You require continuity. We serve our clients for generations

WirtschaftsTreuhand is a byword for trust and constancy.
The roots of the WirtschaftsTreuhand Group go back as far as 1939.

Fully independent, we are reliable and trusted partners, largely to mid-caps, providing auditing, tax, legal and consulting services for more than seven decades. Today we are a constant and established force with some 140 staff and five locations, providing end-to-end support for businesses, the public and the non-profit sectors, shareholders and private individuals.

This trust-based and long-term partnership from the outset creates new opportunities to work together on shaping the future. And that in turn is reflected in the high standards we share with all clients. WirtschaftsTreuhand: Rethinking business.

At WirtschaftsTreuhand, executive service is standard for every client. From the outset, one of our partners is there for you as your individual point of contact in all matters, and will stay with you for many years. You are thus assured expert, one-stop advice by a dedicated professional who is an entrepreneur like you. In the background, your WirtschaftsTreuhand partner coordinates a seasoned, expert team covering all disciplines and is actively involved in all issues at all times.

On key issues, we assign two professionals from each discipline. This ensures that you have constant support. Our personal consulting approach and flat hierarchies mean that you benefit in terms of short and very direct lines of communication, a clear sequence of events, fast processes and high-quality outcomes.
