How to Keep Your Business Safe From Invoice Fraud

If you are in charge of accounts payable then it’s your responsibility to keep your business safe from invoice fraud.

Recently Facebook and Google were tricked out of $123 million in invoice frauds. But whether your business is massive or small, invoice fraud can cost you serious money.

According to the FBI, the amount of money that scammers attempted to steal through invoice fraud grew nearly 140% between 2016 and 2018. Overall, invoice fraudsters targeted more than $12 billion worldwide between 2013 and 2018.

In other words, if your company has not been the target of invoice fraud already then it likely will be in the future.

So as an accounts payable professional it’s critical that you understand what invoice fraud is, how it works and how you can keep your company safe from invoice frauds.

How Invoice Fraud Works

There are several types of invoice fraud. Some are intricate. Others are simple.

Here’s how the most common invoice frauds work.

Business Email Compromise

Business email compromise is a type of invoice fraud where a scammer poses as a vendor or business partner and convinces a company to pay for services that were never rendered. This is the type of invoice fraud that Google and Facebook suffered recently.

In a typical business email compromise invoice fraud, criminals take over or convincingly spoof the email address of your vendor or business partner.

They monitor the payment process communication between your business and the other party. Then they send a fake invoice or ask for a wire transfer for services or products rendered. Often, the business’s AP department doesn’t realize it’s fraud and releases the funds.

For example, one of your admins might receive several emails from an email address that appears to belong to a business partner requesting payment for legal services, with wire addresses at legitimate banks.

Your AP admin recognizes the email address and the name of the business partner. The amount due is in line with what the business partner typically invoices. So the admin releases the payment via wire or ACH to the scammer.

Unless you understand and are able to identify it, this sophisticated form of invoice fraud can continue for months or even years.

False, Inflated and Duplicate Invoices

While business email compromise is a relatively new phenomenon, there are simpler invoice frauds that have been around for centuries.

Unscrupulous vendors or suppliers can commit invoice fraud by knowingly submitting false, inflated or duplicate invoices.

False invoices are invoices for goods or services not rendered. 

Inflated invoices are invoices that are sent with amounts higher than what was agreed to.

And while duplicate invoices are sometimes issued by accident, duplicate invoices are fraudulent if issued knowingly with the intent to defraud – often with a different invoice number.

You need to know how to prevent paying false, inflated and duplicate invoices.

Collusion and Corruption

Perhaps the most insidious form of invoice fraud is collusion and corruption.

In this type of invoice fraud one of your employees colludes with a vendor or supplier to engage in the invoice fraud.

Together, the employee and vendor use duplicate, false or inflated invoices to defraud your company. The vendor then uses a portion of those funds as bribe payments to the employee.

For example, an operations manager hires a cleaning company for janitorial services at a contracted rate of $500/week. But the employee and vendor then collude to have the cleaning company send invoices for $1000 per week. The employee approves the invoices which then get paid. The cleaning company and employee split the extra $500/week.

This type of invoice fraud is particularly difficult to discover since it involves an insider.

How to Prevent Invoice Fraud

Invoice frauds can cost your company thousands or even millions of dollars.

As an accounting manager it’s your job to detect and prevent it.

Now that we understand the most common forms of invoice fraud let’s talk about detecting and preventing it.

Implement Internal Controls

It’s challenging to catch invoice fraudsters. And often impossible to recover money paid to them.

So the best strategy for avoiding invoice fraud is to incorporate safeguards into your accounts payable process to make invoice fraud as difficult as possible in the first place.

Start by reviewing and implementing the GAAP Principles for Internal Control Procedures.

Internal controls prevent fraud as well as clerical errors. Solid internal controls also reduce losses from theft of company assets. 

These principles include segregation of duties, controlling access to systems and assets, strict rules around authority to approve, record keeping and verification/audits.

But general accounting internal controls only get you so far.

Adopt AP Best Practices

To prevent invoice fraud you also have to adopt AP best practices.

Here are three AP best practices that will keep your company from becoming a victim of invoice fraud:

  • Receipt, contract or purchase order matching. Compare invoices against receipts, contracts or POs. You will not have a receipt for fake invoices. And matching invoice amounts to contracts or purchase orders eliminates the possibility of duplicate or inflated fraudulent invoices. To avoid internal collusion and corruption schemes be sure that the person matching is not the person contracting/approving (segregation of duties).
  • Vendor Name Verification. If you don’t recognize the company name on an invoice you need to dig into it. Do a quick Google search to make sure the company is real. Check the company name against your master vendor list or confirm with the approving manager.
  • Vendor Address Verification. Another common invoice fraud scheme is to send an invoice with the name and logo of a vendor or supplier you do business with – but with a different payable address. Unless you match the invoice address with the address on your master vendor list you will be sending payment to a scammer.
