How to Create a Referral Program for Your Small Business

A referral program is a written set of rules for rewarding people who send you customers. To create one, decide who can refer, what they get, the moment the reward is earned, how you'll track each referral, and what referrers should disclose. Keep the rules short enough to fit on one page, and work out what each referral costs you before you announce it.

This page is about designing the program. For how to ask clients for introductions, with or without a formal program, see how to get referrals for your business. For collecting reviews and quotes, see how to collect customer testimonials.

Decide who can refer

Start narrow. Your current customers are the obvious group, because they've seen your work. You can add partners who serve the same customers, such as an accountant for a bookkeeper, later. Write down whether staff, family members and existing customers' own businesses count.

Choose the reward

Pick one reward and use it for everyone:

• Credit on their next invoice: keeps the reward inside your business and brings the referrer back.
• A fixed gift or payment: simple to explain, but it costs cash.
• A reward for both sides: a credit for the referrer and a discount for the new customer, so the introduction feels like a favor to both.

Whatever you choose, ask an accountant how to record it, especially for cash rewards.

Decide when the reward is earned

Tie the reward to a moment you can check, not to a promise. One option is "when the new customer's first invoice is paid". That rules out referrals that never turn into work, and it gives you a clear date to pay the reward.

Write one page of rules

Your rules page should answer, in plain words:

• who can refer and who can be referred;
• what the reward is and when it's paid;
• how a referral is recorded, such as the new customer naming the referrer when they book;
• what happens if two people refer the same customer;
• how you'll end or change the program.

Tell referrers what to disclose

If referrers talk about you in public, such as in a social post or a review, the reward can matter to the people reading it. In the US, the FTC's guidance on its Endorsement Guides (checked October 31, 2026) says that "if there's a connection between an endorser and the marketer that a significant minority of consumers wouldn't expect and it would affect how they evaluate the endorsement, that connection should be disclosed clearly and conspicuously." It adds: "Even an incentive with no financial value might affect the weight or credibility of an endorsement and would need to be disclosed." Put a line about disclosure in your rules, and ask a lawyer if you're unsure how it applies.

Worked example: what a referral costs you

Sample figures: a design studio's average first project is 1,500.00, and after direct costs it keeps 40% of that, or 1,500.00 × 0.40 = 600.00. The program gives the referrer a 100.00 credit and the new customer 100.00 off their first invoice, so each paid referral costs 100.00 + 100.00 = 200.00. That leaves 600.00 minus 200.00 = 400.00 from the first project, before any repeat work. If your numbers leave nothing, lower the reward or tie it to a larger first purchase.

Track every referral

Keep one list with the referrer, the new customer, the date of the first paid invoice and the date you gave the reward. Review it every quarter: who refers, which rewards get used and whether referred customers stay. Change one thing at a time so you can see what made the difference.

Where Billed fits

To check that a referred customer's first invoice is paid, Billed's invoice software page says: "Invoice reports show which invoices are paid, partially paid or past due, and you can see who owes you money and send them a payment reminder." To apply a credit, Billed's features page says: "You can easily give discounts to your clients on your invoices."

Mistakes to avoid

• Paying rewards before the new customer has paid you.
• Rules that change from one referrer to the next.
• No written record of who referred whom.
• Leaving disclosure to chance when referrers post about you.

When this guide isn't for you

If you sell through a large affiliate network or a partner channel with contracts, use those agreements instead. This page doesn't give legal or tax advice; ask a lawyer or an accountant about your program.
