The Accounts Payable Department (AP) is responsible for most business operations, handling all accounts payable functions from processing invoices and issuing checks. Regrettably, such an absolutely basic function can thus become seriously hit by financial fraud. Understanding why AP teams are vulnerable is an essential step in creating sturdy defenses.
The Vulnerability: Why AP is a Target worthy of Investment
AP’s susceptibility to fraud mainly stems from its access to corporate funds and vendor data. That access creates three major weaknesses:
Segregation of Duties (SoD) Failure
In the case of smaller organizations or ones with fewer AP staff, a single member manages so many administrative tasks—such as the generation of purchase orders, reception, vendor registration, invoices, setting up vendors and payment processing, etc. This division of responsibilities enables one person to create an artificial vendor, and to steal money and direct resources for their own gain.
Reliance on Manual Processes Continue to Depend on Paper Invoices
Despite the drive toward digital transformation the AP team is still relying on paper invoices, email approvals and manual data entry. On the other hand, with the widespread adoption of cloud capabilities. This reliance creates a setup in which invoices can be duplicated, inflated, or modified without raising any automated alarms. High transaction volumes lead to ‘alert fatigue’ or employees forgetting subtle sign-of-impending trouble.
Human Factors in Vendor Management
A large part of AP fraud attacks came about because the vendor master file (VMF) contained information of approved suppliers. If a scammer establishes a fake vendor or tricks an employee into changing bank account details for a bona fide supplier—this would call it Business Email Compromise (BEC)—how about redirecting tons of cash into their own accounts? Frequent contact between AP staff and vendors exposes them to more sophisticated forms of social engineering.
The Answer is: Building a Strong Defensive System.
AP vulnerabilities can be mitigated only by a composite process improvement in technological solution with process improvement.
Implement Robust Cohesion
This is a critical action. At least, separate those who approve payments from those who process them and establish a third party accountable for reconciling bank statements. For any amendments in the vendor master file, establish two-factor authentication with independent approval.
Automate and Digitize Processes
Developing an AP automation system greatly reduces the opportunity for manual fraud. Such a process ensures that the financial transactions are automated so that if fraud could occur manually, it won’t be done manually for a few steps too fast. They work via Optical Character Recognition (OCR) that automatically scans and validates invoice information (which flags duplicate invoices), and applies checks for duplicates of invoices and ensures that digital approval workflows can be audited and authenticated by design. We eliminate paper processes.
Implement Continuing Monitoring and Analytics
This is not about waiting for annual audits to surface problems but using software tools for continuous monitoring of suspicious activities including:
- Multiple vendors with identical addresses or bank accounts.
- Invoices just shy of approval thresholds.
- Large volumes of strange transactions aimed at new vendors.
Provide more Security for Vendor Master Files
Treat your VMF like a secure vault by limiting who can access what, auditing vendors who don’t or for whom you don’t believe, and checking that all requests for a change in bank information come from trusted secondary sources – for example, calls made to known contacts rather than emails.
Once these inherent risks — especially when stemming from manual processes and poor segregation of duties — are realized, and procedures and solutions offered in their entirety to stop fraud from occurring, organizations will be able to turn their accounts payable departments from a threat to a place of safety against fraudulent activity.
FAQS
1. Why is the accounts payable (AP) team prone to fraud?
AP teams handle many invoices and payments with access to sensitive data, making them targets for fraud like duplicate payments or fake vendors.
2. What are common signs of fraud in AP?
Red flags include unusual vendor info, frequent invoice changes, missing documents, or payments just below approval limits.
3. How can organizations prevent AP fraud?
Use strong controls like multi-level approvals, segregation of duties, automated invoice checks, audits, and staff fraud-awareness training.
