AP Security Risks and How to Mitigate Them

When it comes to accounts payable invoice processing, there’s always a subset of individuals looking to exploit weak spots for financial gain. From fake invoices to phishing schemes, AP fraud can be costly, damaging, and disruptive. Identifying these risks and implementing strong safeguards is essential for protecting your business.

If you’re in Accounts Payable department, you know payment fraud, unauthorized transactions, and data breaches are becoming more common. In fact, a recent survey from J.P. Morgan found that 71% of organizations faced payment fraud attacks! And with AP fraud causing an average 5% hit to revenue, this isn’t just an occasional issue—it’s an ongoing threat. Much of this risk comes from weak spots within the company, like employee fraud, and external threats, such as phishing scams. Unfortunately, companies using manual AP processes often face even more exposure, leaving their finances vulnerable to theft, error, and misuse.

 

Key Takeaways 

• Automate AP Processes: Reduces manual errors, fraud, and improves security.

• Set Approval Workflows: Enforces checks to prevent unauthorized payments.

• Use Role-Based Access: Controls who can view or edit AP information.

• Monitor Vendor Details: Regular verification prevents fake vendor fraud.

• Switch to Digital Payments: Lowers risk of check fraud and improves traceability.

 

Why AP Automation is Crucial to Tackling Real AP Security Risks 

For finance teams, managing Accounts Payable (AP) security risks is more than just an operational task—it’s a fight against rising fraud and data threats that impact the bottom line. From unauthorized payments and phishing scams to invoice fraud and duplicate billing, AP security risks can cost businesses a significant portion of revenue, especially when manual processes are still in place. 

AP automation directly addresses these threats by tightening controls, boosting visibility, and introducing safeguards that manual workflows simply lack. Imagine an AP process where every transaction is verified in real-time, vendor information is consistently updated and validated, and role-based permissions restrict access to sensitive data. AP automation makes this a reality, helping organizations reduce unauthorized transactions, prevent duplicate payments, and safeguard vendor relationships. In a world where financial crime is only increasing, automating AP isn’t just an upgrade—it’s essential for defending your company’s financial health. 

 

Understanding Security Risks in Accounts Payable 

Security threats in Accounts Payable come from both inside and outside the organization. Let’s look at these in more detail to understand where vulnerabilities lie. 

 

Internal Risks 

Internal threats in AP often arise when employees have unchecked access or when there are gaps in verification processes. Here are some common ones: 

 

False Billing

False billing happens when employees create fake vendor accounts or phony invoices to pay themselves. Without strict controls on vendor verification, these fake invoices can slip through and become a major drain on resources.

 

Invoice Fraud and Fraudulent Payments

In some cases, employees tamper with legitimate invoices to authorize excessive or unauthorized payments. Without separation of duties and clear approval workflows, these unauthorized payments can go undetected, leading to unexpected losses. 

 

Check Fraud

Paper checks remain widely used, but they’re easily tampered with. Fraudsters can alter check details or even forge signatures, leading to unauthorized withdrawals. Did you know that according to the 2023 AFP Payments Fraud and Control Report, 63% of companies using paper checks have been affected by check fraud? This is a significant liability for any organization. 

 

ACH Fraud

ACH fraud involves unauthorized electronic payments. If your AP team doesn’t have dual approval for transfers, fraudulent ACH payments can reroute funds to unauthorized accounts, sometimes even outside the country, making it almost impossible to recover the lost funds.

External Risks 

External attacks often target AP staff through social engineering tactics like phishing scams. Here’s a breakdown of the common risks: 

Phishing Scams

Phishing is when scammers impersonate executives, vendors, or finance managers to trick AP staff into sharing sensitive information. 

Duplicate Payments

Human error or lack of verification tools often leads to duplicate payments, where vendors are paid twice for the same invoice. These mistakes can be costly, inflate budgets, and lead to endless follow-ups to recover the funds. 

Unapproved Vendors

Using unapproved vendors is risky because they may not go through strict vetting. Payments to unauthorized vendors can easily lead to fraud, especially if no one questions vendor legitimacy before payment processing. 

 

Additional AP Risks to Watch Out For 

• Cybercrime: Cyberattacks are only increasing, with projections of a global impact of $10.5 trillion by 2025. Cybercriminals target AP systems, exploiting weak passwords or system vulnerabilities to steal funds or data. 

• Dependence on a Small AP Team: When only a few people handle AP, risks increase, especially if they aren’t well-trained in fraud detection. Without proper accountability measures, fraud can go unnoticed. 

• Staffing Challenges: Temporary or inexperienced staff can overlook red flags, make data entry errors, or process unauthorized payments. High turnover or lack of training only heightens these risks. 

• AP Process Errors: Manual data entry is one of the leading causes of AP errors, creating opportunities for fraud. According to J.P. Morgan’s 2022 AFP Payments Fraud and Control Survey, found that 71% of companies view manual entry as a vulnerability. 

 

The Impact of Manual Processes on Security 

Using manual AP processes isn’t just a time-consuming constant hassle; it’s also a serious security risk. According to the Association of Certified Fraud Examiners, companies lose around 5% of their revenue to fraud each year. Here’s why manual processes expose your business to such risks:  

Security Risks	Impact of Manual Processes
Increased Fraud	Harder to monitor without automated checks
Cybercrime Vulnerability	More exposure with unprotected records
Frequent Errors	More common without automated verification tools
Financial Losses	Higher costs due to slow, error-prone processing

 

Consequences of Relying on Manual AP 

• Greater Vulnerability: Manual data entry lets employees bypass checks, creating unauthorized payments and invoices—an easy target for fraud. 

• Financial Drain: Duplicate, inaccurate, or unauthorized payments cause financial losses that add up quickly. 

• Lack of Traceability: Manual record-keeping lacks detailed audit trails, making it hard to trace back unauthorized activities or errors. 

 

Mitigation Strategies through AP Automation 

Many companies are now turning to AP automation to secure their payment processes. By digitizing and automating AP, businesses can create controlled, traceable, and transparent workflows that reduce security vulnerabilities. Here’s how automation works to keep your AP secure. 

 

Key Benefits of AP Automation 

Automated Approvals

Automation enforces approval workflows, ensuring that every invoice is checked and verified before payments go out. With every invoice following a documented path, it’s much harder for unauthorized payments to slip through. 

Real-Time Reporting and Audits

Automated systems provide real-time data and audit trails. For instance, automated alerts can notify the finance team if a payment exceeds certain limits, giving you a chance to stop fraud before it happens. 

Clear Role-Based Access

Automation allows role-based access, ensuring only authorized users handle sensitive AP information. By separating roles (like invoice creation and approval), automation minimizes the chances of fraud by limiting access. 

Switch to Secure Payment Methods

Transitioning from paper checks to secure electronic payments (like ACH and wire transfers) reduces check fraud risk. Digital payments are easier to track and validate, making them a safer choice. 

Integration with Accounting Software

Automated AP solutions can integrate directly with your accounting software, creating a consolidated view of all payment data. This integration helps detect duplicates, cross-reference payment histories, and flag discrepancies early on.
