Scan-to-Pay QR Code
Last updated: 2026-05-28
Every Duefy payment page (/pay/{slug}/) shows a QR code that, when scanned
with a phone camera, opens the same payment page.
When is this useful
- Print the invoice + hand it to your client. The QR lets them pay from their phone without typing a URL or hunting through email.
- Forward to accounts payable. If your client forwards the email or the PDF to a bookkeeper, the bookkeeper can scan and pay directly.
- Email signature / business card. Add the printed page to a presentation or sales packet — scanning is friction-free.
Where it shows up
- The bottom of the payment page (web view)
- The printed version (Cmd+P / Ctrl+P) is clean — extra UI is hidden, the QR + invoice details remain, and the QR is sized for clean scanning
How it works
The QR encodes the same URL as the pay page slug. It's stable — printing or sharing it is safe even if you reissue the invoice (the slug doesn't change when amount or due date is updated).
