List of audit procedures in external audit

Audit procedures in external audit play important role. Without performing these procedures, an auditor may not verify audit assertions and issue audit report.

It’s advisable to plan audit procedures in line with audit assertions. For instance, for a sales audit, the auditor needs to verify assertions like completeness, accuracy, cut-off, classification, occurrence etc.

Similarly, for account balance, different audit assertions are applicable. These assertions include completeness, existence, valuation, rights and obligation.

It’s important to note that one audit procedure can address multiple assertions. However, all of the assertions must be verified by the auditor. This enables them to conclude the conduction of a reasonable audit.

Let’s discuss different audit procedures and how these help collect audit evidence.
