Billing fraud continues to be one of the most common and often overlooked forms of occupational fraud. While the mechanics of the scheme can vary, the underlying concept is straightforward,Ìý an employee exploits vendor payment processes to redirect company funds for personal gain.
In many cases, these schemes are not highly sophisticated. Instead, they rely on gaps in oversight, trust in established vendors, and a lack of routine scrutiny over accounts payable activity.
How Billing Fraud Typically Occurs
Organizations often assume fraud requires complex manipulation, but billing fraud schemes are frequently built on routine processes that have gone unchecked. Some of the more common approaches include:
Shell Company Schemes
An employee creates a fictitious vendor, often structured to resemble a legitimate business. Invoices are submitted for services that are never performed, and payments are routed directly to the employee.
Duplicate Payments
This scheme leverages the duplication of legitimate invoices: one payment is issued to the legitimate vendor, while a second is redirected to the employee’s controlled account, often through ACH or EFT. In some cases, both payments reach the vendor, and the employee intercepts or redirects a refund.
Fictitious or Inflated Invoicing
Employees may either generate fake invoices or collude with external vendors, billing for goods or services that were never delivered or inflating legitimate invoices and sharing in the excess through kickbacks.
Key Red Flags to Monitor
- Duplicate or similar vendor names: Slight variations may signal an attempt to disguise a shell entity within the vendor list.
- Minimal vendor information: Vendors using only P.O. boxes or lacking a verifiable business presence warrant additional scrutiny.
- Limited or no online footprint: Absence may indicate a fabricated entity.
- Unusual invoice numbering patterns: Sequential invoices can suggest a fake operation; irregular sequences may indicate duplicate payments.
- Payments to multiple bank accounts: A sign of diversion.
- Unexplained increases in vendor spend: May indicate fictitious or inflated invoicing.
- Round dollar amounts: Can suggest fabricated billing.
A Practical Perspective
What we consistently see across organizations is not a lack of awareness but a lack of consistency. Controls may exist on paper, but they are not always applied with the discipline needed to detect subtle anomalies.
Billing fraud prevention is less about adding complexity and more about reinforcing fundamentals, including segregation of duties, independent vendor onboarding, routine analytics, and periodic reviews of vendor master files.
If it’s been a while since you have taken a closer look at your vendor population or accounts payable activity, now is a good time to revisit it. Bringing an independent perspective to your processes can often surface risks that aren’t visible day to day.
