Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureSome orders should never happen: an accessory checking out without its base device, two products that can't ship together, or a bundle item bought again on its own. CartGate blocks these carts before checkout. Set rules by product, variant, tag, or collection, and choose to block the cart or warn the customer on the product page.
CartShield protects merchant profits by validating orders directly inside checkout using server-side Shopify Functions. Unlike legacy apps that rely on cart scripts bypassed by 1-click express wallets or browser tools, CartShield cannot be skipped. Prevent couriers from rejecting freight by blocking PO Boxes and parcel lockers.
- Block orders that break your rules.
- Limits hold at every checkout: Apple Pay, Shop Pay, direct links, and more.
- Stop card testing fraud by restricting cheap or suspicious order patterns.
- Prevent customers from buying incompatible products in the same order.
- Block PO Boxes and parcel lockers for heavy freight and restricted items
- Require qualifying catalog items to purchase discounted sample kits
- Enforce B2B wholesale case pack multiples like cartons of 6, 12, or 24
- Validate checkout server-side across express digital wallets and one-page flows
