Sellsy: sovereignty score and 8 European alternatives

Sellsy is a French business platform that combines CRM, invoicing and payments in one product. It is built from modules for sales, invoicing, marketing and cash management, and it also offers e-invoicing as an approved platform, stock management, progress billing, an AI assistant and a mobile app. Sellsy targets sole traders, small and mid-sized companies, accounting firms and resellers, and is delivered as a cloud service.

Sellsy is part of the Italian TeamSystem group, so its ultimate parent is located in Italy, inside the EU. According to Sellsy, data is hosted in France with a French hosting provider that holds ISO 27001 certification. The product is proprietary and not open source. For a European organisation this means that both the vendor and the hosting fall under European jurisdiction. As with any group structure, it is still worth checking the data processing agreement and any intra-group data transfers.

Why digital sovereignty matters with Sellsy

Sellsy is headquartered in FR and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data. The ultimate owner is based in IT, also within Europe.

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

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