123erfasst: sovereignty score and 8 European alternatives

123erfasst is a set of mobile apps and accompanying software for construction and trades businesses. Its modules cover projects and site documentation (site diary, photos, forms), scheduling of staff, equipment and projects in a calendar, personnel data with time recording, absences and wage calculation under construction pay scales, equipment with maintenance and telematics, quality management and cost estimating. Staff record data on a mobile device; according to the vendor this also works without a network connection, and the data is synchronised later with the construction software in the office.

The provider is 123erfasst.de GmbH in Lohne, Germany, a company of NEVARIS Bausoftware GmbH, which states that it belongs to the Nemetschek Group. That group has its seat in Munich, so the owner sits in the same jurisdiction. The website does not say where the data on the 123 server is stored; ask about this, together with the data processing agreement, because the data concerns staff and working time. For a European organisation this is a German solution without a parent company outside the EU.

Why digital sovereignty matters with 123erfasst

123erfasst 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 123erfasst scores best on data residency.

123erfasst 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 123erfasst together with your other vendors and gives a total score, a heatmap and the main risk drivers.
