Safeguard Your Business Against E-mail Fraud

 Verify Account Information Before You Pay With ACH Prenotes

Business E-mail Compromise (BEC): A Growing Threat

 

Business E-mail Compromise (BEC) is one of the most financially damaging forms of fraud targeting businesses today. It typically involves a criminal posing as a trusted contact - such as a company executive, vendor or employee - who requests a change in payment instructions or initiates a fake payment.

Because these e-mails often appear legitimate and come from seemingly trusted sources, they can be difficult to detect without strong verification protocols in place.

In 2024:

77% of organizations experienced an attempted BEC scam

47% of BEC scams targeted ACH transfers

39% targeted wire transfers

The Role of Prenotes In Preventing BEC Fraud

An ACH prenote (short for pre-notification) is a non-monetary, $0 test transaction sent through the ACH network to verify the accuracy of a recipient’s routing and account number before a live payment is issued.

Why Use Prenotes?
Using prenotes adds a layer of verification that helps:

  • Confirm changes to vendor or employee banking information

  • Detect incorrect or fraudulent account numbers

  • Introduce a critical pause to validate payment changes with a known contact outside of e-mail

This small step can prevent costly mistakes and protect your business from losses and reputational harm.

 

How to Use Prenotes with Capital City Bank

The Capital City Bank Online Treasury Management platform makes it easy to implement prenotes as part of your payment process.

When to initiate a prenote:

  • When adding or modifying an ACH recipient in online banking

  • When entering or updating banking details for a vendor or employee in your accounting/ERP system

How to initiate:

  1. Submit a $0.00 payment to the recipient using the standard ACH process.

  2. Wait at least 3 business days before issuing a live payment.

  3. Our system will recognize the transaction as a prenote and process accordingly.

Note: Under NACHA guidelines, any errors with the prenote must be returned within 3 business days, giving you time to correct invalid or fraudulent account information.

 

Additional Ways to Protect Against BEC Fraud

  • Always verify account changes using a known phone number or other out-of-band method - not just e-mail.

  • Train employees to recognize red flags, such as urgent or unusual payment requests.

  • Implement dual control and approval workflows for payment changes.

  • Establish a policy requiring prenotes for all new or updated ACH instructions.
