Auditing

Our business:
Auditing is one of our core competencies and a key pillar of our range of services

Auditing is and always will be a major part of our business. Accordingly, our focus in this area cuts across many different levels. This is reflected among other things in the large number of Wirtschaftsprüfer (German public auditors) on our staff who benefit from ongoing professional development in our in-house WiTreu Academy, and of course in our investment in quality assurance and digitalisation.

Our goal:
Trust and certainty

Our primary focus in our range of auditing services is on one goal: Providing you and your business partners with maximum certainty, by means of trustworthy and reliable business information based on our longstanding experience and the high quality of our work. On the basis of our audit reports and findings, we support medium-sized enterprises and business owners in complex decision-making situations. Because when it comes to assessing opportunities and risks and to taking well-founded business decisions, reliable figures are absolutely essential.

Our mission:
Added value for you and your business

We see our auditing services as being about far more than just compliance with regulatory requirements – every time, we also seek to generate added value for you and your business. This includes keeping a watch on potential ramifications for shareholders. We equally maintain a focus on tax implications: All Wirtschaftsprüfer on our staff are also qualified Steuerberater (tax advisors). Where your assignment requires, we additionally coordinate staff for you from our other competencies.

Our core competencies

Auditing

We audit annual, consolidated and interim financial statements in accordance with German GAAP and IFRS. With our internationally oriented expert team of auditors, tax advisors, IT consultants and lawyers and through our membership of AGN International, we can also support you in complex international group audits and in the auditing of foreign subsidiaries.

ADDITIONAL FOCUSES

Special audits

In various situations, you may need to have certain matters verified and confirmed by an external expert – whether it is to comply with statutory or contractual requirements or on a voluntary basis to support or secure your own negotiating or decision-making situation. As experienced auditors, special audits of this kind are part of our core business. In close collaboration with our tax advisors, lawyers and IT consultants, our focus here is primarily – but not exclusively – on the following services:

 

  • Auditing services on company formation, changes of legal form and changes in share capital (including impairment testing)

Tests of IT control

IT systems are becoming increasingly complex and are involved in almost every operational business process. Constantly growing demands are placed on their performance and reliability. We therefore carry out targeted IT system audits and mass data analyses as part of our financial statement audits and in the course of separate engagements. A special focus is placed on auditing interfaces and IT controls. These audits are carried out in close consultation between our IT-proficient auditors and our IT experts.

Overview of our services:

  • IT system audits in accordance with IDW PS 330/IDW FAIT 1 (both in connection with the audit of the financial statements and as a separate audit)
  • IT security audits (IT security policies, data security, authorisation policies, etc.)
  • Conduct of mass data analyses (both in connection with the audit of the financial statements and as a separate audit)
  • Data protection audits
  • Data and interface testing to simulate digital tax audits with the tool used by the taxation authorities
  • IDW PS 880 on the auditing of software products at the manufacturer and the issuing of software certificates
  • Auditing of compliance with German proper accounting principles (GoB) in the case of electronic archiving

Audit-related consulting services

The professional designation “Wirtschaftsprüfer” – German Public Auditor – is widely recognised as a hallmark of authoritative professional expertise, and it naturally makes sense to apply that same expertise in areas beyond the traditional audit portfolio.
