Swiss QR Bill for WooCommerce is a specialized plugin designed to facilitate QR bill payments for online shops operating in Switzerland and Liechtenstein. Launched in conjunction with the ISOstandard, this plugin allows shop owners to utilize either a QR-IBAN or a standard IBAN for generating valid Swiss QR bills, effectively replacing the older ESR payment slips. It is essential for users to have a functioning WooCommerce installation and the PHP 'intl' extension enabled on their web hosting, ensuring compatibility and optimal performance.

The plugin includes a variety of features such as automatic PDF generation for invoices, which are emailed to customers upon order completion. Shop owners can customize invoice data, including their logo and address details. Additionally, restrictions can be imposed based on customer registration status and product categories, enhancing control over payment options. With support for CHF and EUR currencies, the Swiss QR Bill plugin is a comprehensive solution for Swiss merchants looking to modernize their payment processes.
