Finance fraud is a major problem affecting businesses of all sizes and industries. One way that fraudsters can exploit a business is through its vendor master file. The vendor master file is a record of all the vendors that a business works with, and it contains critical information such as the vendor’s name, address, tax ID number, and payment terms. If this information falls into the wrong hands, it can be used to commit fraud against the business. In this blog, we will discuss how to ensure your vendor master file is safe from finance fraud.

The global cost of finance fraud is staggering. According to a report by the Association of Certified Fraud Examiners (ACFE), businesses lose an estimated 5% of their revenue to fraud each year. In the United States alone, this translates to a loss of approximately $4 trillion per year. The most common types of fraud include billing schemes, check tampering, and payroll fraud. Vendor fraud is also a significant problem, accounting for 28% of all fraud cases, according to the ACFE.

Our recent poll shows that 24% of AP teams review their vendor master file every month. 24% review it quarterly, 24% annually, and 28% never review it.

So, how can you protect your vendor master file from fraud? Here are some tips:

  1. Implement a strong vendor onboarding process

The first step in protecting your vendor master file is to implement a strong vendor onboarding process. This process should include verifying the vendor’s identity, conducting a background check, and ensuring that the vendor has the necessary licenses and certifications to do business. You should also require that all new vendors provide a W-9 form, which contains their tax ID number, to ensure that you have accurate and up-to-date information.

  1. Monitor vendor activity

When a new vendor is onboarded, it is important to monitor their activity to ensure that they are not engaging in fraudulent behavior. You can monitor them by reviewing invoices, purchase orders, and other documents related to vendor transactions. You should also monitor your accounts payable system for any unusual activity, such as duplicate payments or payments to unfamiliar vendors.

  1. Limit access to the vendor master file

Limiting access to the vendor master file is another way to protect against fraud. Only authorized personnel need to access the file, and access is granted on a need-to-know basis. You should also implement strong password policies and require that all users change their passwords regularly.

  1. Conduct regular audits

Regular audits are essential to ensure that your vendor master file is accurate and up-to-date. Audits should be conducted by an independent third party and include a review of vendor contracts, invoices, and payments. Any discrepancies or red flags need to be thoroughly investigated.

  1. Use technology to your advantage

Finally, you can use technology to your advantage when it comes to protecting your vendor master file. Many accounting software packages include features that can help prevent fraud, such as automatic invoice matching and approval workflows. You can also use data analytics tools to identify unusual patterns in vendor transactions.


In conclusion, protecting your vendor master file from finance fraud requires a multi-faceted approach. By implementing a strong vendor onboarding process, monitoring vendor activity, limiting access to the vendor master file, conducting regular audits, and using technology to your advantage, you can significantly reduce the risk of fraud. With the global cost of finance fraud estimated to be in the trillions of dollars, taking these steps is essential for the financial health of your business.
