Behavioral warning signs
Look for a person who never takes vacation, refuses to share tasks or gets defensive about reviews. Others live beyond their apparent means, complain constantly about money or control access to records in ways that block oversight. None of these proves wrongdoing, but together with weak controls they deserve attention.
Note changes in behavior too, like a sudden reluctance to hand over a task they previously welcomed sharing.
Common schemes
Fake vendors: someone sets up a payee they control and approves invoices to it. Check payments: altering the payee or amount, or writing checks to themselves. Payroll fraud: ghost employees, inflated hours or pay changes. Expense reimbursement: duplicate or personal claims. Skimming: pocketing cash before it is recorded as a sale. Misuse of company cards for personal buying.
Each scheme leaves a footprint in the books if you know where to look.
Red flags in the numbers
Warning signs include vendors with no phone number or a post office box, payments just under an approval limit, sequences of invoices with consecutive numbers from the same vendor, and unusual round-dollar amounts. Others are expenses growing while sales stay flat, bank reconciliations that are late or contain unexplained adjustments, and missing documents.
In payroll, check for employees you cannot identify, duplicate bank account numbers across employees and unexplained pay rate changes.
Tests you can run yourself
Once a quarter, sort your vendor list by total paid and review the top fifteen. Compare the vendor addresses and bank details with your employees. Look at payments made on weekends or after hours. Scan the payroll register against a current staff list.
Open the bank statement yourself, directly from the bank, rather than from a copy someone prepared for you.
If you suspect something
Do not accuse anyone or confront them first. Preserve records, restrict access quietly and speak with your attorney and a CPA experienced in forensic work. Handling it wrongly can harm a case or expose you to claims.
Review your insurance, since some policies cover employee dishonesty. Afterward, fix the control gap that allowed it, and consider a periodic outside review as an ongoing deterrent.
Building a culture that deters theft
Most fraud is opportunistic. People take what is easy and unlikely to be noticed. Make it visible that someone looks at the numbers: discuss reports openly, ask questions about unusual items, and rotate duties when possible. Provide a way to raise concerns, even if it is just a direct line to the owner. Clear policies on expenses, cards and personal use, written and acknowledged, remove excuses and make boundaries obvious.
Hire carefully in the first place. Check references for anyone who will handle money or books, and confirm the work history they describe. Background checks are regulated, so ask an attorney or a reputable screening provider about what you may do and what notices you must give.
Common questions
Should I bond or insure employees who handle money?
Ask your insurance agent about fidelity or crime coverage. It can help, but it does not replace controls.
Can I check a vendor is real?
Yes. Verify the address, tax ID form and contact details before the first payment.
Who do I report fraud to?
Start with your attorney, who can advise on police reports and notifying insurers.
