Payment fraud refers to the fraudulent use of payment information (account-number, card information, etc) to obtain money, goods or services. B2B payment fraud specifically targets companies: fraudsters find a way to divert funds from a company’s finances. It can concern different payment methods: ACH, wire transfers, etc. 


B2B payment fraud takes many forms: CEO scams,wire-transfer scam, phishing, supplier fraud, etc. To summarize, it’s all the ways fraudsters can embezzle funds from a company.


One of the most common ways is using identity theft to change banking information and have money sent to fraudulent bank accounts. This type of fraud is difficult to detect: that’s why it’s crucial to have an automated solution like Trustpair that checks bank account ownership. Your Treasury team can handle payment processing with peace of mind and the confidence they’re paying the right merchants.

There are many explanations for the increase in payment fraud worldwide.


The switch of many financial institutions to digital banking is one of them. Indeed, online-banking – as well as mobile banking – and electronic payments have made it easier for fraudsters to divert funds, via cyberattacks. Although online-only operations have many advantages for corporations and banks alike, they require setting up additional security measures. 


The increased sophistication of scammers is also a factor. They’re more organized, specialized and can easily infiltrate payment systems to make payments to their own banking account. That’s why it’s crucial to have multiple layers of protection: online security defenses but also anti-fraud software to block the financial effects of fraud. 


In the US, the switch from check payments to electronic payment solutions is also an open door to payment fraud. Indeed, companies going paperless suddenly have a large amount of banking related data (merchant account numbers, account holders identity, etc) they have to handle to transfer funds electronically. This data needs to be managed – by a solution like Trustpair – to avoid fraudulent online payments and make sure finance teams send money to the right vendors. 

One of Trustpair’s key strategies in combating B2B payment fraud is integration with external international vendor data sources. These sources provide essential information to validate instantly the ownership of vendors’ bank accounts, ensuring the legitimacy of transactions. Trustpair relies on trusted external data and internal data such as client data mutualization or payment history. This enhances the accuracy and reliability of its fraud prevention efforts and ensures top-notch protection against fraud. Trustpair is the ultimate anti-fraud platform and will make fraud detection and prevention seamless.
