Fraud prevention works best when controls are simple enough to run every month. A small business does not need a large compliance department to reduce risk; it needs separation, visibility, review and documentation at the points where funds leave the business.
1. Owner bank review
Owners should independently review bank statements, unusual transfers, ACH activity, check images and credit-card charges. This review should use bank-source information, not only accounting-system reports.
2. Vendor setup controls
- Require complete vendor setup forms.
- Verify tax ID, address and payment instructions before first payment.
- Review vendor changes separately from invoice approval.
- Search for employee/vendor address or bank-account matches when possible.
- Lock inactive vendors.
3. Payment approval and segregation
The same person should not be able to create a vendor, enter an invoice, approve payment and reconcile the bank account without review. Where staffing is limited, use owner review or outside bookkeeping oversight as a compensating control.
4. Payroll change review
Review new employees, terminated employees, direct-deposit changes, rate changes, bonuses, overtime and manual checks. Payroll fraud often hides in master-data changes rather than obvious payment entries.
5. Monthly reconciliations with evidence
Bank, credit-card, inventory, receivable and payable reconciliations should be completed on time and reviewed. Save evidence of the review, not only the final report.
6. A way for people to report concerns
Tips are consistently important in occupational-fraud detection. Small businesses should give employees, vendors and managers a practical path to raise concerns without routing everything through the person who may be involved.
7. Response plan before a crisis
Decide in advance who preserves records, who contacts outside counsel or insurance, who limits access, and who communicates internally. A calm first response protects evidence and reduces avoidable damage.
Use the Small Business Fraud Toolkit.
The toolkit helps owners document red flags, organize evidence, ask better questions and identify control gaps.
