Frisbii: sovereignty score and 8 European alternatives

Frisbii, formerly Billwerk+, is a subscription billing and payment platform for businesses in SaaS, media and retail and e-commerce. It handles recurring billing, a payment gateway, revenue insights and e-invoicing, and it offers an API, a Salesforce app and plugins for webshops and accounting tools. The platform is delivered as a cloud service and managed through a web dashboard.

Frisbii Germany GmbH is registered in Frankfurt am Main and operates the website together with Frisbii Media GmbH in Kempten. The company states that subscription and payment data is processed on European-based servers and claims compliance with GDPR, GoBD and PCI DSS. The website names no parent company or shareholders, so its ownership could not be confirmed. For a European organisation this means a German provider within the EU; contracts signed under the former Billwerk+ name should be checked against the new legal entity.

Why digital sovereignty matters with Frisbii

Frisbii is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Frisbii scores best on data residency.

Frisbii 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 Frisbii together with your other vendors and gives a total score, a heatmap and the main risk drivers.
