Most happy customers never leave a review — not because they don't want to, but because finding your business on Google Maps and tapping through to the review box takes too many steps for something they weren't planning to do. A direct link removes that friction.
Get your review link first
In Google Business Profile, look for "Get more reviews" — it gives you a direct link that opens the review box immediately, skipping the search step entirely. That's the URL you'll turn into a QR code, not your general Maps listing link.
Where to put the QR code
Right after the moment of satisfaction: the receipt, a table tent at checkout, a thank-you card in a delivery bag. Putting it at the entrance instead — before anyone has experienced anything — gets far fewer scans.
One honesty rule
Never filter who gets shown the QR code based on how happy they seemed, and never offer a discount in exchange for a review — that violates Google's policies and can get reviews removed or your listing flagged.
Test the link before printing
Test-scan it yourself first — a broken review link is worse than no QR code at all, because it wastes the one moment a customer was willing to help.
