Review Links and QR Codes on Invoices and Trucks

The best moment to ask for a review is the minute the house starts cooling again. The homeowner is relieved, the tech is still in the kitchen, and the experience is fresh. An hour later they're back to their day. A week later they've forgotten your name.

A review link and a QR code make that moment easy to act on. This guide covers where to put them, how to print them so they scan, and the rules that keep your reviews from disappearing.

Step 1: Get the real link from Google

Don't build the link by hand or copy it from a browser bar. Use the one Google gives you:

1. Sign in to your Business Profile on a computer.
2. Select Read reviews, then the option to get more reviews.
3. Copy the link, or right-click the QR code and save the image.

Google notes that "reviews QR codes can only be generated on a computer browser, not on mobile devices" (Google Business Profile Help). Google itself suggests sharing the link on receipts and in thank-you emails.

If you'd rather build the link from your Place ID, or want a printable code in a size and style you choose, the Google review link and QR code generator does both.

Test the link on two phones, one Android and one iPhone, signed in and signed out. Customers need a Google Account to post a review (Google Business Profile Help), so the signed-out test shows you what they'll hit first.

Step 2: Put it where the job ends

Think about where a customer's attention is at the end of a visit. Ranked roughly by how close they are to that moment:

1. The invoice or receipt. It's the last thing they look at. Add a short line near the total: "How did we do? Scan to leave a Google review." If you make invoices with the invoice generator, put the code in the notes area.

2. A leave-behind card. A small card the tech hands over with the paperwork: your logo, the code, and one sentence. It works even when the invoice is emailed later.

3. The maintenance sticker. Many shops put a sticker on the furnace or air handler with the service date and phone number. A small review code on the same sticker reaches the customer each time they change the filter.

4. The follow-up text or email. A link is better than a code on a screen; nobody wants to scan their own phone. Send it the same day. The review request message generator has templates for both.

5. The truck. Rear doors work better than side panels, because people see them while parked behind you. Expect few scans from a moving truck. Don't ever encourage someone to scan while driving.

6. Your email signature and website. Low effort, steady trickle. The email signature generator can add the link to every email you send.

Step 3: Print it so it actually scans

Most failed QR codes are print problems, not code problems:

• Contrast. Dark code on a light background. Avoid printing on dark truck paint without a white box behind it.
• Quiet zone. Leave a clear margin of blank space around the code. Don't crowd it with text or borders.
• Size for the distance. A code on a card is scanned from inches away; one on a truck door from several feet. Print a test at the size you plan and try scanning it from the distance a real person would stand.
• Finish. Glossy laminate can glare under sunlight or a flashlight. Test before ordering a batch.
• Words next to it. Always add a sentence saying what the code does. People are cautious about scanning unknown codes.

For other codes, like one that opens your booking page, the QR code generator makes styled PNG or SVG files.

Step 4: Know the rules

This is where well-meaning shops lose reviews.

Ask everyone, not just happy customers. Google's policy says merchants must not "selectively solicit positive reviews from customers," and must not "discourage or prohibit negative reviews" (Maps User Contributed Content Policy). The practice of sending happy customers to Google and unhappy ones to a private form is often called review gating, and it falls under that rule.

No incentives. Google prohibits offering "payment, discounts, free goods and/or services" for reviews, and that includes rewards for changing or removing a negative review (same policy). So no "$20 off your next tune-up for a review," no gift card drawings for reviewers.

No pressure on site. The same policy says merchants should not require or pressure customers to leave reviews while on the premises. Handing over a card is fine. Standing over someone until they post is not.

No staff quotas. Google lists "requesting that staff solicit a certain number of reviews" as not allowed. Track how often techs ask, not how many reviews they produce.

The FTC has rules too. The FTC's rule on consumer reviews, announced in August 2024, bans fake reviews, incentives conditioned on a particular sentiment, undisclosed reviews from company officers and managers, and suppressing negative reviews through "unfounded or groundless legal threats, physical threats, intimidation" (FTC). On gating specifically, the FTC's Q&A on the rule says the rule "does not contain a specific prohibition" against it, but warns the practice could still violate the FTC Act (FTC). Reviews from family members and employees are also a conflict of interest under Google's policy.

Step 5: A script techs will actually say

Keep it short and the same for every customer:

"Thanks for having us out. If you have a minute later, this card has a link to our Google reviews. Honest feedback helps us, good or bad."

That's it. No promise of a reward, no "only if you're happy."

What to do with the reviews you get

• Reply to every one, briefly. Google suggests keeping replies "professional, polite, short and simple" and avoiding the same thank-you for everyone (Google Business Profile Help).
• For a negative review, acknowledge it, don't share private details, and offer to talk by phone.
• If you quote reviews on your website, use real ones with permission and don't imply a cherry-picked few are typical. Our guide on what an HVAC website should include covers how to show them honestly.

A website is the natural home for your review link, your hours and everything else on the card.
