Fraud checks that catch problems before they cost you

Most fraud isn't a dramatic scheme — it's a pattern that looks almost normal until someone actually compares it against history. Effective fraud checking isn't about suspicion, it's about consistent comparison.

The red flags worth building a process around

• A vendor's payment details changing without a verified request
• Invoice amounts just under an approval threshold, repeatedly
• New payees paid immediately, with no history to compare against
• Round-number transactions where itemized ones would be expected
• Approvals happening unusually fast for the dollar amount involved

None of these prove anything on their own. A vendor genuinely does change bank details sometimes. Invoices genuinely do land under a threshold by coincidence. The value of a fraud-review process is comparing today's transaction against the pattern of the last twelve months, consistently, so the exceptions that matter actually get looked at instead of drowned out by normal variation.

The organizations that catch problems early aren't the ones with the most suspicious staff — they're the ones who review the same handful of red flags on every transaction, every time, without fatigue setting in after the two-hundredth invoice of the month.
