Gyseler AG has been granted national approval by the Federal Audit Oversight Authority (RAB) and is officially authorised to carry out limited and regular audits. We are registered as an Auditor on the overview of the Federal Audit Oversight Authority as follows:
Register of audit providers
Many SMEs would not want to dispense with an audit, even if their legal obligation to do so has been eased. Reasons for this may be ensuring that the annual financial statement is checked by specialists or preventing a worse rating with the lending bank.

As an auditing firm, in addition to limited and regular examination of the annual financial statement, we also conduct special examinations (formation reports, agreements on contributions in kind, capital increases/reductions, subordination agreement).
We offer cooperation with fiduciary companies that have not received a permit from the Federal Audit Oversight Authority.
We are also registered as an auditor for compliance with the law on money laundering (GWG) by the self-regulatory body of Treuhand Suisse.
