Planning an Audit of Cost Statements

Planning an audit of cost statements and records is considered necessary to ensure achievement of audit objectives with available resources and securing coordination with the auditee.

Before planning, the Cost Auditor is to ensure that his appointment as auditor is proper. Legal formalities, ethical requirements, understanding of ToR including the units, products / services to be covered and scope of coverage have been properly understood by him.
The nature and extent of planning activities will vary according to size and complexity of entity’s activities, number of products covered, processes and operations involved.

Planning also helps the cost auditor in the risk assessment procedures.  However, planning the nature, timing and extent of specific further audit procedures depend on the outcome of those risk assessment procedures.
