What is accounts payable fraud?

Accounts payable fraud occurs when a company pays for goods or services never received. This type of fraud can be perpetrated in several ways but usually involves some sort of collusion between the vendor and an employee of the company. For example, a vendor may submit false invoices for payment, or an employee may approve payment for goods or services that were never delivered.

What are the three most common types of accounts payable fraud?

There are many types of fraud, and each has its red flags. However, there are some commonalities among the most common type of schemes. The following is an overview of the three most common types of accounts payable fraud:

Vendor fraud

Vendor fraud happens in several ways but usually involves some sort of collusion between the vendor and an employee of the company. For example, a vendor may submit false invoices for payment, or an employee may approve B2B payments for goods or services that were never delivered.

Check fraud

Check fraud occurs when someone uses a stolen or forged check to pay for goods or services. This type of fraud can be challenging to detect because the company's internal controls may miss the check. For example, a thief may steal a check from the mail and alter the check before depositing it into their bank account.

Expense reimbursement fraud

Expense reimbursement fraud occurs when an employee submits false or inflated expenses for reimbursement. This type of fraud occurs when employees have access to corporate credit cards or expense accounts. For example, an employee may submit a false receipt for reimbursement or charge personal expenses to a corporate credit card.

How could accounts payable fraud be committed?

There are several ways accounts payable fraud could be committed. For example, an employee could create false invoices and submit them for payment or alter legitimate invoices and increase the amount owed. They could also make payments to fictitious vendors or use company funds to pay personal expenses. If any of these fraud schemes occur, it can significantly impact your business's bottom line and cause financial losses. 

Accounts payable fraud can be challenging to detect, but there are some red flags that businesses should be aware of. For example, if you notice an increase in the number of processed invoices or payment processing to new or unfamiliar vendors, this could indicate something nefarious. It’s critical to have controls to prevent and deter fraud, such as requiring approval for all invoices over a certain dollar amount and conducting regular audits of the accounts payable process.

The payables fraud happens in business

  • Creating false invoices: This type of fraud occurs when a vendor creates an incorrect invoice for payment. This could include unexplained or unusual vendor invoices, inflated invoices, duplicate invoices or missing documentation for invoices. In addition, the vendor may collude with an employee of the company to have the invoice approved for payment. 
  • Check tampering: This type of fraud occurs when someone alters a check that the company has issued. Changes include increasing the payment amount or changing the payee.
  • Kickbacks and bribery: This type of fraud occurs when a vendor offers a kickback or bribe to an employee to approve payments on invoices.
  • Expense reimbursement fraud: This type of fraud occurs when an employee submits false or inflated expenses for reimbursement.
  • Ghost employees: This type of fraud involves approved payments to fictitious employees.
  • Late payments to vendors: Late payments to vendors can be a sign that the company is having cash flow issues.
  • Unusual payment patterns (e.g., round-dollar amounts, frequent payments to the same vendor): Unusual vendor payments may indicate that something is being paid for that should not be.  For example, unapproved or unusually large expenses: 
  • Changes in vendors or supplier bank account information: Changes in vendor or supplier bank account information can signify accounts payable fraud cover-up as funds are redirected elsewhere.
  • Employees resistant to changes in accounts payable procedures: Resistance to changes in accounts payable procedures, particularly those that complicate or eliminate how employees could commit fraud, could signal that someone is trying to protect a scheme.
  • Team members bypassing internal controls: Team members who bypass internal controls or override them altogether may be doing so to commit fraud.
  • Employees with excessive authority over accounts payable processes: Employees with excessive authority over accounts payable processes may have more opportunities to commit fraud.

The bottom line?

It’s crucial to be aware of these red flags to catch any potential cases of accounts payable fraud. By being proactive and looking out for these warning signs, you can help to prevent your organization from becoming a victim of this type of crime.

It is critical to be aware of fraudsters' various methods to commit accounts payable fraud. By understanding how these scams work, you can take steps to protect your organization from becoming a victim.

Detection and prevention of accounts payable fraud require a proactive approach:

Some standard accounts payable prevention measures include:
