Skimming (Employee Cash)

As old as cash handling itself; the ACFE has measured it as a distinct occupational-fraud sub-type in every Report to the Nations since 1996.

Skimming, taking cash before it is recorded, is the oldest form of occupational fraud and the reason cash registers were invented in 1879. The ACFE's Report to the Nations has tracked it since 1996 as a sub-type of asset misappropriation, most common in small businesses, restaurants, bars, churches and cash-heavy retail. Casinos gave it a famous form (the Las Vegas 'skim' of the 1960s-70s). It persists wherever cash is handled with weak reconciliation.

An employee pockets cash from a sale and never rings it up, voids the transaction after the customer leaves, under-records receipts, or intercepts customer payments on accounts receivable and covers the gap by 'lapping' later payments. Owner-managers skim to evade tax. Because the money never enters the books, there is no accounting entry to find; it shows up only as unexplained margin shrinkage, inventory gaps or complaints from customers whose payments went missing.

Needs nothing but access to a till or the mail and the nerve to take small amounts repeatedly; because the cash never enters the books it is 'off-book' and the hardest fraud to detect by audit. ACFE finds most cases are caught by tips, not controls, and most employers quietly dismiss rather than prosecute, so criminal cases are the exception.

No body publishes a skimming-only total; the ACFE estimates organisations lose about 5% of revenue to all occupational fraud, with a $120,000 median per asset-misappropriation case (ACFE 2024). The largest recent prosecuted cash case is about $1 million (Braasch, 2025). Small businesses can be pushed into insolvency by a single trusted employee.
