Internal control systems

The internal control system (ICS) of a corporation manages and monitors its accounting-relevant processes. The accuracy and correctness of the annual financial statements is largely ensured by the reliability of the ICS installed in the corporation. The auditor investigates the ICS implemented in the corporation and establishes its suitability and effectiveness. Due to the intensive use of IT to implement the ICS, the system check is partly designed as an IT system check. The system check covers outsourcing accounting-relevant processes and even includes the ICS of external service providers. The system check begins even before the balance sheet date.
