Expense Fraud

Expense fraud can happen when an employee claims money for a cost the business does not owe, such as a receipt that is fabricated, altered, submitted twice or used for personal spending. Under ordinary usage it requires intent, since a missing receipt or wrong cost code may be a mistake instead, and that distinction should be kept in mind when reviewing a claim.

The Association of Certified Fraud Examiners (ACFE) includes expense reimbursement in its occupational-fraud classification, and its examples and a practitioner guide on reimbursement controls show how false or inflated claims can arise, but these sources identify risk patterns, not proof that a particular employee acted dishonestly. A company needs a clear expense policy stating what business purpose is allowed, which categories have limits and what evidence is needed, including how tips, shared meals, mileage and foreign-currency costs are treated.

A policy that leaves common situations ambiguous produces disputes and makes fraud harder to distinguish from confusion. Approval should be more than a manager clicking a button, because the business purpose, date, amount, attendee and supporting document should be checked against the trip or project, and a manager may know that a meeting happened but not that the claimed meal was already paid on a company card, so finance should reconcile payment channels.

Duplicate claims can cross systems: one employee pays by corporate card and also submits the same bill for cash reimbursement, or a receipt might be attached to two separate reports. Use amount, merchant, date and receipt image to find matches, then ask for an explanation, remembering that legitimate shared expenses can produce similar-looking records.

Inflation can be subtle, as a person may add a zero to a taxi receipt or claim more mileage than the trip involved, so compare with routes and reasonable ranges without pretending a map proves the exact journey, since a detour for work may be valid. Fabricated receipts can be convincing, because digital templates and editing tools make a plausible document easy to create, so cross-check card statements, merchant details and invoice numbers when a claim is material or suspicious.

Focus on discrepancies and supporting evidence rather than a rigid algorithm, do not collect unrelated private data merely to satisfy curiosity, and use a proportionate, confidential process. Split approval roles where feasible, since an employee should not approve their own reimbursement, and senior executives need an independent review route too; if one small-business owner handles everything, periodic bank and card reconciliation can provide a compensating check, and exceptions should be documented rather than assuming seniority makes review unnecessary.

Look for patterns across time: a series of claims just below a receipt threshold may warrant a closer look, but could also reflect normal travel. Repeated weekend charges, duplicate merchants or unusually round amounts are signals, not verdicts, so combine them with actual schedules and documents.

Protect people during an investigation by limiting access to the allegation, preserving original records and avoiding gossip, and follow employment law and the organisation's disciplinary procedure, giving the employee a fair chance to explain a discrepancy, because a false accusation can harm a career and the company's reputation. A confirmed case may call for repayment, discipline or legal action, depending on facts and jurisdiction, so avoid promising an automatic firing or criminal charge, check employment rules and evidence with appropriate advisers, and correct the accounts and recover funds through lawful means.

For an illustrative metric, confirmed invalid claims worth $6,000 out of $1 million reimbursed equal 0.6% by value, but that rate depends on detection and classification, and a low number can mean good controls or weak checking, so track the number of claims reviewed, errors corrected and repeat causes. Expense fraud is a deliberate misuse of reimbursement, not a label to apply to every anomaly, and clear rules, independent review and reconciliation reduce risk while protecting cash and staff alike.
