Codecrete.SwissQRBill.Generator 3.0.0

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 new QR code based payment format that started on 30 June, 2020. The old payment slip will no longer be accepted after 30 September 2022.

The new payment slip will be sent electronically in most cases. But 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. The payment just needs to be confirmed.

If the invoicing party adds structured bill information (VAT rates, payment conditions etc.) to the QR bill, the payer can automate 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.

More examples can be found in the Wiki
