bps² Treuhand GmbH Wirtschaftsprüfungsgesellschaft

Founded in April 2020, our independent public audit firm is able to carry out audits and other services reserved to German public auditors. We follow the practice approached for many years at Dr. Fette & Partner Partnerschaftsgesellschaft mbB serving as coordinators and client care specialists our clients can rely on, also in the area of auditing.

Dr. Fette & Partner Partnerschaftsgesellschaft mbB

Dr. Fette & Partner Partnerschaftsgesellschaft mbB is an interdisciplinary professional partnership that arose from the law firms of Dr. Fette in Krefeld and Bernhard Ernst in Duisburg, both with a tradition extending back more than thirty years. We advise our clients in legal, tax and economic matters with a strong team of qualified employees and professionals who work as lawyers, tax advisors and auditors in Duisburg and Krefeld.

We believe in client care writ large. Meaning our clients are in expert hands. We strive for excellence in everything we do. At bps² we perceive ourselves to be partners, on an equal footing with our clientele — transparent, proactive, providing for solution-oriented services. But not only. We are a team of innovative professionals, well aware that one size doesn’t fit all. That each situation requires an individual, personalized approach. We are open and responsive, providing assistance and recommendations with an individual touch.

Enterprising means acting: Our job is to help you remove obstacles and hurdles that detract you from your day-to-day business. We take care of your tax, financial and business management needs, and rely fully on digital transformation technologies where appropriate. So you can devote yourself to what you do best, while saving time and money.


At bps² you don’t just work with tax advisors. Or lawyers. Or business management experts. You work with an integrated team of more than 30 experts. All under one roof. Always as partners on an equal footing. At bps² we are able to provide up to date expertise combined with decades of experience of the firm founders. This collective know-how is augmented by the lived digital transformation of our young team members. Always responsive and responsible in the interest of our clients.

Our firm started out with Dr. Hans-Peter Fette as client liaison — with his clear focus on profitability and exacting standards — and Bernhard Ernst, a certified tax advisor and tax planning expert. The following individuals are now leading the firm into the future:

  • Thomas Bittdorf with his eye for detail; precision analyses; process, digital transformation and corporate expertise; healthcare expertise; banking background; and trained public auditor;
  • Maria Wangerin with her holistic tax expertise ranging from partnerships and corporations to group structures;
  • Thomas Pickert, a consultant with his own corporate experience, business background and understanding of precision processes.

They are assisted by Gerrit Held, and the entire team of tax technicians and Bilanzbuchhalter (IHK-examined accountants).

Not to mention that we bring all the necessary expertise and skills to the table and are cutting-edge when it comes to digital transformation and modern communication technologies.

The entrepreneurial perspective is in our DNA. We speak your language.

Advisory, tax and audit — the trifecta of disciplines mastered at bps². We pursue a holistic approach to advise you: Our professional partnership ensures an expedient balance between business strategy, legal structuring and tax planning. You can reliably establish and structure your company with our support — we conscientiously navigate you through the legal and regulatory hurdles.

With our audit firm bps² Treuhand GmbH Wirtschaftsprüfungsgesellschaft, we can issue the required attestations for the statutory or voluntary audit of your financial statements and assume other duties reserved to public auditors.
