The math most CFOs don't know

Most mid-market CFOs underestimate their company's expense fraud losses by 60–80%. ACFE's 2024 Report to the Nations finds that 13% of all occupational fraud cases involve expense reimbursement fraud, with a median loss of $40,000 per case and a median duration of 18–24 months before detection.

For a typical mid-market company with $1.5M in annual expense spend, this translates to $20,000–$45,000 in annual losses that go uncaptured because most finance teams don't have the time or tooling to forensically review every receipt.

A preview — 2 of the 5 fraud types

The full guide details all five fraud types with anonymized case examples and detection methods. Here are the first two.

01 · Duplicate receipts ~25% of cases

What it looks like: The same receipt submitted in different reports, often weeks or months apart. With smartphone photography, the same receipt can be photographed at slightly different angles to look like different submissions.

Anonymized example

A sales executive submits the same $250 client dinner receipt twice — once in March, once in May, for two different supposed client meetings. The second submission goes unnoticed for 8 months until a year-end audit reconciliation finds the duplicate.

02 · Inflated amounts ~20% of cases

What it looks like: A legitimate receipt with digitally edited values. Photo editing tools make this trivial — change one digit in an image, no one's the wiser.

Anonymized example

An employee submits a legitimate $80 hotel receipt that's been digitally edited to show $180. The fraud accumulates over 18 months across $40,000+ in inflated travel expenses before discovery during a quarterly audit.

How detection methods compare

Different detection approaches catch different fraud types at different rates. Manual review catches ~10%. Modern expense software ~30–40%. AI-powered fraud detection ~90–95%. The full guide breaks down each method with specific strengths, weaknesses, and operational fit.
