Two questions on a sticker at the register.
Customer pays, sees the sign, scans on their way out. Star rating, one open text, done. You see it the moment the next customer walks up to the counter.
Q01Where should I place the QR code?
Where customers naturally pause. Checkout counter, fitting room, exit door. At a register, eye-level beside the card reader works well.
Q02How do I get customers to scan it?
"How did we do? Scan to tell us." Don't over-engineer with incentives. People who have something to say will scan. People who don't, won't. That's fine.
Q03What should I ask?
Star rating plus one open-ended question. Under 20 seconds. Most actionable feedback comes from the open-ended one.
Q04How do I respond to negative feedback?
Optionally ask for email. When a complaint comes in, follow up directly. "Here's what we're doing to fix it" often turns a complaint into loyalty.
Q05Can I track feedback by location or department?
Yes. Separate polls per location, per register, per department. Dashboard shows them side-by-side. CSV per location for accountability.
Q06Is feedback really anonymous?
Yes unless you ask for it. No name field, no email collection by default. Honesty goes up.
