Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureBoomGate adds a validation layer to your checkout that decides which orders can be completed. Build conditional rules from cart contents, product details, quantities, customer tags, order history, and shipping or billing addresses, then block checkout with a clear custom message when an order doesn't qualify.
Checkout Guard helps merchants prevent invalid orders before they reach checkout. It allows merchants to define rules that block carts with incompatible items, such as mixed pre-orders and in-stock products, conflicting shipping types, or fulfillment restrictions. Rules are enforced at checkout so invalid orders are stopped before payment.
- Build custom checkout validation rules: min/max quantities, required tags & more
- Browse templates and select a predefined rule.
- Add custom error messaging in different storefront languages.
- Block pre-order + in-stock items being purchased together
- Block carts with conflicting shipping or fulfillment methods
- Block carts with products that must be purchased alone
- Block invalid or incompatible product combinations
