For over 40 years, Zöller & Dicke has been a renowned tax consulting firm in Dortmund, Germany, known for its use of cutting-edge technology to improve its internal workflows and client services.


To date: a time-consuming and error-prone process with a sea of physical documents

In the hectic daily routine of tax consulting, countless documents and contracts have to be managed, organized and processed.

Before implementing tegolySIGN, Zöller & Dicke faced the challenge of signing documents manually. This resulted in inefficient workflows, high costs, and an overall slowdown in processes.

Mr. Zöller, described the situation as follows: “The process was extremely problematic for our team, as we had to print, send and re-scan documents that needed to be signed by the client. This analog process is slow and error-prone. It quickly became clear that we needed a more efficient, digital solution to this problem. It should reduce the workload and so that we can provide a consistent quality of service to our clients. It was also very important to us that the future solution be easy to use for both our employees and our customers.”
