To ensure adequate financial controls during an audit, a company should focus on three main areas: preventing fraud and errors, detecting irregularities, and correcting deficiencies. A strong segregation of duties and a system of authorization should be implemented to avoid fraud and mistakes. This helps to ensure that no single individual can control all aspects of a transaction and limits the opportunity for fraud or errors. Detecting irregularities involves implementing monitoring and review procedures to assess the effectiveness of the company's financial controls regularly. This may include establishing an audit committee that meets periodically to review financial processes, reports, and results. Correcting deficiencies involves taking appropriate action to address any identified shortcomings or weaknesses in the financial control system. This could include revising policies and procedures, providing additional employee training, or implementing new technology to enhance the company's financial control systems.
