Modern Approaches to Accounts Payable Fraud Prevention

‍

Fraudsters thrive on weak internal controls, manual processes, and gaps in human oversight, making accounts payable (AP) a prime target. Without proper safeguards, businesses risk falling victim to costly financial fraud that can drain resources and damage their reputation. Here are some of the most prevalent AP fraud schemes:

1. Check Fraud
   Despite the rise of digital payments, checks continue to be a primary target for fraudsters. Criminals alter payee names, forge signatures, or create counterfeit checks to siphon funds from businesses. Fraudsters sometimes intercept legitimate checks and modify the payment details before depositing them. Since checks offer limited real-time security measures, they remain one of the most vulnerable payment methods.
2. Business Email Compromise (BEC)
   BEC scams have surged recently, costing businesses billions of dollars annually. In this scheme, cybercriminals impersonate company executives, vendors, or employees, using spoofed email addresses or hacked accounts to request urgent payments. These fraudulent emails often instruct finance teams to reroute funds to fraudulent bank accounts via ACH or wire transfers. Because the emails appear legitimate, many businesses unknowingly approve large transactions before realizing they have been victimized by fraud.
3. Duplicate Invoices & Overpayments
   Fraudulent vendors—or even internal employees—may exploit weak oversight by submitting duplicate invoices for the same service or inflating invoice amounts. This can lead to businesses overpaying or processing multiple payments for a single transaction. Without proper invoice reconciliation, these fraudulent payments can go unnoticed for months, resulting in substantial financial losses.
4.  Unauthorized Vendor Changes
   One of the most sophisticated AP fraud tactics involves fraudsters manipulating vendor details. This can happen in several ways:

• Phishing attacks trick AP teams into updating legitimate vendor bank accounts with fraudulent ones.
• Internal collusion enables dishonest employees to divert payments to their personal accounts.
• Vendor impersonation scams involve fraudsters posing as suppliers and requesting urgent account updates.

Without rigorous vendor verification processes, businesses risk sending payments directly into the hands of fraudsters—with little chance of recovery.

The Impact of AP Fraud

1. The financial consequences of AP fraud can be devastating, but the damage goes beyond lost funds. Businesses that experience fraud also face:
   Operational Disruptions – Fraud investigations consume time and resources, delaying legitimate payments.
2. Regulatory & Compliance Risks – Failing to detect fraud can result in non-compliance penalties and audits.
3. Damaged Vendor Relationships – Mistakenly paying a fraudulent account can strain supplier trust and lead to service disruptions.

Fraud prevention isn’t just about stopping bad actors—it’s about protecting the integrity of your business operations. Implementing strong internal controls, automated fraud detection and employee training is essential to minimizing risk and ensuring secure, efficient payments.

5-Step Approach to Preventing Accounts Payable Fraud

Fraud is an ever-evolving threat, and businesses must take a proactive stance to safeguard their finances. Below is a structured approach to preventing accounts payable fraud—outlining key strategies to strengthen controls, detect suspicious activity, and minimize risk at every level of your payment process.

1.       Strengthen Internal Controls

A weak control environment makes businesses 85% more likely to experience fraud​. Strengthening internal controls is the first step to securing your payment workflows.

• Require dual approvals for high-value payments and vendor changes.
• Limit access to payment systems by setting strict user permissions.
• Conduct regular audits and reconciliation reviews to catch irregularities early.

 2.       Automate Fraud Detection

Manual processes leave gaps that fraudsters exploit. Companies that actively monitor transactions recover funds 40% more often​.

• Implement AI-driven fraud detection to flag duplicate invoices and suspicious transactions.
• Use real-time vendor verification to prevent unauthorized payment changes.
•  Leverage Positive Pay to detect and prevent fraudulent checks from clearing.

3.       Secure Payment Methods

Certain payment methods, such as paper checks, are inherently more vulnerable—fraud related to check tampering costs businesses over $ 115,000 per incident.

•  Reduce reliance on paper checks, the most vulnerable payment method to fraud.
•  Implement ACH solutions with built-in security features.

4.       Educate & Train Employees

Fraud often goes unnoticed due to miscommunication or lack of awareness​. A well-trained team is one of the best defenses against fraud.

•  Conduct regular fraud awareness training for employees handling payments.
• Establish clear reporting channels for suspected fraudulent activity.
• Foster a culture of vigilance—fraud prevention is a company-wide responsibility.

5.       Continuously Monitor & Adapt

Fraud tactics are constantly evolving, so fraud prevention strategies must evolve too.

• Utilize real-time dashboards to track payment activity and identify anomalies.
• Regularly review fraud trends and adjust controls in response to emerging threats.
• Set up alerts for unusual payment patterns to catch fraud before it escalates.
