Who We Are

Software Publisher + Consulting Partner

SK Consulting is a Luxembourg-based Microsoft partner with a dual identity: we build software products for Business Central (8 apps on Microsoft AppSource) and deliver consulting services (ERP implementation, migration, AI transformation).

Founded with deep roots in Luxembourg's financial and business ecosystem, we understand the unique regulatory, linguistic, and operational requirements of organizations in the region — and we've built products specifically to address them.

Over 10+ years, we've grown from a local consulting firm to an international software publisher with customers across Luxembourg, Belgium, Netherlands, Germany, Austria, Malta, and beyond.
