Why are event payments vulnerable to fraud?

Events combine changing vendor populations, large deposits, tight deadlines, many approvers, travel, last-minute requests, and domestic or international payments. Those conditions make impersonation and exception requests appear plausible.

What is the most important control for a vendor bank-account change?

Pause the payment and independently verify the change through a known contact method. A familiar-looking email should not be enough to replace previously verified banking information.

How can event teams prevent duplicate invoice payments?

Centralize invoice intake and compare vendor, invoice number, amount, date, and supporting documents before approval. Exact duplicates should be blocked, and near matches should be routed as exceptions.

How should payment responsibilities be separated?

The same person should not be able to create or materially change a vendor, approve the related invoice, and release the payment without an independent review. High-value and exception payments should receive additional approval.

What should an event payment incident response plan include?

The plan should identify who can pause payments, suspend vendor changes, contact the bank or payment provider, preserve evidence, notify internal teams, verify the legitimate vendor, and document the control failure.
