What’s Accounts Payable Fraud?

Accounts payable fraud happens when someone manipulates your AP system to steal funds. Criminals can create fake invoices, alter payment details, or have someone on your team assist them. The identity of your legitimate suppliers can be stolen, making detection difficult until it’s too late.

Did you know?

Accounts payable fraud often involves "ghost vendors"—fake suppliers set up by fraudsters to steal company funds.

Types of Accounts Payable Fraud

Fake invoices

Fraudsters may create entirely fake invoices or alter legitimate ones to change payment details.

Duplicate payments

Duplicate invoices can trick your team into processing multiple payments.

Vendor impersonation

Cybercriminals can impersonate your suppliers by hacking their email addresses.

Internal fraud

Employees with access to your accounts payable systems can manipulate records.

Kickback schemes

Employees collude with suppliers to approve inflated invoices for personal benefit.

Phishing

Fraudsters use phishing emails to obtain login credentials to access your systems.

Warning Signs of AP Fraud

Unusual requests

Be cautious if a vendor suddenly asks for banking detail changes or urgent payments.

Invoices with no details

Fraudulent invoices often lack clear descriptions that match purchase orders.

High-value payments

Large payments without usual supporting documentation are suspicious.

Repeated small transactions

Patterns of low-value transactions can indicate hidden fraud.

Strategies to Prevent Accounts Payable Fraud

Perform a risk assessment

Analyze critical points and vulnerabilities in your AP process.

Implement internal controls

Segregate duties so that no single person controls the entire AP process.

Use vendor verification protocols

Establish a standard procedure for vendor onboarding with background checks.

Automate the AP process

Automation reduces human error and flags suspicious activities.

Audits

Frequent audits can help identify inconsistencies and catch fraud early.

Train your team

Constant training can help identify potential red flags surrounding fraud.

What to Do If You Fall Victim to AP Fraud

If fraud occurs, act quickly by contacting your bank, reporting to authorities, and conducting an internal investigation to identify weaknesses in your processes.
