Our History

The business adviser and accountant firm DYN SA was created following the merger of the fiduciaries HB Partners, a specialist in advice for SMEs, and Tax-Praxis, a specialist in tax advice.

Established at the heart of Lausanne on avenue de la Gare, DYN SA is a young, dynamic, multilingual firm. Its employees speak French, English, German, Spanish, Italian and Russian fluently.

Dynamics is a science of the motion of bodies under the action of forces.

Thus, the name DYN marks our dynamism and determination to provide high quality work and assist our customers on a daily basis in establishing and monitoring their businesses, ensuring the latter’s good economic development and assisting in transactions and administrative tasks that are increasingly complex.

Dyn’s activities encompass all of Switzerland and its network allows it to meet the expectations of international customers.

DYN may also assist its customer in all business matters through its partners active in legal, banking, insurance and real estate fields in Switzerland and abroad.

Our Vision

Accounting is a management tool that is of paramount importance in business management, whether for drawing up a budget, determining income or providing an accurate picture of the firm. It is also used for tax analysis and optimised tax savings.

Thus, reduced costs and decreased risks are achieved by efficient administrative management. This is why our team is composed only of specialists in their field. We place particular emphasis on regular further training, since it is our expertise that allows us to assist our customers in creating the value for their businesses.

DYN – the measurement of your success

Efficiency is also measured by our acts and the traces we leave. It is for this reason that DYN pays close attention to its carbon footprint. We favour recycling and electronic filing in order to reduce paper consumption. We use dynamic, innovative systems in all our work processes.

We use new IT, accounting and financial technologies so that our customers benefit from the latest innovations and the most efficient tools. We place great importance on data security, which is why all data is hosted in Switzerland.

Our social responsibility leads us to train apprentices and support non-profit organisations.
