Focused on our Clients

We develop together with our clients. For more than 50 years – if you include the predecessor company of Acconsis – we have acquired valuable market experience. The type and scope of our expertise is very much shaped by our customers.


ACCONSIS für mittelständische Unternehmen



Medium-sized businesses

In global comparison, medium-sized businesses in Germany convince with their excellent product expertise, outstanding customer focus and powerful corporate culture. We provide tax and legal consultancy services to these businesses and, as chartered accountants, strengthen their position in dealings with authorities and investors. We also enhance their management skills, e.g., in the area of corporate finance. 

Globally operating companies

We assist globally operating companies with their cross-border operations. Foreign corporations who want to set up new subsidiaries in Germany and manage these with the utmost efficiency rely on our expertise and our outsourcing services. Domestic clients who turn to exporting to further their expansion are supported by our partner networks in their target markets, e.g., in the Far East or North and South America. We also offer reliable international tax consultancy services. As chartered accountants, we provide additional security for merger & acquisition strategies, e.g., for the acquisition and sale of companies or shareholdings in foreign countries.

ACCONSIS für Privatpersonen



Private individuals

Ongoing tax consultancy is one of the most popular services we offer for private individuals, followed by legal advice. We offer family governance and family office services to families managing large estates. 


Quality over quantity: freelancers operate with a comparatively small number of staff. Next to expertise and knowledge, efficiency is a decisive criterion for the success of freelancers. We help you minimise risks, avoid unnecessary costs and optimally exploit productive resources.

Hotel and catering industry

Great personal commitment, often from the whole family, makes hoteliers and restaurant owners remarkably successful. With our comprehensive services, including tax consultancy, legal consultancy and business consultancy, we can protect them from unexpected liabilities and pitfalls and help them to sustainably increase their profitability.

Public institutions and local authorities

Structures and processes used by municipal institutions increasingly approximate those used in industry. We support local authorities and public institutions who often face significant challenges, e.g., in the area of financial management.
