Purchasing Fraud: Auditing and Detection Techniques

Course Description

Print-friendly Course Description and Outline

The purchasing process is one of the riskiest areas when it comes to fraud and abuse. The many opportunities associated with the process can leave companies vulnerable to both internal as well as external fraud. In fact, some procurement fraud schemes are the hardest types of fraud to detect (e.g., kickbacks and other off-book schemes).

This interactive course, which is a joint effort between The IIA and Deloitte & Touche,  will help you to assess an organization’s risks relating to purchasing fraud, identify controls that can mitigate those risks, design audit tests to detect purchasing fraud, and investigate evidence of fraud occurring. Case studies will be used to show you how to apply the recommended techniques to common purchasing fraud situations.
