As businesses approach year-end, payment activity increases and internal teams often work under tighter deadlines. This combination of higher volume and urgency creates an opportunity for fraudsters to exploit routine financial processes. End-of-year invoice fraud typically targets accounts payable teams and relies on impersonation, urgency, and small changes to payment instructions.
What is End-of-Year Invoice Fraud?
End-of-year invoice fraud is a type of business email compromise (BEC) scam in which criminals impersonate legitimate vendors, suppliers, or internal contacts to redirect payments.
Fraudsters typically attempt to trick organizations into:
- Sending payments to fraudulent accounts, or
- Updating vendor banking information under false pretenses
These scams often intensify during year-end reporting periods when payment activity is at its highest and internal controls may be under additional strain. Accounts payable departments, finance teams, and small to mid-sized businesses are common targets.
How the Scam Typically Works
Invoice fraud schemes generally rely on impersonation and urgency.
- A fraudster impersonates a known vendor or company executive
- The attacker sends an invoice or payment update request
- The message includes “updated banking instructions” or a “final payment notice”
- Language is designed to create urgency, such as references to year-end close, overdue payments, or tax deadlines
- Payment is requested via wire transfer or updated ACH instructions
These messages often appear routine and time-sensitive, they may be processed without additional verification.
Red Flags to Watch For
- Sudden changes to vendor payment instructions
- Slightly altered email addresses or domains
- Requests to bypass normal approval steps
- Urgent payment demands or confidentiality requests
- Invoices that don’t match expected billing patterns
How Businesses Can Protect Themselves
- Confirm payment changes using known, trusted contact information
- Require dual approval for vendor updates and high-dollar payments
- Use call-back verification procedures
- Limit access to vendor master file changes
End-of-year invoice fraud relies on urgency and routine workflow gaps. Taking time to verify even small changes can help protect your business from financial loss during high-activity periods.
