Collect a testimonial before the van leaves the driveway

A customer is most grateful in the ten minutes after the heating comes back on. Leave a card with a QR code, send one short email that evening, and ask before you photograph their home.

  • Wording for a leave-behind card with your QR code
  • A same-day follow-up email
  • A plain request to photograph the finished work

Thanks for having us in today.

If Technician did a good job, scan the code and tell us in a sentence or a 30-second video. It helps neighbours choose who to let into their home.

The problem, solved

Why trades jobs end without a testimonial, and how to change that

Situation 1 of 4

The tech is already at the next job

Asking is nobody’s job on site, and the office calls days later when the relief has faded.

How StoryProof solves it

The office sends one StoryProof email request the same evening, so the ask lands while the heating is still a fresh relief and nobody has to phone round.

    “That’s [the boiler repair] done. If you’re happy with it, there’s a code on the card. A line or two about today really helps us. Thanks for having me.”

Prompts

Prompts that get a specific story

Put two of these on your StoryProof form. A specific job story is more convincing than “great service”.

Emergency call-outs

  • What had gone wrong, and how worried were you?
  • How quickly did we get there, and what happened next?

Leave out

  • Asking them to rate competitors

Planned installs and upgrades

  • What made you choose us for the job?
  • How did the team leave your home afterwards?

Regular cleaning or servicing

  • What do you no longer have to think about since we started?
  • Who on the team do you look forward to seeing?

Run it with StoryProof

  • Cards or invoice templates you can print a QR code on
  • A StoryProof workspace
  1. 1

    Make a form with two prompts

    Customers answer from their phone with a video, an audio note or a few typed words, with no app.

  2. 2

    Print the QR code on the card or invoice

    Technicians hand it over at the door. The same link can go in the evening email.

  3. 3

    Approve and tag by service and area

    Nothing is public until you approve it. Tags such as “boiler”, “emergency” or a town name let each service page show the right stories.

  4. 4

    Show them where people decide

    Add approved stories to service pages, or share your hosted Wall of Love link in quotes and estimates.

What happens next: Thank the technician by name when their customer’s story goes up. It makes asking at the door feel normal.

Before you start

Keep it fair

What this does not cover, and what to check on your side. Better to know now than after launch.

  1. 01

    Ask everyone, not only happy faces

    Hand the card to every customer. Picking who gets asked based on how the job went skews your proof and can break review platform rules.

  2. 02

    No addresses in photos or text

    Remove house numbers and street names before publishing anything. A town name is usually enough.

  3. 03

    Email and QR only

    StoryProof sends requests by email. If you text customers from your own phone, paste the link in yourself.

  4. 04

    Tenants and landlords differ

    The person who let you in may not be the one paying. Ask whoever saw the work, and do not describe a tenant’s home without their agreement.

FAQ

Questions people ask

Short answers to what usually comes up next.

When should a plumber or HVAC tech ask for a testimonial?

At the door when the job is finished and working, with a card to scan, then once more by email that evening. Later than a day or two and the moment has passed.

Can older customers leave a testimonial without an app?

Yes. They scan the code or tap the link and type, talk or record in the browser.

Can I use photos of the job?

Ask first, keep a note of the answer, and leave out anything that identifies the home or the people in it.

Should technicians get a bonus for testimonials?

If you offer one, reward the asking, not the result. A bonus tied only to glowing answers pushes technicians to pick who they hand the card to.

What if the customer is out when the job finishes?

Leave the card with the invoice and rely on the evening email. Say in it what was done, since they did not see the work happen.

Still have a question? Ask the StoryProof team or book a demo.
