How to Vet a Referral Partner Before You Start Sending Them Customers

Your referral is your reputation. When you tell a homeowner "you should call this electrician, they do great work," you are putting your name on the line. If that electrician shows up late, does sloppy work, or overcharges the customer, the homeowner does not blame the electrician — they blame you for recommending them. One bad referral can undo years of trust you have built with a customer.

This is why vetting your referral partners is not optional. It is the most important step in building a referral network, and most contractors skip it entirely.

Start with Their Work

Before you send anyone a single referral, see their work firsthand. Visit a job site where they are currently working. Look at the quality of their craftsmanship. Watch how they interact with the homeowner. Notice whether the site is clean and organized. These details tell you everything you need to know about how they will treat your customers.

If you cannot visit a job site, ask for photos of recent completed work. Any contractor who takes pride in their work will have a portfolio ready to share. If they cannot show you examples of their work, that is a red flag.

Check Their Responsiveness

The fastest way to destroy a referral relationship is to send a customer to someone who never calls them back. Before you partner with someone, test their responsiveness. Call their business number during work hours. Send them a text. Email them. Note how long it takes them to respond. If they take 48 hours to get back to you — a fellow contractor — imagine how long they will take to respond to a customer referral.

Responsiveness is the single best predictor of referral success. A contractor who responds within two hours to a referral will close the job at twice the rate of one who waits two days.

Verify Their Credentials

This is basic but critical. Verify their contractor license is current and in good standing. Check their insurance — they should carry both general liability and workers compensation. Look them up on the BBB and your state's registrar of contractors. A single complaint on file is not necessarily a dealbreaker, but a pattern of complaints is.

In Arizona, you can verify licenses through the Arizona Registrar of Contractors at roc.az.gov. It takes two minutes and tells you everything you need to know about their licensing and complaint history.

Start Small

Never go all-in on a new referral partner. Send them one referral first. Follow up with the customer afterward to ask how it went. Did the contractor show up on time? Was the work quality good? Was the pricing fair? Was the customer satisfied? One test referral tells you more than any interview or reference check.

If the first referral goes well, send a second. Then a third. Build the relationship gradually. By the time you have sent five referrals and gotten positive feedback on all of them, you have a proven partner you can trust with your reputation.

Use Trust Scores

Referly's trust score system was designed specifically to solve the vetting problem. A contractor's trust score reflects their actual referral behavior — how responsive they are, how many referrals they complete successfully, how many active partnerships they maintain, and how long they have been consistently performing. It is a reputation metric built on real data, not self-promotion.

When you browse potential partners on Referly, the trust score gives you an immediate signal of reliability. A contractor with a 70+ trust score has a proven track record of being a good partner. Join Referly and start building partnerships with contractors you can trust.
