Common questions

Why does lapping eventually get discovered?+

The gap between recorded and actual receipts keeps growing as more accounts get shuffled, so the perpetrator must spend increasing time covering the trail. A vacation, illness, audit, or job change that interrupts the cover-up exposes the accumulated discrepancy.

How does an auditor detect lapping?+

By comparing the dates customer payments were received against the dates they were recorded and deposited, and by confirming account balances directly with customers, since the books will show a payment applied later than the customer actually made it.
