Invoice fraud targets both freelancers and businesses. Knowing the common patterns helps you avoid becoming a victim on either side of the transaction.
1. Fake invoice scams targeting businesses
Scammers send invoices for products or services that were never ordered, hoping a busy accounts payable team pays without close review. Always verify an invoice against an actual purchase order or agreement before paying.
2. Invoice interception fraud
Fraudsters intercept email communication between a freelancer and client, then send a modified invoice with different bank details. Always confirm banking details through a separate channel — a phone call, not just email — before sending payment, especially for large amounts.
3. Overpayment scams
A 'client' sends payment for more than the invoice amount and asks you to refund the difference — only for the original payment to later bounce or be reversed, leaving you at a loss. Be cautious of any client requesting a refund of an overpayment before the original transaction has fully cleared.
4. Fake client scams
Scammers pose as new clients, request work upfront with a fabricated invoice or contract to seem legitimate, then disappear without payment. For new or unverified clients, consider requesting a deposit before starting work.
5. Spoofed invoice templates
Fraudulent invoices sometimes closely mimic a real vendor's design to trick recipients. Always double-check the sender's email domain and banking details rather than trusting visual design alone.
How to protect yourself
- Verify new clients before starting significant work.
- Confirm any changed payment details by phone.
- Keep a clear paper trail of every invoice and communication.
- Use consistent, recognizable invoice formatting so anomalies stand out.
Staying alert without being paranoid
Most invoicing relationships are completely legitimate. A few consistent verification habits are enough to protect yourself without adding unnecessary friction to normal business.
