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.

Getting started

1. Create a new Visual Studio project for .NET Core 3.x (File > New > Project... / Visual C# > .NET Core > Console App (.NET Core))

2. Add the library via NuGet:

   Either via Project > Manage NuGet Packages... / Browse / search for qrbill / Install

   Or by running a command in the Package Manager Console

Install-Package Codecrete.SwissQRBill.Generator -Version 3.4.0

3. Add the code:

using Codecrete.SwissQRBill.Generator;
using System;
using System.IO;

namespace Codecrete.SwissQRBill.Examples.Basic
{
 class Program
 {
 static void Main(string[] args)
 {
 // Setup bill data
 Bill bill = new Bill
 {
 // creditor data
 Account = "CH4431999123000889012",
 Creditor = new Address
 {
 Name = "Robert Schneider AG",
 Street = "Rue du Lac",
 HouseNo = "1268/2/22",
 PostalCode = "2501",
 Town = "Biel",
 CountryCode = "CH"
 },

 // payment data
 Amount = 199.95m,
 Currency = "CHF",
 
 // debtor data
 Debtor = new Address

 // more payment data
 Reference = "210000000003139471430009017",
 UnstructuredMessage = "Abonnement für 2020",

 // output format
 Format = new BillFormat
 {
 Language = Language.DE,
 GraphicsFormat = GraphicsFormat.SVG,
 OutputSize = OutputSize.QrBillOnly
 }
 };

 // Generate QR bill
 byte[] svg = QRBill.Generate(bill);

 // Save generated SVG file
 const string path = "qrbill.svg";
 File.WriteAllBytes(path, svg);
 Console.WriteLine($"QR bill saved at { Path.GetFullPath(path) }");
 }
 }
