Do I Need a Contract for an Affiliate or Referral Partner?

Someone offers to send you clients for a cut. Or you find someone with an audience who'll promote your offer for a percentage of every sale.

It feels like free money. No payroll, no ads, no risk — they only get paid when you get paid.

So you agree over a DM. Maybe an email. "20% of whatever closes, sound good?" "Sounds good."

I spent 20 years litigating business disputes, and I want you to understand what you just did. You didn't create a low-risk revenue channel. You created a business partner with no rules, no boundaries, and no exit — who is now out in the world saying whatever they want with your brand attached, and who has a claim to your money that neither of you has defined.

Yes, you need a contract. Here's exactly what goes wrong without one, and what the agreement has to say.

What actually goes wrong with a handshake referral deal?

You fight about what a "referral" is. They send you a name. The name doesn't convert. Eight months later, that person comes back through your ads and buys. Is that their commission? They think so. You don't. Nobody wrote down what triggers a fee, so now a judge decides — and judges resolve ambiguity against whoever wrote the deal, which in a text-message deal is both of you.

You fight about how long they get paid. They referred a client once, two years ago. That client is now on their fourth retainer. Are they still owed 20%? Forever? A handshake has no clock in it, so their answer is always yes.

They say something to close the sale that you have to live with. This is the one that actually gets people sued. Your affiliate promises your program will double someone's revenue. They imply a guarantee you never made. They post a fake-scarcity countdown, or an earnings claim, or a testimonial they made up. The buyer sues — and they sue you, because it's your product, your money, and your brand. "My affiliate said that, not me" is not a defense that ends the case. Under FTC rules, you are responsible for what people say when they're promoting your business for money.

They promote you next to something toxic. Your offer, running alongside a crypto scheme or a supplement with wild health claims, on a channel you'd never want your name near.

They use your brand however they like. Your logo stretched and recolored. A lookalike domain. Google ads bidding on your own trademark, so you're now paying a commission on customers who were already searching for you by name.

And then they leave — with your client list. No confidentiality clause, no non-solicit. They now go start something competitive with a list of everyone you introduced them to.

Every one of those is a lawsuit I've either handled or watched happen. Not one of them requires a bad actor. They happen between people who liked each other and never wrote anything down.

What does an affiliate or referral agreement actually need?

A precise definition of a qualified referral. Not "someone they send." Define it: a named prospect, submitted in writing or through a tracked link, who was not already in your pipeline, who closes within a defined window. That last part is the whole ballgame — a referral has to have an expiration date.

A commission structure with an end. What percentage, of what number. Gross or net — say which, because "20% of the deal" and "20% of what you keep after the platform fee and the refund" are very different numbers. When is it paid — on invoice or on cleared funds. And for how long: first purchase only, twelve months, life of the client. Pick one and write it down.

A clawback for refunds and chargebacks. If the client refunds in week two, that commission comes back. Without this clause, you paid a percentage on revenue you no longer have.

Compliance rules with teeth. This is the clause that keeps you out of a courtroom. Require clear and conspicuous disclosure of the paid relationship on every promotion — that's an FTC requirement, not a suggestion. Ban earnings claims, income guarantees, health claims, fabricated testimonials, and fake urgency. Require pre-approval of creative if the stakes justify it. Then add an indemnification clause: if they break the rules and it costs you, they pay for it. Whether you can actually collect from them is another question — which is why the prohibition matters more than the indemnity.

A tight trademark license. They get a limited, revocable, non-exclusive right to use your name and logo only to promote your offer, in the form you provide, on approved channels. No trademark bidding in paid search. No lookalike domains. No implying they're an employee, a partner, or an owner. And it terminates the day the agreement does.

Independent contractor status, stated plainly. They're not an employee, not a partner, not a joint venture, and they have no authority to bind you or negotiate on your behalf. Write it, because someone will eventually claim otherwise.

Confidentiality and non-solicitation. They see your pricing, your pipeline, and your clients. Say what they can't do with that — during the deal and after it.

Termination, either side, for any reason, on notice. With an immediate-termination trigger for a compliance breach. And say what happens to pending commissions when it ends, because that's the fight.

The one that costs the most

If you take a single clause away from this, take the compliance one.

Every other problem on this list is a money fight. Annoying, expensive, survivable. But the moment someone with a financial incentive starts making claims about your product to strangers, you have handed a stranger the keys to your legal exposure — and the regulator and the plaintiff both come to your door, because you're the one who profited.

Affiliates are the cheapest way to grow and the cheapest way to get sued. It's the same clause that decides which.

Frequently asked questions

Is a verbal or DM referral agreement enforceable? Often, yes — which is the trap. People assume "we never signed anything" means there's no deal. A court may well find one, and then it gets to decide what the terms were based on your texts, your emails, and two people's memories. You don't avoid a contract by not writing it. You just lose control of what it says.

What's the difference between a referral agreement and an affiliate agreement? A referral partner introduces you to a specific person and steps back — the fee is usually one-time, and there's little to no public promotion. An affiliate actively markets your offer to an audience, usually through a tracked link, on an ongoing basis. The affiliate relationship carries far more risk, because they're speaking publicly about your business, which is why it needs the compliance and trademark clauses.

Do affiliates legally have to disclose that they're getting paid? Yes. The FTC requires clear and conspicuous disclosure of any material connection between an endorser and the business — and enforcement can land on the business, not just the promoter. Put the disclosure requirement in the contract, and monitor whether it's actually happening.

Can I be held responsible for what my affiliate says? Yes. That's the part founders don't see coming. You can face liability for deceptive claims made by people promoting your product for compensation, and the buyer who feels misled sues the company that took their money. A contract that bans specific claims, requires disclosure, and lets you terminate immediately is your first and best line of defense.

The bottom line

You wouldn't hire a salesperson with no rules on what they're allowed to promise. An affiliate is a salesperson with no rules on what they're allowed to promise — you just didn't think of it that way, because you're only paying them on results.

Write it down. Define the referral, cap the commission, control the claims, license the mark, and keep the right to end it.
