Crésus: sovereignty score and 8 European alternatives

Crésus is Swiss accounting, invoicing and payroll software for businesses, public bodies and associations. Its modules cover invoicing, payroll and financial accounting including VAT. The desktop program is installed on PC, Mac or Linux. A Crésus+ subscription adds extra services, and an optional cloud version, Crésus Cloud, provides an online desktop to access the software.

The publisher is Epsitec SA in Yverdon-les-Bains, Switzerland. The website does not state who owns the company, so no parent company has been established. Crésus Cloud runs on servers in Switzerland operated by its partner Silicom, which hosts the data and applications; the site describes encrypted connections and two-factor authentication. No GDPR statement or data processing agreement is published on the vendor's website. As a Swiss company, Epsitec sits outside the EU's legal framework. A European organisation considering the cloud version should check the processing terms and who can access the data.

Why digital sovereignty matters with Crésus

Crésus 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.

Crésus runs on infrastructure you choose and control yourself. You decide where the data lives, including fully within the EU if you want — this is not a fixed hosting choice made by the vendor.

Crésus is closed source, but you run the software yourself on your own infrastructure. The encryption keys and the runtime therefore stay under your own control, though you cannot audit or modify the source code. Ask about export options and open standards to limit software-level lock-in.

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