When is the best time to ask a customer for a referral?

Right after the job is finished

This is when the result is fresh and the customer can see what you've done. If they're clearly pleased, a short, friendly ask fits naturally into the conversation as you wrap up.

When they pay or receive the invoice

The invoice is something every customer looks at. A single line with your referral link reaches everyone, including those you didn't get to speak to in person.

When they leave a good review or send thanks

A kind review or message tells you they're happy to speak up for you. Replying with a thank-you and your link is a gentle, well-timed next step.

A few weeks later, for some services

For work where the benefit shows over time, like a garden that grows in or a boiler that's running well through the cold, a short follow-up a few weeks later can work well. It also reminds people you exist.

When not to ask

• While something is still being fixed or a complaint is open
• Before the customer has seen the finished result
• Several times in quick succession

There isn't one perfect moment for every business. Try a couple of these and notice which ones lead to referrals for you.

In short

Start with the end of the job and the invoice, since you already have both. Add a follow-up later if your type of work suits it.
