Bad Customer vs FraudBlock Fraud Preventionfor Shopify (2026)

Bad Customer and FraudBlock Fraud Prevention both target Shopify merchants seeking to reduce fraudulent orders and chargebacks, but they take fundamentally different approaches. Bad Customer leverages a shared history database of "bad" customers, identifying individuals with prior chargeback issues on other platforms and flagging orders from those individuals. This allows merchants to proactively identify and potentially cancel orders *before* fulfillment. It also flags orders based on address anomalies like PO Boxes or inconsistent billing/shipping locations. Its focus is on preventing fraudulent orders *before* they happen by relying on external data. FraudBlock, in contrast, reacts to Shopify's internal fraud analysis. Instead of relying on external chargeback history, FraudBlock *automatically* cancels orders that Shopify has already flagged as high-risk. It streamlines the cancellation process by automatically handling refunds, restocking inventory, and even sending cancellation notifications. This saves merchants time by automating post-order actions related to Shopify's own fraud detection. It's a reactive approach, relying on Shopify's algorithms to identify fraudulent orders and then automatically taking action to prevent fulfillment. Given the rating and review count difference, FraudBlock is perceived by users as more effective.
