Add a review prompt to your receipts
About 15 minutes per till · 4 steps
Square, Zettle and SumUp don't let you add a free image to a printed receipt. You have two things to work with: the logo slot and a custom message line.
- 01
Know what each card machine allows
Square: printed-receipt logo (black and white only) plus a custom message. SumUp: logo upload plus a custom message. Zettle: a custom text line. Its logo is for digital receipts, not printed ones.
- 02
Make the QR image
A scannable code has to go in the logo slot. On your Manage page, click Download PNG. Save it as a square, pure black-and-white image, at least 15 mm wide on the printed receipt. Add a short caption such as "Scan to review".
NoteReceipt printers print in black and white only. Don't use colour or grey, or the code may not scan. - 03
Upload it, or set your message
Square: Settings → Account & Settings → Business → Branding. Create a theme, upload the printed-receipt logo (at least 400×200 px, black and white) and add your message. Square — customise receipts. SumUp: back office → Configuration → Your Business → Edit. Turn on "Logo on receipt", upload, then Update. SumUp help centre. Zettle: my.zettle.com → Account & Settings → Receipt settings. Type your review line into the "More information" field. Zettle — customising receipts.

Test it
Ring up a 1p sale, refund it, and scan the printed receipt with your phone. If it doesn't scan, increase the size and contrast, or use the text line instead of the image.
