Make sure to highlight any and all discrepancies you feel are material and warrant further investigation (if there are any such discrepancies, discuss in detail how you would investigate material discrepancies appropriately). Regardless of the existence of discrepancies, identify and describe two additional substantive tests of detail to perform over sales revenue. Use MS Excel to complete your analyses. In all cases, make sure you clearly show how you developed your expectations. Also, make sure you clearly and adequately document your investigation.
