Detecting Duplicate Invoices

The Cost of Duplicate Invoices and Why Prevention Is Better Than Audits

Duplicate invoices might be a small percentage of non-compliance, but their impact is costly and completely avoidable. According to the Institute of Finance and Management (IOFM), up to 3.6% of invoices processed by large companies are duplicates. For E&P companies handling tens of thousands of invoices annually, that can translate into millions of dollars in unnecessary payments. Of course many of these are caught through the use of extensive manual labor, but this comes with its own set of problems and very high costs.

How Duplicate Invoices Slip Through the Cracks

In high-volume environments, duplicate invoices can occur for several reasons:

• Clerical errors: Vendors or internal staff mistakenly submit the same invoice more than once.

• Invoice number changes: Slight variations in invoice numbers bypass simple duplicate checks.

• Manual processing mistakes: Overloaded AP teams may unintentionally approve duplicates, especially under tight deadlines.

The Hidden Costs of Duplicate Payments

• Direct financial loss: Overpayments directly impact cash flow and operational budgets.

• Cost of recovery: Reclaiming funds requires time-consuming collections efforts and often incurs legal fees.

• Collections risk: If the vendor is uncooperative or goes out of business, recovering funds becomes nearly impossible and can incur even more costly efforts.

Year-End Audits

Relying on end-of-year audits to catch duplicate invoices is inefficient and costly:

• Delayed discovery: By the time duplicates are found, the funds have already been paid out.

• High labor costs: Manual audits are time-intensive and often require expensive third-party support.

• Low recovery rates: Even with clawback clauses, success rates for recouping overpayments are typically low.
