Auditing forms one of our firm's three core service areas, along with tax consultancy and business consultancy. Our auditors serve small and medium-sized enterprises (SMEs) from Essen, North Rhine-Westphalia and beyond. We provide the following range of services for all sectors of industry:

  • Individual financial statements: We audit the individual financial statements of corporations and partnerships in the form of both statutory and voluntary audits.
  • Consolidated financial statements: Group accounting constitutes a specific area in its own right. Auditing takes place in the context of full consolidation, proportional consolidation or equity valuation.
  • International accounting: Globally operative companies generally adapt their accounting to international standards (IFRS, US-GAAP).
  • Special audits: Our specialists also carry out auditing in connection with special events, such as the establishment, conversion, amalgamation or liquidation of companies.
  • Expert opinions: Our auditors draw up expert opinions in connection with reorganisation projects, insolvencies, settlements, fiscal or balance-sheet issues.
  • Company valuations: We value companies in accordance with recognised auditing methods for the purposes of sales or purchases.
  • Due Diligence: We oversee the careful examination of companies which is necessary in the course of sale or purchase transactions.

Interested? We look forward to hearing from you.
