My Motivation:

"My claim is to advise you exactly as dynamic as the e-commerce industry runs!"
(Christoph Kalmbach)

Hardly any industry has a shorter history and experiences greater change every year than the e-commerce industry. In an industry characterized by creativity and innovation, the bar for success is particularly high. If you want more than just to keep up with the competition, you have to know everything there is to know about the latest trends and technologies, develop new distribution models, and satisfy the needs of customers who are as demanding as they are informed.

In short, once one task has been mastered, the next challenge awaits.

We know the typical challenges you face in the e-commerce industry. We accompany you in development and marketing processes of new formats, we know the accounting pieces (e.g. timing of revenue recognition), the (sales) tax sticking points (e.g. dropshipping, distance selling etc.) as well as the corresponding technical interfaces (e.g. electronic payment systems).
