Business Address, Mail Service & Back Office

We have been simplifying administration since 2008.

Easily overcome bureaucratic hurdles: That is what our BK Wirtschaftstreuhand has been specializing in for over 15 years. Companies without own office not only receive a prestigious business address in prime Berlin location but also benefit from personalized administrative services – from mail handling to cloud-based archiving to back-office support. Over the years, we have consistently evolved – in terms of personnel, space, and digitalization. Find out more about the journey we have taken so far.

Our History in Years

This is how weh ave evolved

BK Geschichte


For the clients of our law firm in Berlin-Mitte, we establish BK Wirtschaftstreuhand. Our goal: to support asset-managing real estate companies that do not have their own office. We act as a link between property management companies, tax advisors, notaries, lawyers, and banks.


We are expanding our service to include back-office activities. For example, we support larger sales companies with order processing.


Continuously growing, our now ten-person team moves to larger offices near Berlin Tiergarten.


The new EU General Data Protection Regulation comes into effect. Therefore, we comprehensively develop our digitalized work processes.

BK Geschichte


Our focus changes. We now concentrate entirely on companies that primarily work digitally and remotely. Newly established startups are included, as well as small and medium-sized enterprises, investors, asset management companies, or companies with operational business.


We move to modern offices in Berlin's Charlottenburg-Wilmersdorf district.


We simplify mail management for our customers. Instead of forwarding emails, we now use an effective and data protection-compliant cloud solution. This allows postal documents to be read flexibly - regardless of time and place.


The present is nothing more than a successful milestone for us. We want to continue on our current path in order to enable our customers to run their business even more efficiently in the long term - and we would like you to do the same!
