How to Identify Fake Invoices: Combating Invoice Fraud

Check the Clarity of the Logos

If the fraudster is not a part of your client’s company, chances are they are using scanned duplicate payment documents of the same invoice to steal from you. This is shown by the attributes of the logo on the invoice, which cannot be scanned and reused with the same clarity. This can be a simple and basic indication. Experienced accounts payable teams can easily check supporting documents, any different bank account, fraudulent activity, employee fraud, etc.

The Account Number is Changed

If the fraudster changes even one critical piece of information on a previously existing, legitimate invoice, such as a bank account number for an electronic payment process.

Once again, a keen eye can save the day. Your company should compare the print in critical fields to the print on the rest of the invoice of a big payout. Is there such a thing as a comparable font? Perfect match? Hitting the line as the other personal details are stated?

Furthermore, as an added measure of control, compare that field on the invoice to previous ones from the same vendor.

Invoices in Even Amounts

Fraudsters are more likely to frequently write even numbers while creating a fake invoice. Double-check it if you see it on the invoice because this frequently happens in fraud cases. You should raise red flags if you come across an invoice with even totals.

This is a further crucial sign of invoice fraud, claim fraud experts. Remind your company staff that being highly organized can be risky. Cybercriminals commit fraud but mostly forget to keep these small details while making payments request in check.

Separation of Responsibilities

No one should perform numerous sets of tasks that are incompatible with one another, according to the concept of segregation of duties. Allowing a single person to conduct financial transactions such as payments and then record them facilitates fraud.

In contrast, the principle of segregation of duties states that no single person should be charged with handling two or more competing sets of work. Those who select and onboard vendors are also not compelled to pay invoices. Furthermore, all operations must be examined or confirmed by a third party to eliminate prejudice and fraudulent behavior.

An automated procure-to-pay solution with approval procedures stating who authorizes bills and configured permissions ensuring that no one may do conflicting actions within the system could considerably help the division of duties.

Supplier Due Diligence

Fraudulent vendor bills may usually be avoided by properly identifying and onboarding new providers. When onboarding vendors, certain due diligence steps must be performed. Due diligence investigations may also include discovering whether the vendor is on any sanctions lists that would prevent them from doing business in the US.

An automated procure-to-pay system with a vendor portal requires you to collect such vendor master data as well as PO, invoice delivery options, and all supporting documentation from the start before processing payments to new accounts.

You can ensure that you only do business with genuine, fully compliant suppliers by requesting such information during onboarding and asking vendors to retain their data later. You may therefore regularly check their performance and financial condition during the length of the contract to guarantee that you are always protected against fraud and non-compliant behavior.

Double Check the Account Number on Duplicate Invoices

When a supplier emails you about new account details or a new account number appears on their invoice, utilize the second mode of communication to check this is legitimate – don’t email back, instead call or text them.

Everything must be prioritized and carried out fast and efficiently with fewer errors. Except to manually approve payments and approve invoices. Always check an urgent email, or a suspicious email from new suppliers twice. Verifying invoice information and invoice number is equally important. You must involve the prudential regulation authority in cases of fraud.

Prepare Your Bank Accounts for Payments

For larger organizations, this may comprise a database that connects to your bank account so that bills may be paid to the respectable and standard method. This requires entering supplier information into your banking app rather than manually entering it from the invoice each time for smaller enterprises. Also add supporting documents, documents of the purchase order, services rendered, legitimate goods, and accounts in a centralized place to appropriate parties to avoid financial loss.


The possibility of false invoices increases with time as it is extremely difficult to keep an eye on all the procedures. Invoice fraud is a constant concern to financial departments around the world to keep their company safe. However, if your organization is aware of the various common types of fraud, warning signs, and preventative techniques, you will be in the greatest position to mitigate its impacts when any new invoices are paid.

Stay safe and happy invoicing!
