QR Modul: sovereignty score and 8 European alternatives

QR Modul is a web-based service for creating Swiss QR-bills, operated by Schwarzenbach KMU Services AG of Zurich, Switzerland. It is aimed at small businesses, sole traders, associations, donation organisations and online shops that do not want to install ERP software. Besides single QR payment slips and complete invoices, it offers a series function, dispatch by post or email, a debtor manager, an invoice-template manager and several payment slips per invoice. Connections exist for bexio, WordPress shops and Zoho. Invoices are stored in the vendor's cloud.

Schwarzenbach KMU Services AG is headquartered in Switzerland, and its imprint names no parent company. The website does not state where the invoice data is hosted, so ask the vendor. Switzerland is not an EU member but is an EFTA country with an EU adequacy decision for data protection. The privacy terms refer to the GDPR as a legal basis and disclose website use of Google Analytics, reCAPTCHA and web fonts, with possible transfers to the US. Those items concern the website; check separately which subprocessors handle invoice data.

Why digital sovereignty matters with QR Modul

QR Modul is headquartered in Switzerland and falls under Swiss law, including the revised Swiss data protection act. Switzerland is not an EU member, but the European Commission recognises its level of data protection as adequate. Its Swiss headquarters does not by itself bring it under US legislation such as the CLOUD Act.

QR Modul hosts data in Switzerland only. Switzerland is not part of the EU or the EEA, so the GDPR does not apply there directly; the European Commission does recognise Swiss data protection as adequate, so personal data can go there without extra safeguards. Our model therefore scores it between EU hosting and hosting outside Europe. If you require strictly EU hosting, take this into account.

QR Modul is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs QR Modul together with your other vendors and gives a total score, a heatmap and the main risk drivers.
