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.
The app automatically cancels 'high-risk' orders, send a cancellation confirmation to the customer (optional), restocks the inventory, and refunds/voids the customer's payment (if any). While Shopify automatically flags high-risk orders for you, it doesn't cancel them - you still have to go through your list of orders manually.
- Block or hold orders from bad customers you've already identified.
- Discover bad customers that you didn't even know existed.
- Auto group customers with multiple accounts (e.g. different emails).
- Easily block any customer without needing complex fraud rules.
- Automatically deal with fraudulent orders
- Re-stock inventory - when an order is canceled, FraudBlock restocks the items
- Automatic refunds - automatically refund/void the customer's payment
- Optionally send an email notification to the customer and/or the store admin
