5 ways to fight fraud with AP automation

Over the past few years, AP departments have been fending off payments fraud the way Luke Skywalker battles Darth Vader in Star Wars. It has been both a tough and challenging fight.

Since the pandemic began, bad actors have used societal changes and an increase in digital transactions to come up with numerous ways to separate companies from their cash.

In fact, PYMNTS reported “business email compromise (BEC) fraud attacks targeting invoices and payments rose 155% between Q2 and Q3 2020. A recent survey also revealed that nearly half of all organizations reported severe fraud attempts on their systems in 2021, and 15% suffered major financial losses as a result”.

While there are lots of ways fraud is perpetuated, there are several actions AP departments can take to minimize the chances of payments fraud.

1. Centralize invoice processing and payments with AP automation and payments

Much of AP’s fraud vulnerability comes from multifamily, CRE, and other real estate companies using decentralized paper processes across multiple properties. These leave gaps fraudsters can exploit.

For example, if each property manager for a multifamily company collects stacks of invoices, sends them to a corporate headquarters, and then leaves the puzzled AP team to sort through all the invoices, get them routed for approvals, and then paid with a paper check, there’s a lot of places a bad actor can insert themselves into the process. They could impersonate a vendor, send duplicate invoices, or target the paper checks.
With automated accounts payable processes, however, all invoices travel through centralized AP software, giving everyone – from property managers to CFOs – complete visibility into every step of from invoice ingestion to payment.

There are also audit logs and reporting. Invoices have a complete digital audit trail, showing who approved them and when. Invoice approval workflows are also visible, as well as whether they have been changed (and by whom). Many systems, like Nexus, also send alerts about duplicate invoices.

2. Segregate invoice responsibilities

While the AP automation and payments system has a lot of safeguards to help mitigate fraud, it’s important that the AP department take additional actions. Segregation of duties is one of the most important ones to implement.

For example, it’s important that employees who can change the Master Vendor Record are not the same folks that can approve or pay invoices. That makes it more difficult for an employee (or someone impersonating an employee through BEC) to slip in a fraudulent invoice or change a vendor address.

3. Be on the lookout for invoice fraud by employees and bad actors impersonating employees and suppliers

Another important control is to be on the lookout for invoice fraud from any and all sources. Three common scenarios are:

  • An employee’s account can be compromised, and the employee access is used to perpetuate fraud
  • The employee can be a bad actor themselves
  • A suppliers’ account can be compromised by a bad actor who then impersonates the supplier

In these situations, the bad actor can submit an invoice that’s already been paid, but claim it hasn’t been paid. They’ll provide new payment instructions and get the funds deposited into their own account.

Another common scheme involves an employee submitting a false invoice from a fake company in the Master Vendor Record that looks similar to an existing vendor. They’ll submit invoices for the new illegitimate vendor – with the hope that they won’t be discovered because their name is extremely similar to a real vendor.

AP teams must be on their guard and pay close attention to the details. Some AP systems, like Nexus, have reporting that can help them easily spot changes to any invoice approvals or payments that list company names, amounts, and dates, letting them see subtle differences immediately.

4. Automate change requests from suppliers or verify by phone

Making sure vendors are who they say they are is important to mitigating fraud as well. Some AP automation and payments companies have extra validations set up to make sure all their vendors’ data is verified.

For example, Nexus has a self-service supplier portal, NexusConnect, that vets suppliers automatically before they can sign up to send their customers invoices or receive electronic payments. It also checks to see if the supplier is not on the Office of Foreign Assets Control (OFAC) list to ensure the supplier is not under any sanctions. If they are, they are prevented from setting up an account.
After a vendor has been established in NexusConnect, anytime they attempt to make an account update – such as to their address, phone, company name – a new check will automatically be triggered.

5. Choose the most secure payment method to pay vendors

Cutting back on paper checks and favoring electronic payment methods can help reduce fraud, too. According to the Association of Financial Professionals (AFP), paper checks are targeted most frequently by fraudsters, and remain one of the biggest threats for AP Teams.

On the other end of the security spectrum are virtual cards, which are among the most secure payment methods. These one-time use cards are issued by a B2B payments company (like Nexus) and emailed to the supplier for the exact amount of the invoice(s) due.

Per the 2021 AFP Payments Fraud & Control Survey, virtual card payments represent only 3% of targeted payment fraud versus 66% for checks. ACH transactions fall somewhere in the middle for targeted payment fraud but it’s important to note that this is the fastest growing payment type prone to fraud.

Mitigate fraud with company-wide practices

While AP teams can help reduce the risk of fraud by adopting these practices, the entire company must also be vigilant. Don’t ignore common security protocols, such as multi-factor authentication and employee training. Combatting fraud is a team effort and everyone has to do their part.
