MODULE 05 / LESSON 05
Discrepancies, Fraud Prevention & Investigations
Detect loss without jumping to accusations, preserve evidence and design internal controls that work.
Understand the principles, apply them to hypothetical retail operations, and distinguish evidence from assumptions. This is independent, unofficial educational content—not a professional credential.
1. Separate error, loss and misconduct
Differences may arise from miscounts, mapping errors, unrecorded waste, supplier errors, process gaps or intentional wrongdoing. A discrepancy is an indicator for investigation, not evidence of a particular employee’s intent.
Build a hypothesis list and test each one against transaction and physical records.
2. Common operational exposure points
Watch exception patterns in refunds, voids, price overrides, fuel-sales reconciliation, lottery tickets, scratch-off books, gift cards, vendor credits, checks and cash handling. These are risk areas, not proof of criminal activity.
Analyze frequency, timing, operator and supporting evidence; compare to normal transaction volume.
3. Separation of duties and oversight
Ideally, purchasing, receiving, reconciliation, refund approval, vendor changes and payment authorization are separated. Small businesses may lack staffing; compensate with owner review and tamper-resistant audit logs.
Example: a supervisor who can change supplier bank details should not also approve payment without an independent check.
4. Cash checking and checks received
A check-cashing business must assess authentication, settlement timing, returns, liquidity and applicable legal/AML obligations. A bank deposit entry is not proof a check has finally cleared. Obtain professional legal and compliance guidance before operating check-cashing services.
Scenario: a check presented Friday may create liquidity exposure until a return window or final settlement is resolved.
5. Investigating responsibly
Preserve original records; limit access to sensitive information; document when/where the exception occurred and who handled records; use consistent, private interviews; allow responses; avoid retaliation or prejudgment. Escalate suspected crimes or safety concerns appropriately.
Do not publish names, recordings, customer transactions or unsupported allegations on your public website.
6. Corrective action and management accountability
Not every issue calls for discipline. Correct inadequate training, broken procedures, insufficient coverage, unclear delegation or flawed system settings. When misconduct is substantiated, follow written policy and applicable law consistently.
A manager’s behavior and overrides should be reviewed with the same evidence standards as cashiers.
7. Case review: recurring voids
A store has 40 voids under one account. First normalize for transaction volume; inspect reason codes, manager approval, timing, receipts and video only when lawfully available. Cross-check policy. The correct outcome might be legitimate corrections, training gaps, control abuse or unresolved uncertainty.
Design exception thresholds and independent review instead of blanket accusations.
