Our philosophy

Our approach to special and mandatory audits is based on a holistic understanding of the regulatory framework and industry-specific requirements. We combine in-depth expertise with a practical view of the individual circumstances of each mandate. Our focus is on designing audit processes in such a way that they not only meet legal obligations but also create real added value – through efficiency, traceability, and clear recommendations for action.

From preparation and execution to communication with supervisory authorities, we attach great importance to transparency and collaborative exchange. We don’t just audit, we explain, evaluate, and provide orientation. Our experts combine legal, business, and technical expertise to make complex audit objects understandable and identify risks at an early stage. In this way, we ensure quality, trust, and sustainable compliance in every step of the audit process.

Special Audits in the Public Sector

Special audits in the public sector serve to specifically analyze specific issues outside of the regular annual audit. The subject matter may include the use of subsidies, economic efficiency, award procedures, or the regularity of management in accordance with § 53 HGrG. The goals are transparency and safeguarding the use of public funds. The independent view of the auditing profession enables risks to be identified at an early stage, processes to be optimized, and the basis of trust vis-à-vis politics, administration, and the public to be strengthened.

Our focus areas

  • Audits according to § 53 HGrG (for companies in public ownership)
  • IDW PH 9.400.3: Audits in connection with subsidies / funding programs and proof of use audits
  • Price audits public contracts
