TaxMetall: sovereignty score and 8 European alternatives

TaxMetall is an ERP system from Vectotax Software GmbH in Mülheim-Kärlich for small and medium-sized manufacturing companies, including metalworking, mechanical engineering and plant construction. It brings order processing, production planning, shop-floor data collection, warehouse and materials management, purchasing, document management and financial accounting together on a single data foundation. According to the vendor, production planning can be done manually, automatically or with AI support. Editions range from start-up to larger companies, with CAD integration.

You can run TaxMetall on your own servers (on-premises) or use it as a cloud service. According to the vendor, the TaxMetall Cloud runs in a German data centre in Frankfurt am Main operated by a cloud partner. Vectotax is a family-run company headquartered in Germany, and no foreign parent company is stated. With on-premises use your data stays under your own control, and with the cloud edition it stays in Germany. The pages reviewed contain no public GDPR statement or data processing agreement for the product, so ask for the contractual terms.

Why digital sovereignty matters with TaxMetall

TaxMetall 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.

TaxMetall 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.

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