What is an auditing engagement?

Auditing engagement is when an auditor or auditing firm engages with a business to conduct an independent audit of its financial statements with an intention to express an audit opinion.

It aims to provide an opinion on the fairness and accuracy of the financial information presented by an organisation. During such a process, the auditor assesses internal controls, verifies business transactions and account balances, preparation of financial statements in line with applicable laws and checks the overall financial health.

Furthermore, the audit findings are documented in a report outlining any material misstatements and recommendations for improvement.

You or the auditor can submit the report to shareholders, investors, or regulatory bodies. However, ensure the entire process follows professional auditing standards and regulatory requirements. It ensures transparency and integrity of financial reporting.
