Auditors and expert opinions in the Basel area

So that you can count on your figures

We see statutory audits not as a compulsory exercise, but as an opportunity for your company. Our clients benefit from the many years of experience of our audit experts in all sectors, legal forms and audit cases.

Revision

Our auditing experts know your business and personally oversee the audit from A-Z. That's why we don't produce any empty runs, but provide valuable recommendations for optimizing your accounting and the underlying processes in addition to the required confirmation of your financial statements. rta is licensed as an auditing company / auditing expert by the Federal Audit Oversight Authority FAOA and, as a member of EXPERTsuisse, is always up to date with the latest auditing practice.

Special tests

Audit confirmations by independent auditors are increasingly required by law. Our licensed auditing experts handle projects such as audits of company formation, capital increases or reductions, audits in accordance with the Merger Act, etc. in a customized manner.

Expert reports and appraisals

We are neutral and independent experts for all accounting, finance, tax and legal issues.
