Fraud 101

The first time an e-commerce merchant experiences fraud is always a rude awakening.

Until that first chargeback, online retailers are usually unaware that they’re responsible when it comes to fraudulent purchase liability.

With that in mind, we’ve created this educational hub.

Our goal is to help you grow as a merchant, and as a business, by understanding the payments ecosystem around e-commerce, and the intricacies that make it different from traditional brick-and-mortar retail.

Signifyd’s Reimbursement Policy

What’s Covered

We cover chargebacks connected with fraud or unauthorized charges, often due to:

  • Stolen account information (account takeover)

  • Stolen financial information

What’s Not Covered

We do not cover chargebacks due to errors made by the merchant, card processor, or shipper, like:

  • Item not received, not as described, or defective/broken

  • Refund not processed

  • Duplicate charges

As long as the chargeback meets the above criteria, we'll cover it and reimburse the full chargeback amount, plus any associated fees.
