From Broker to Broker

To ensure that onOffice software continues to offer the best possible conditions, a group of onOffice experts have been set up to create a close network between onOffice and our customers.

For this purpose, the groups meet once a year at our company headquarters in Aachen to discuss our various software packages and their technical development with our executives. The group consists of a maximum of ten experts.

As a member of the expert group, you, as a real estate broker, influence the future of onOffice by assessing existing issues, discussing planned projects and developing new ideas and suggestions. These innovative ideas have added great value to the users of the software. This is due to the fact that the expert's group was developed for you and your colleagues!

If our concept suits you and you want to become part of our expert group, please contact And Yes: We are also available for any sorts of enquiries!

"The expert group has helped me very much over the years, as OnOffice has openly explained to me how decision-making processes take place. In addition, an exchange with other colleagues in the working group is very constructive. OnOffice has created an instrument with the expert group to involve brokers even before further or new software development and to get the response directly from the users out of the market. I am proud to be part of this and will make a tangible, well-meaning contribution. "
