Honored by clients:
Germany's best auditors

For the third time, we have been recognized by Manager Magazin: We are again among Germany's best auditors in the "Mittelstand" category in 2022/2023.
There is no way to apply for this competition. Through a survey of over 1,000 managers from German SMEs, an exclusive group of auditors was filtered out to qualify for the final round. Only these auditors were allowed to take part in the final study. Mauer Group was invited to undergo a detailed evaluation, which consisted of a survey of internal key figures and a survey of reference customers.
We successfully passed the assessment of the reference clients in the specialist areas of audit, advisory, corporate finance and digital transformation and are among Germany's best auditors in 2022/20233.
We are particularly pleased about the confirmation that we speak the language of SMEs and understand how to deal with the special challenges of SMEs and entrepreneurs. In which areas can we support you? Please feel free to contact us.
