Our history
Every story has its beginning. The story of concellens begins in September 2011. With over 25 years of combined experience from countless SAP projects, Frank Scheller and Jens-Uwe Klempien decide to set up their own business. Their clear vision – to offer specialized consulting at the highest level through partnership-based cooperation with customers and partners and sound technical expertise.
Today, concellens is a competent consulting firm in the field of group consolidation and a partner of SAP. We support large corporations and medium-sized companies with their accounting and make the consolidation process easier for them. With the help of the latest consolidation solutions from SAP as well as our own developed rules and templates, we guide our customers to corporate success and help them save time and resources. Over the years, we have remained true to our vision of working together as partners. The success of our daily activities is determined by three key factors: a competent team of experts, reliable partners and our valuable customers.
