Mercateo (Unite Procurement): sovereignty score and 8 European alternatives

Mercateo, now operating under the Unite brand as Unite Procurement, is a German B2B e-procurement platform. Founded in 2000, it connects buyers and suppliers. Its online shop sells goods such as office supplies, IT hardware, tools and workplace safety items, exclusively to companies, tradespeople and freelancers. A procurement portal helps buyers organise purchasing, and suppliers and manufacturers can list and promote their products. Since the 2021 rebrand the Unite network combines the Spotmarket, the Procurement Portal and Financial Services. The platform is delivered as a web service.

Mercateo started in Munich and moved its group headquarters to Leipzig in 2019, so it is a German company within the EU. Its public pages do not state where the platform is hosted or which sub-processors are used, so a European buyer should ask for the hosting region in the contract. The platform is proprietary and not open source.
