Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBlox stops repeat chargebacks, refund abuse, and serial returners before they place another order. On install, Blox imports your order and chargeback history automatically, so customers with past chargebacks are identified from day one. Customers using multiple emails or accounts are merged into one profile. When one merchant flags a fraudster, the community-powered blocklist protects every Blox store.
FraudBlock automatically cancels orders that Shopify's built-in risk analysis flags. The order is cancelled, payment refunded, and inventory restocked before fulfillment. Whitelist trusted customers to bypass fraud checks. The cancellation log shows the risk reasons for each cancelled order — a clear audit trail of every action FraudBlock takes.
