Billingo: sovereignty score and 8 European alternatives

Billingo is an online invoicing and electronic receipt service from Hungary, aimed at freelancers, micro-enterprises and small businesses. Users issue invoices and receipts, and electronic receipts are reported automatically to the Hungarian tax authority NAV. The service also offers bank synchronisation, a card terminal product, access for accountants and an API, and it is available as a web application and mobile apps for iOS and Android.

Billingo Technologies Zrt. is registered in Budapest, so the provider is established within the EU. The imprint names Amazon Web Services EMEA SARL in Luxembourg as hosting provider, but it does not state the AWS region or where customer data is stored. The public sources consulted did not reveal the company's owners, so the ownership structure remains open. The service is not open source. A European organisation should confirm the data location and processing terms, since the tax-authority integration is specific to Hungary.

Why digital sovereignty matters with Billingo

Billingo is headquartered in HU 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 Billingo scores best on data residency.

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