Certified Internal Auditor (CIA) Part 2: Practice of Internal Auditing — Question 198

An internal auditor wants to assess the completeness of sales invoices issued by the organization over a period of time. Providing that all the necessary data and analytics software is accessible, which of the following types of analysis would be appropriate to satisfy the auditor's objective?

Answer options

Correct answer: D

Explanation

Gap analysis is the most suitable method for identifying missing invoices, as it compares expected sales data with actual issued invoices. Payment terms, duplicates, and aging analyses focus on different aspects of invoicing and do not directly address the completeness of the issued invoices.
