How to detect fake invoices before you pay them: a step-by-step guide
Fake invoices usually succeed because teams lack fast, contextual proof. Here’s how to catch them using repeatable signals.
Step 1: Verify vendor identity and history
- Check vendor bank details vs prior payments
- Confirm email/domain matches expected vendor patterns
- Watch for “urgent” pressure paired with account changes
Step 2: Compare invoice changes to what’s normal
If an invoice is “different” in a way your team can’t quickly explain, it’s a signal. Good fraud controls turn differences into reviewable evidence.
Step 3: Use automation for consistency
Vantirs fingerprints vendors using QuickBooks Online payment history and flags bank mismatches and spoofed email signals so your team doesn’t rely on memory.
