax purposes, where notices go, and the escrow fees. Fasthoff notes that fee sharing is set by the agreement, so decide it rather than inherit a default. In practice, splitting fees evenly is common and simple.

Step 3: Protect the seller while the buyer runs the product

After closing, the buyer controls pricing, marketing, roadmap and support. That is the core earnout risk. Davis Wright Tremaine lists the protections sellers can ask for:

• An ordinary-course operating covenant.
• Commitments on staffing, marketing spend or capital investment.
• Separate books and records for the acquired product.
• Access to financial records and relevant personnel.
• A defined dispute process.

For a small AI product, make the covenants concrete: keep the product live under its current name, keep the pricing page within an agreed range, do not sunset the legacy plan, maintain model quality, and do not migrate customers into another product of the buyer’s during the period. Holland & Knight’s view is that precision in formulas, accounting rules and objective evidence costs less than litigating ambiguity.

Buyers need protection too. Ask for the right to change the tech stack when a model provider changes terms or pricing, because AI products depend on third-party APIs. Our AI SaaS due diligence guide covers which dependencies to verify before signing, and the APA guide for sellers shows where these clauses sit in the document.

Step 4: Plan for a missed target, a resale or a dispute

Missed target. Say plainly what happens: tier payout, zero, or a catch-up if a later period beats the number. State where the unreleased escrow goes, normally back to the buyer.

Resale of the product. The agreement can provide for acceleration if the buyer sells the business during the earnout period, per Davis Wright Tremaine. Without it, a buyer who flips the product can leave the seller chasing a new owner.

Calculation disputes. The usual path is review, objection, negotiation, and referral of unresolved items to an independent accounting firm. Be careful what you hand that accountant. US courts treat expert determination as distinct from arbitration, and an accountant’s role is generally limited to discrete accounting tasks and true-ups, not legal questions of contract interpretation. A 2026 Delaware decision, Georgia Security Solutions v. NewCBN, also held that a sole-recourse clause limited the parties to the remedies in the earnout provisions, not only to the accountant procedure. Lesson: define terms such as ARR in the contract itself, so no one has to ask an accountant to decide what they mean. Have a lawyer in your state review the dispute clause.

Tax points to raise with your adviser

This is where a CPA earns the fee. An American Bar Association tax article explains that post-closing escrow and earnout payments can bring a seller into installment-sale treatment when at least one payment arrives after the closing tax year, with some statutory exceptions. Each installment generally includes both basis recovery and taxable gain, so purchase-price allocation, contingent-payment valuation, timing, character and interest all need coordinating.

Two more flags: Fenwick & West has noted that Section 280G golden parachute rules can reach earnout payments if they are characterized as compensation for services, so keep a founder’s employment terms separate from the purchase price. Whether you structure the deal as an asset or a stock sale also changes tax and liability; see our asset vs. stock sale comparison. Talk to a US tax adviser before you sign, not after.

What we think

We see the same pattern in small AI SaaS deals: buyers and sellers argue about the future because they cannot verify the present. A seller says the product is growing, a buyer sees a wrapper around a model API that anyone could rebuild. An earnout bridges that gap, but only when the metric is easy to audit.

Our view: use the smallest earnout that closes the gap, measure it on verified recurring revenue, keep the window to 12 months for small products, and if it is more than a token amount, fund it into escrow. For a micro-SaaS, a long multi-metric earnout costs more in lawyer hours and bad feelings than it ever recovers. If the gap is small, a price adjustment is usually cleaner than a contingent payment.

We also think the cleanest setup is the one the buyer and seller can both read in one sitting. Standardized contracts and a fixed pipeline remove a lot of the drafting where deals go sideways. We do not publish earnout-specific templates or buyer and deal statistics here, so treat the worked example above as a teaching case, not our data.
