A Guide to Accounts Payable Fraud Prevention
TL:DR
Accounts payable fraud often exploits weak supplier controls, unclear approvals and manual invoice handling. Prevention starts with stronger workflows, supplier validation, duplicate detection and an audit trail for every decision.
Inside the guide we cover:
- common types of AP fraud
- how duplicate invoices and suspicious payments happen
- why supplier controls matter
- how invoice matching reduces risk
- how automated approvals create an audit trail
An Author's Note:
We see AP fraud prevention as part of everyday financial control. Most risks do not come from one dramatic failure; they come from small gaps in supplier setup, invoice matching, approval routing and payment controls.
Why Focus on AP Fraud Prevention?
Accounts payable fraud is on the rise. Weak approval controls, supplier impersonation and invoice fraud can all lead to costly mistakes. Preventing fraud at the source with automation is one of the strongest lines of defence.
Common Types of AP Fraud
- fake or inflated invoices from real or fake suppliers
- invoice splitting to avoid authorisation limits
- collusion between staff and suppliers
- unmatched payments to non-approved suppliers
- duplicate payments and manual coding errors
