What is fraud prevention?

Fraud prevention is the process of detecting, stopping, and reducing fraudulent or unauthorized activities in an eCommerce business. It uses security controls, transaction monitoring, authentication, and data analysis to identify potentially risky activity before it causes financial or operational loss.

In B2B eCommerce, fraud prevention can include:

• Transaction monitoring – Identifying unusual payment amounts, locations, or purchasing patterns.
• Identity and account verification – Confirming that customers and business users are legitimate.
• Payment authentication – Using methods such as 3D Secure or other verification mechanisms when appropriate.
• Fraud scoring – Assessing transactions based on multiple risk signals.
• Address and order checks – Identifying suspicious shipping, billing, or ordering patterns.
• Account security – Using strong authentication, access controls, and monitoring.
• Manual review – Sending high-risk orders to staff for additional verification.
• Chargeback monitoring – Identifying and responding to potentially fraudulent payment disputes.

For example, if a newly created business account attempts an unusually large order using a payment method that triggers several risk indicators, a fraud prevention system may flag the transaction for additional verification before fulfillment.

Effective fraud prevention should balance security with customer experience because overly aggressive controls can incorrectly block legitimate customers. Businesses should also follow applicable payment, privacy, and data-security requirements.
