Join us on our journey
Copartner Revision AG was founded in November 1992 and has provided services in auditing, fiduciary services & taxation, and management consulting from the outset. It began with a small and qualified team that primarily supported and provided comprehensive services to small and medium-sized enterprises in northwestern Switzerland.
Over the years, Copartner has grown steadily and now operates across the entire German-speaking part of Switzerland. Today, we are an established and respected advisory firm serving clients across German-speaking Switzerland in the areas of auditing, accounting and tax services, as well as management consulting.
Excellent consulting and consistent customer focus have shaped Copartner's self-image since the company's establishment. We build on long-term, stable partnerships and create sustainable value through trust and reliability.
Based on the number of audit engagements registered in the commercial register, we are ranked second in the canton of Basel-Stadt and fourth in the canton of Basel-Landschaft. Nationwide, we are ranked 12th and are the third-largest audit firm in Switzerland to hold accreditation as an audit expert with the Audit Oversight Authority (RAB).
We combine professional standards with the corporate culture characterised by team spirit, openness, and mutual respect. We are proud of our independence, which is why Copartner is entirely owned by its senior management.
