Your accounting team receives an email from a longtime vendor asking you to send funds to a new bank account. The request looks legitimate, so the transfer goes through. Days later, the vendor contacts your business and says the invoice is still unpaid.
Business email compromise can turn what seems like a routine transaction into a banking dispute. Although the fraud begins with a deceptive email, responsibility may depend on more than the email alone.
How these schemes work
Business email compromise uses trusted business relationships to redirect legitimate transfers. Some situations that can lead to a banking dispute include:
- A vendor sends updated payment instructions.
- An email appears to come from a company executive requesting an urgent wire transfer.
- Your business receives an invoice that appears to come from a trusted supplier.
- Someone intercepts an email chain and changes payment instructions.
- Someone sends fake closing instructions that redirect funds to a different account.
Each situation appears legitimate at the time. You may not discover the problem until the intended recipient tells you the funds never arrived.
Why banking disputes may follow
Once the money leaves your account, the fraudulent email is no longer the only issue. The focus may turn to the banking transaction itself. For example, questions may arise about whether your business authorized the transfer or whether the bank followed the security procedures tied to your account.
The dispute may also involve the terms of your account agreement or the bank’s response to unusual account activity. Because every transaction is different, responsibility will depend on the specific facts.
What this may mean for your business
Business email compromise has become a common threat because it targets routine business transactions and trusted business relationships. A single fraudulent transfer can interrupt vendor relationships, disrupt cash flow and create questions about responsibility after funds leave your account.
Not every fraudulent transfer creates the same legal issues, and not every banking dispute reaches the same outcome. How your business authorizes a transfer and how the bank handles it can both influence who bears responsibility.
As payment fraud continues to evolve, businesses will likely face more than cybersecurity concerns alone. A single fraudulent transfer can also raise legal questions, making the banking transaction just as important as the deceptive email that started it.
