A referral partner agreement pays someone for sending business, not for doing the work itself, and most of the time that is a contract any two businesses can write in an afternoon: define a qualified referral, set a fee, pay it when the deal closes. The part worth checking before signing is a short list of industries where paying for a referral is not simply a commercial choice but is restricted, capped, or banned outright by federal or state law. Real estate settlement services, the practice of law, real estate sales themselves, and parts of healthcare each have their own rule, and the penalties in at least one of them are criminal.

Outside those industries, a referral partner agreement is ordinary contract drafting, and the only real design decisions are the fee structure and how a referral gets tracked and credited. This is general information, not a review of one specific deal; a lawyer should confirm which, if any, of the restricted categories applies before fees start changing hands.

How referral fees are usually structured

Three structures cover most referral partner agreements. A flat fee per qualified referral pays a set amount once a referred lead meets an agreed definition, such as booking a paid appointment or signing a contract; it is the simplest to administer and the easiest to dispute, since everything turns on what "qualified" means. A percentage of the first transaction pays the referrer a share of whatever the referred customer actually spends on their first purchase or contract, which scales the fee to the deal size but pays only once. A recurring percentage of ongoing revenue, common in software and subscription referral programs, pays the referrer a share of what the referred customer keeps paying over time, often for a capped number of months or for as long as the customer stays.

Whichever structure is chosen, the agreement needs to settle attribution before the first referral arrives: what counts as a referral (a named introduction, a tracked link, a discount code), the lookback window between the referral and the sale that still counts, and what happens when two partners both claim credit for the same customer. A clause that leaves attribution to "good faith" is a clause that gets argued over the first time a referral is worth real money.

Where paying for a referral is restricted

Industries that restrict referral fees

Industry What is barred Rule
Real estate settlement services Any fee, kickback, or thing of value paid for referring business incident to a federally related mortgage loan's settlement (title insurance, escrow, appraisal and similar services) Real Estate Settlement Procedures Act section 8, 12 U.S.C. section 2607; criminal fine up to $10,000 and up to a year in prison, plus treble damages to the overcharged party
Legal services A lawyer paying anything of value for a recommendation of the lawyer's services, with an exception for a nonexclusive, disclosed reciprocal referral agreement with another lawyer or a nonlawyer professional ABA Model Rule of Professional Conduct 7.2(b); states adopt their own version, so the exact wording varies
Real estate sales commissions Paying a real estate commission, in most states, to a person who is not a licensed real estate agent or broker State real estate license laws; a flat finder's fee not tied to negotiating a specific transaction is treated more leniently in some states, so this one is genuinely state by state
Healthcare paid by federal programs Offering or paying any remuneration to induce referrals of services or items reimbursable by Medicare, Medicaid, or another federal health care program Anti-Kickback Statute, 42 U.S.C. section 1320a-7b(b); a federal criminal law with its own set of narrow safe harbors

None of this touches a referral partner agreement between two ordinary businesses outside these categories: a landscaping company paying a property manager a flat fee for sending jobs, or a software company paying a consultant a recurring percentage for referred subscriptions, is an ordinary commercial arrangement with no special statute attached. The restrictions above exist because the underlying transaction is either paid for by a third party who is not at the table (an insurer, a federal health program) or is gatekept by a license the referrer does not hold.

Referral partner versus reseller

A referral partner introduces a prospect and steps aside; a reseller or channel partner buys the product or service and resells it, or sells under its own contract and takes a margin rather than a fee. The distinction matters because none of the restrictions above apply to a reseller in the same way: a reseller is a party to the underlying sale, not a person paid to produce it, so a real estate brokerage's unlicensed marketing vendor cannot be paid a referral fee for sending buyers, but a licensed brokerage can still buy advertising services from that same vendor at an ordinary commercial rate. A channel partner agreement is usually its own, longer document covering pricing tiers, territory, and support obligations, closer in shape to a distribution contract than to the referral clause below.

Sample referral fee clause 
Referral Fee. Company shall pay Referrer a fee equal to [10%] of the Net Revenue collected by Company from a Qualified Referral within [twelve (12)] months after the date of the introduction, payable within thirty (30) days after the end of each calendar quarter in which Net Revenue is collected. A "Qualified Referral" means a prospective customer that (a) was not an existing customer of Company in the preceding twelve (12) months, (b) is introduced by Referrer through the tracked referral link or code assigned under this Agreement, and (c) enters into a paid agreement with Company within ninety (90) days of that introduction. This Agreement does not make Referrer an agent, employee, or partner of Company, and Referrer has no authority to bind Company to any transaction.

The ninety-day attribution window and the twelve-month payout window are the two numbers worth negotiating hardest; a shorter attribution window favors the paying company, and a longer one favors the referrer. The last sentence matters on its own: without it, a referral partner who starts representing the company's terms to customers can create exactly the kind of apparent authority a true business partner would have.

A referral program that grows past a handful of partners starts to look like a joint venture in its own right, particularly once the partners begin cross-promoting or sharing customers rather than simply introducing them, and the compensation question starts to resemble revenue share versus equity more than a one-off fee. The agreement is worth revisiting at that point rather than stretched to cover a relationship it was not written for; how to write partnership proposals covers what to put in front of a referral partner being asked to become something closer to a real partner.
