Vendors provide goods and services to help businesses develop products that they then sell to customers. An important step in this process is invoice payment, which has quickly become one of the leading sources of payment fraud, causing financial loss for thousands of businesses.
In general, the best way to prevent invoice fraud is to remain vigilant, train your staff to recognize it, use proper authentication practices, and double-check everything.
In this guide, we provide a more comprehensive overview of invoice fraud, how it works, and steps businesses can take to help prevent it from impacting them.

Simply put, invoice fraud is a fraud scam where businesses are deceived into paying fake invoices for nonexistent or overpriced goods and services or otherwise mistakenly sending payments to a scammer's account.
The high volume of invoices businesses often manage and the manual nature of the process have made invoice scams a popular method used by fraudsters to steal money from companies.
Deferred payments, often managed using invoices, are a popular payment method used by businesses because this approach helps companies manage cash flow effectively and improve their accounts payable turnover ratio.
However, businesses (and vendors) are increasingly moving away from paper invoices in favor of digital invoice payments.
We will cover this later in this post, but while this reduces the likelihood of paper invoice fraud occurring, digital invoice fraud can be just as tricky.
Invoice fraud attempts to take advantage of accounts payable departments and business owners by deceiving them into paying for goods and services they never received or at higher prices than contractually agreed to.
In general, fraudsters take steps to pretend to appear as trusted vendors or at least have fake invoices appear as real.
Here is a more comprehensive list of methods fraudsters use to execute invoice fraud:
Account takeovers are a common type of invoice fraud where a scammer gains control of a vendor's billing system – either by exploiting security vulnerabilities or social engineering – and sends fake invoices to a business, tricking them into paying for goods or services that aren't actually provided.
A business email compromise, resulting from a hack or otherwise, could make vendors susceptible to account takeovers.
Even if you have a strong relationship with your vendors, it’s important that you remain mindful of any behavioral changes in electronic communications and keep a close eye on inbound invoices for any suspicious signs.
Employee fraud occurs when a company’s own staff creates or approves fake invoices to steal money from the business.
This type of invoice fraud occurs when a business receives phony bills for products or services they never bought, created by scammers who are impersonating legitimate vendors to steal money.
What makes this type of invoice fraud difficult to detect is that the invoice may appear real – with information like bank account numbers, email account addresses, vendor account details, social media account URLs, and other info to help pass off the document as real.
Vendor fraud for invoice fraud occurs when a dishonest supplier sends a business inflated or false invoices for products or services, intending to illegally obtain more money than they're owed.
Bill padding is a fraudulent activity where a vendor inflates a bill or invoice with extra charges for goods or services that weren't actually provided in order to get more money than they should.
Duplicate invoices refer to a scam where a business intentionally sends several identical bill payment requests for a single expense, tricking them into paying multiple times for the same service or product.
Misdirection is an impersonation technique that occurs when scammers redirect payment for a legitimate invoice into a fraudulent account, typically by providing false banking details or by convincing a business to change their payment information.
As we covered in our first blog post, phishing in invoice fraud is when scammers use deceptive emails pretending to be from legitimate vendors, aiming to sneak past cybersecurity measures and steal sensitive information that allows them to issue or redirect payments fraudulently.
Phishing emails may move through your spam filters, so be extra careful when reviewing invoices received through email!
When it comes to invoice fraud, trust your instincts and stay sharp. If you're reviewing an invoice and something doesn't quite add up or seems off, there's a good chance your gut feeling is pointing you in the right direction.
A healthy dose of scrutiny, skepticism, and attention to detail is often your best line of defense against these crafty scams.
When in doubt, you can always reach out to a vendor provider via email or phone call to help verify that an invoice is accurate.
The following practical recommendations are some of the most effective invoice fraud detection and prevention steps you can take to spot a fake invoice:
Compare the “vendor” information and payment details on every invoice with the information you have on file to check for any discrepancies.
If you see a suspicious invoice with formatting or spacing issues that look off compared to what you ordinarily receive from a vendor, this is a red flag.
Common signs include a letterhead that looks like it was created with Adobe Photoshop, a template that looks like something you could pull from Google Images, grammar issues, or font and spacing that are inconsistent.
The invoice should line up with a purchase of goods & services you've made for the purposes of your business. This is where 3-way match validation capabilities can come in handy.
Vendors typically set clear expectations, dates, and payment processes with businesses they work with, so there should be very few surprises when it comes to processing invoices.
If there's a sense of pressure from the vendor to fulfill the invoice in a rushed manner, there is a high likelihood that a fraudster might be pretending to be your vendor and sending you a fake invoice.
Finance teams are often busy and, depending on your monthly vendor payment volume, taking extra precautions to ensure invoices you are receiving and paying are accurate
There are a few practical steps you can take to help prevent invoice fraud from impacting your business.
Pay close attention to the details of the invoice as mentioned above, verify directly with the vendor if the invoice was sent by them, and ensure the invoice provided matches the goods and services that you have purchased as part of your business operations.
Simply pick up the phone and call the vendor directly to confirm that the invoice was generated and sent by them.
Have regular staff training on how to detect common red flags of fraudulent/altered invoices using the practices mentioned above
Always use a 2-way or 3-way matching to verify and authenticate an invoice received for goods and services rendered. Ensure details on the invoice match your business records.
Social engineering in invoice fraud is when tricksters pretend to be your usual vendors or bosses to get you to send them money. If you put your business out there on public sites, scammers might be watching, ready to act like they're the real deal and take your payment.
