How firms recognize referral fee revenue under ASC 606 when payment is contingent

The short answer for firms that receive referral fees

A referral fee paid only if a third party later closes and collects on its own deal is variable consideration under ASC 606. The firm estimates it, then applies the constraint: the estimate goes into revenue only to the extent it is probable that a significant reversal of cumulative revenue will not occur once the uncertainty is resolved (ASC 606-10-32-11). When payment depends on a referred company signing, its buyer paying and the counterparty collecting its own fee, that test often keeps recognized revenue at or near zero until those events happen.

This matters most to fractional CFO firms, outsourced accounting practices and advisory boutiques that receive referral fees on their own books, and to CFOs who close the books for clients that receive them. The conclusion is a judgment your auditor or reviewing accountant will test, so write it down.

This is general information, not legal, tax or financial advice. Confirm with your own counsel, tax adviser or professional body before acting.

Walking a contingent referral fee through the five steps

FASB has clarified Topic 606 since it was issued. ASU 2016-10, for example, refined the guidance on identifying performance obligations and on licensing without changing the standard's core principle. If your agreement promises more than an introduction, such as ongoing support while a deal is negotiated, step 2 deserves a closer look.

Why the constraint usually holds the revenue back

Topic 606 lists factors that make a revenue reversal more likely (ASC 606-10-32-12). A contingent referral fee tends to trigger several at once:

• Factors outside the firm's influence: the fee depends on decisions by the referred company, a buyer and the counterparty, none of which the firm controls.
• A long wait: the uncertainty may not resolve for months after the introduction.
• Limited experience: most firms have few comparable introductions on which to base an estimate.
• A broad range of outcomes: the fee could be nothing, or anything up to the cap.

The result is often a two-date pattern. The performance obligation is satisfied when the introduction is delivered, but revenue is recognized when the constraint lifts, typically when the counterparty confirms the fee is earned and payable. Booking a most-likely amount on the introduction date is the error to avoid.

One exception does not help here. Topic 606 has a separate rule for sales-based or usage-based royalties, but it applies to consideration promised in exchange for a license of intellectual property. A referral fee pays for an introduction service, so the general variable consideration guidance applies.

When does the constraint lift?

Each milestone reduces uncertainty; only the last ones remove most of it.

For a SourceX introduction the mapping is direct. Partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company. The reward becomes payable only after the buyer pays and SourceX receives its fee, and no reward is guaranteed; a lead, a meeting or a signed agreement alone does not trigger payment. That trigger is the same event the constraint analysis keys on. Because the cap is cumulative per referred company, track the remaining headroom per company rather than per deal. Payout conditions sit on the rewards page; the referral earnings calculator illustrates the published formula.

Record the fee, not the deal

A firm that introduces a company never controls the data being licensed or the license itself. Its revenue is the referral fee, never the value of the transaction it helped start. Topic 606's principal-versus-agent guidance points the same way: an entity that arranges for another party to provide goods or services records its fee or commission, not the gross amount.

Two presentation habits keep the books clean:

• Show referral fees as their own revenue line or account, not inside client billings.
• If the firm also bills the introduced company for advisory work, keep the two streams apart. They involve different customers, different contracts and different timing.

The referred company's revenue is a separate analysis

The company that licenses its data runs its own ASC 606 analysis, centered on the nature of the license. Deloitte's roadmap chapter on identifying the nature of a license explains the difference between a right to access intellectual property over the license period and a right to use it as it exists when granted, which is the seller's question, not the referring firm's. A fractional CFO who keeps the books for both the firm and the client should write two separate memos and never net one against the other.

Independence, disclosure and firm policy

Accounting treatment is only one question. A CPA firm that receives a referral fee should also check the AICPA Commissions and Referral Fees Rule (ET 1.520). The rule bars a member in public practice from taking a commission for recommending a product or service to a client for whom the firm also does attest work (an audit, a review, certain compilations, or an examination of prospective financial information), and it requires any referral fee that is allowed to be disclosed to the client (AICPA Code of Professional Conduct). State boards of accountancy can be stricter, so check your state's rule too.

Fractional CFO firms that are not licensed CPA firms should still check engagement letters and internal policies on outside fees. The fractional CFO partner page explains how these firms fit the program.

Documentation checklist for the file

• The signed agreement, with the fee formula, cap and payment trigger.
• The date of each introduction and the evidence for it.
• A constraint memo naming the factors that apply and explaining why the estimate is or is not in the transaction price.
• At each reporting date, the status of every referred company and whether any event has lifted the constraint.
• Payment confirmations from the counterparty, matched to the revenue entry.
• Client disclosures and, for CPA firms, the attest-relationship check.
• Any disclosures your reporting framework requires for variable consideration.

Illustrative quarter-by-quarter pattern

Illustrative and fictional: a fractional CFO firm, called Firm A here, introduces a client company in the first quarter. At the first and second quarter-ends it records no revenue, because the company has not signed and the constraint applies in full. In the third quarter the company signs a license; Firm A updates its memo but still records nothing, because the buyer has not paid. In the fourth quarter the counterparty confirms the buyer has paid and the reward is payable. Firm A records revenue and a receivable for the confirmed amount, then clears the receivable when the cash arrives.

Next step

If your firm plans to make introductions, set up the constraint memo template before the first one, then register as a partner. Firms still deciding which entity should receive the fee can read whether to take referral fees through an LLC.
