The best-practice steps included in this audit program can be used by organizations to perform a purchasing rebates audit.

Sample work steps include observing and documenting a workflow and/or narrative to document the understanding of the purchasing rebates process, documenting the methodology behind the inventory adjustments and assumptions used when recording the inventory adjustments/entries, tracing and agreeing upon purchasing data used in the rebate calculations to the purchasing/supplier source data, and verifying that supporting documentation exists for each cash and credit rebate applied by accounts payable.
