A QR code on your invoice, business card, or van takes your customer directly to your Google review page. One scan, one tap, review posted. Here's how to set it up.
Why QR codes work for tradespeople
You finish a job. The customer is happy. But asking "can you leave us a Google review?" face-to-face feels awkward. A QR code removes the friction — it's on your invoice, your business card, a sticker on your van. The customer scans it when they're ready, on their own time.
No app install — the customer's phone camera is enough
No typing — no searching for your business name on Google
No forgetting — the QR code is right there on the document they keep
Add &action=write to the end (this pre-opens the review form)
Paste the URL into any free QR code generator (e.g. qr-code-generator.com)
Download the QR code image
Print it on invoices, cards, stickers
Problem with DIY: You get a static QR code with no tracking. You'll never know how many customers scanned it, whether they actually left a review, or what rating they gave. And if a customer is about to leave a 1-star review, nothing stops them.
Option 2: FiveStarPing (smart QR code)
FiveStarPing generates a branded review page for your business. The QR code points to this page, which:
Shows your business name and a friendly prompt
Displays in the customer's language (30 languages supported)
Asks the customer to rate their experience first
If they rate 4-5 stars → redirects to Google review page
If they rate 1-3 stars → sends the feedback to you privately (negative interceptor)
You get a review page, a QR code you can print anywhere, and protection from negative reviews — all on the free plan.
Where to put your QR code
Invoices — every customer gets one, perfect placement
Business cards — hand it over after the job
Van/vehicle signage — passive collection while parked at a job
Email signature — every email you send includes it
Receipts — if you give printed receipts
Follow-up texts — include the link (not the QR) in SMS
QR code + SMS: the combination that works best
The QR code catches customers who are ready to review right now. SMS catches the ones who meant to but forgot. Together, they cover both scenarios. FiveStarPing handles both — QR on the free plan, SMS on Pro ($15/month).
