How to set up a referral program for your contracting business

Ask for referrals at the moment a customer is happiest, make the reward simple and paid fast, and write every referral down so you know who sent it. Keep the referral reward completely separate from any review request, because Google bans paying for reviews and the FTC expects people who get a reward for posting to say so. Then add a few realtors, property managers and other trades who send work both ways.

Why a referral program beats hoping for word of mouth

Most owners get referrals; few run a program. A program asks every happy customer on purpose, pays the same reward every time, and keeps a list.

The pull of word of mouth is easy to see in the numbers. Jobber’s 2026 Home Service Trends Report, as summarized for cleaning businesses, found 64% of leads came from repeat customers and 60% came from referrals, well ahead of Facebook, lead sites and Google Search [1]. That’s vendor research on one trade, but it matches what most plumbers, painters and lawn crews will tell you about their best customers: they came from somebody who already trusted the company.

A program won’t replace your Google Business Profile or your ads. It does lower what you pay for each new job, because the only cost is a reward you pay after the work is sold. If you’re working out what that is worth against paid channels, the marketing budget guide shows how to compare them on cost per booked job.

When to ask: the five moments that work

Timing matters more than the reward. A customer who just watched you fix a problem is in a giving mood; the same person three weeks later has moved on. Build the ask into these moments so nobody has to remember it:

1. At the final walkthrough. The remodeler showing off a finished bathroom, the roofer walking the homeowner around a clean yard, the electrician flipping on new recessed lights. Say it out loud while they’re smiling.
2. Right after an emergency fix. The HVAC tech who got heat back on at 9 pm or the plumber who stopped a leak has earned more goodwill than any marketing could buy. Ask before you leave the driveway.
3. When they pay. Put one line about the referral reward on the invoice or the payment receipt. It reaches every customer with zero extra effort.
4. At a recurring visit. Lawn, cleaning, pest and pool customers see you every week or month. Ask after the third or fourth visit, once they trust the routine, not on day one.
5. When they compliment you. A text that says “the house looks amazing” is an invitation. Thank them, then ask.

Ask for referrals and reviews on different days. A review request goes out a day or two after the job; the referral ask happens in person and on the invoice. Mixing them muddies both, and as the rules section below explains, a reward must never be tied to a review.

What to give: cash, gift cards, credits or donations

Pick one reward, state it plainly, and pay it only when the referred customer’s job is done and paid. Here are the usual options and where each one fits:

Many shops make it two-sided: the referrer gets a reward and the new customer gets something too, like a waived trip charge. That gives your customer an easy line: “Tell them I sent you and they’ll get $50 off.”

How big? Size the reward against what a new customer is worth to you, not against what a competitor offers. The table below is an illustrative example, not a benchmark:

Taxes. The IRS’s 2026 instructions for Forms 1099-MISC and 1099-NEC put the reporting threshold at $2,000 for most payments, and they list referral fees as nonemployee compensation [4]. A homeowner who sends you two jobs a year won’t get near that, but a property manager or another contractor who refers often might. Keep a W-9 on file for repeat referrers and ask your accountant how to handle gift cards and credits.

The rules: reviews, online posts and disclosure

A referral reward is fine. Problems start when the reward gets tangled up with reviews or public posts.

• Never pay for a Google review. Google’s Maps content policy lists offering incentives, “such as payment, discounts, free goods and/or services,” in exchange for posting a review as fake engagement [3]. That covers a gift card for a five-star review and a discount for changing a bad one.
• Don’t make a reward depend on a positive opinion. The FTC’s guidance says you can’t condition an incentive on a review being positive [2].
• Tell referrers who post online to mention the reward. If a customer shares your company in a neighborhood group or on Facebook and they know they’ll get paid for it, the FTC expects that connection to be disclosed whenever it would affect how much readers trust the post [2]. Plain words work: “They give me $50 if you hire them.”
• Put the disclosure where people will see it. The same FTC guidance says “#ad” at the start of a post is about as good as “Ad:”, and that a disclosure buried inside a long run-together hashtag may be missed [2].
• Train your heavy referrers. The FTC expects companies with networks of people promoting them to explain the disclosure rules and check on what those people post [2]. For a contractor that usually means a short note to the handful of partners who send you work often.

A simple way to stay clean: your referral card and texts never mention reviews, and your review requests never mention rewards.

Partners: realtors, property managers and other trades

Customers refer a few times a year. Partners can refer every month. These are the relationships worth building:

With professionals, lead with service, not cash. Many agents and managers care more about a contractor who makes them look good than about a fee, and some work under brokerage or employer rules on accepting payments, so ask first. Sending work both ways is usually the cleanest arrangement.

1. List ten agents, managers or trades who already work in your area. Your past jobs are the best clue: who was the agent on that pre-sale repair?
2. Reach out with something useful, like a one-page price range sheet for common repairs or a promise to look at inspection items within two business days.
3. Do the first job extra well and send a short report with photos to the partner as well as the homeowner.
4. Check in once a quarter with a text, not a sales pitch.
5. Send work back. A partner who never gets a referral from you will stop sending them.

Copy-ready scripts and texts

Change the names and rewards, keep them short, and use the same words every time so your crew can say them too.

In person, at the walkthrough: “I’m glad it came out the way you wanted. Most of our work comes from people like you telling a neighbor. If you know anyone who needs a hand, give them my card. When they hire us, we’ll send you a $100 check as a thank-you.”

Line on the invoice or receipt: Know someone who needs [service]? Send them our way. When their job is done, you get [reward] and they get [new-customer offer]. Just have them mention your name.

Text a week after the job: Hi [name], it’s [your name] from [company]. Hope the [new water heater / furnace / deck] is treating you well. If a friend or neighbor ever needs [service], we’d be glad to help, and we send [reward] for every referral who becomes a customer. Thanks again.

Thank-you text when a referral calls: [Name], your neighbor [first name] just called us because of you. Thank you. We’ll take good care of them, and your [reward] goes out as soon as their job is finished.

Partner intro text: Hi [name], I’m [your name] with [company]. We do [service] around [area] and handled [job] for one of your clients on [street]. If your clients need [service] before or after a sale, I can look at inspection items within two business days and send a written quote you can forward. Happy to send work your way too.

Online-post note for referrers: If you share us online, please add a line like “They give me a thank-you if you hire them” so readers know. We appreciate it.

How to track referrals so nobody gets missed

The fastest way to kill a referral program is to forget to pay someone. Tracking takes five minutes a week with a spreadsheet or the notes field in your job software.

1. Ask every new caller how they heard about you. Put the question in your phone script and on your website form. If they say “a neighbor”, ask which one.
2. Log it the same day. One row per referral: date, new customer, who referred them, job, reward owed.
3. Mark it when the job is paid. That’s when the reward becomes due.
4. Pay within a week and send the thank-you text above. Fast payment is what makes people refer a second time.
5. Review the list monthly. Count referrals, booked jobs and rewards paid, and note your top referrers by name.

A unique code per referrer (like their last name) on a card helps when the new customer forgets who sent them. Once a quarter, sort by referrer and send your top three a handwritten note. They are your best salespeople. For how referrals fit with reviews, ads and mail, see the full contractor marketing guide.
