Skimming

Definition

An off-book cash theft: revenue is stolen before it enters the accounting system, so no entry is ever made. Skimming is harder to detect because there is no accounting discrepancy to find; detection usually relies on physical controls, surveillance, or tip-offs rather than records review.

Common questions

What makes skimming hard to catch in accounting?+

Skimming removes cash before it ever enters the books, so there's no accounting mismatch to trigger controls. Traditional account-matching systems can't detect what was never recorded. Detection depends on external evidence like customer receipts or till recordings showing a transaction that the company records never capture.

How is skimming different from other cash theft?+

Skimming intercepts cash before accounting entry, while other cash thefts might steal from a recorded account (creating a discrepancy). Because the skimmed revenue never reaches the records, it leaves no direct accounting gap. The thief's skill is staying invisible to the ledger.

What evidence actually catches a skimmer?+

Customer receipts, till surveillance footage, and revenue pattern analysis. If a till shows more transactions or payments than the company's records, or if customer receipts don't match recorded sales, the scheme unravels. External data sources that the thief didn't control become the proof.
