Audit Purchases to Check Revenue

BY GARY M. BARNBAUM

I just took your test, “What Is Your Fraud IQ?,” (Dec. 07, page 56). I received a score of 90%.
 
However, I do want to take issue with the wording in one of the questions. In 10(a), you described “Cost of Goods Sold” as an account. Technically, that’s not ­accurate. Cost of goods sold is a subtotal made up of a number of accounts, including the account “purchases.” (Although, oftentimes, cost of goods sold is reflected as one number on a published condensed financial statement.)
 
Therefore, one way to validate fictitious revenues (and also unrecorded revenues) is to audit purchases. This type of so-called “backward auditing” is not only commonly used for the purpose of validating sales, it is commonly used by government agencies for the same purpose, especially with sales tax audits.
