Enforce server-side checkout rules. Stop invalid orders and courier delivery penalties.

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. Stop unauthorized orders of sample kits without catalog items, and enforce B2B wholesale case multiples. Edge execution with zero theme code or store slowdown.
