Get paid faster: clients scan the code in their banking app and the IBAN, amount and reference are filled in for them.
Add your IBAN in the Payment section of a euro invoice and the QR code appears next to your payment details. The amount is always the balance due, and the reference is filled in automatically from the invoice number when possible. No typing mistakes, no wrong references.
The QR code is created in your browser from your own data — nothing is sent to a payment provider, and there are no fees. It is a standard bank transfer.
There is no account and no server behind this invoice generator. Your business details, clients, products and invoices are stored in your browser's own database (IndexedDB) and never uploaded. The PDF is built on your device. That also means nobody else has a copy — download a backup from Settings → Backup now and then, and keep it with your accounting files.
QR codes work for invoices in euros with a valid IBAN and an amount due. The Payment section tells you what is missing.
The one you type, or an automatic one: for Slovenian businesses an SI00 reference built from the invoice number; otherwise the invoice number is put in the payment description.
