Audit Documentation under SA 230: Complete Professional Guide — Working Papers, Requirements, Retention & Professional Standards

Why Audit Documentation Is the Auditor’s Most Critical Defence

Audit documentation — the working papers — is simultaneously:

• Evidence that the audit was conducted in accordance with Standards on Auditing
• Support for the audit opinion expressed
• Defence against regulatory scrutiny, NFRA investigations, and ICAI quality reviews
• Knowledge base for the next year’s audit team
• Tool for engagement quality control reviewer

The maxim in audit practice is: “If it isn’t documented, it wasn’t done.”
