Swiss QR Bill for .NET

Open-source .NET library to generate Swiss QR bills. Try it yourself and create a QR bill.

Introduction

The Swiss QR bill is the QR code based payment format that started on 30 June, 2020. The payment slip is sent electronically or presented online in most cases. It can still be printed at the bottom of an invoice or added to the invoice on a separate sheet. The payer scans the QR code with his/her mobile banking app to initiate the payment and then just needs to confirm it.

If the invoicing party adds structured bill information (VAT rates, payment conditions etc.) to the QR bill, the payer can automate the booking in accounts payable. The invoicing party can also automate the accounts receivable processing as the payment includes all relevant data including a reference number. The Swiss QR bill is convenient for the payer and payee.
