A padded or fictitious invoice rarely announces itself. It slips into the same stack of routine bills your company processes each month. Knowing how to spot this issue before and after fraud occurs can help you respond promptly.
What is fraudulent invoicing?
Fraudulent invoicing occurs when someone submits false, inflated or duplicate charges to collect money a business does not owe. What separates it from a billing error is intent.
A clerk who enters an amount twice has made a mistake. A supplier who knowingly bills for goods never delivered has committed fraud. The distinction matters because proving fraud requires evidence of a deliberate misrepresentation rather than a simple error.
Which schemes drain company funds?
Invoice fraud can take several recognizable forms, and each exploits a different weakness in the way businesses approve and pay bills.
- Shell-vendor billing, where an insider approves invoices from a supplier that exists only on paper
- Inflated charges from a genuine vendor that overstate quantities, hours or unit prices
- Duplicate submissions of one charge, timed so a busy department pays it twice
- Payment redirection through business email compromise, where an outsider posing as a known supplier asks that funds move to a new account
Although these schemes differ, they all rely on bills appearing routine enough to avoid immediate scrutiny. Recognizing the warning signs behind each tactic can help your business spot unusual billing activity before it sends additional funds.
Can you prevent this internally?
Most invoice fraud succeeds because one person controls too much of the payment process or key steps go unchecked. The following controls can help reduce those opportunities:
- Separating responsibility for approving invoices, adding vendors and releasing money
- Three-way matching that compares the bill, purchase order and receiving record before funds are issued
- Approval thresholds that require a second reviewer for larger or unusual funds
- Positive pay with your bank, which flags checks and transfers that do not match approved payment information
Even well-designed procedures depend on consistent use. Regular training and periodic reviews help employees recognize suspicious activity and report it immediately.
What are your legal options if this happens?
You may have grounds to file a civil fraud claim, which generally requires proving that someone knowingly made a false representation, you reasonably relied on it and your business suffered a financial loss as a result. If a legitimate supplier overbilled you or failed to honor the terms of a contract, a breach-of-contract claim might be the more appropriate course.
Your response can also vary based on the source of the fraud. An employee who created a fictitious vendor may face claims for breach of the duty of loyalty and conversion, along with a criminal referral for theft. If an outsider redirected your payment through deception, contacting your bank and law enforcement promptly may help limit the damage.
Time is another important factor. Depending on the type of claim, Illinois law may allow up to five years to file certain fraud-related lawsuits, and the filing period may not begin until you discovered or reasonably should have discovered the wrongdoing.
