Smart Cart Limits & Validation

Enforce step quantities & bulk rules with native speed.

Stop losing money on small orders and broken case packs. Smart Cart Limits gives you full control over what customers can check out. Whether you are a B2B wholesaler needing to sell by the case, or a store protecting margins with step order quantities, this app handles it securely. Smart Cart runs directly on Shopify's backend using native Functions. This ensures validation is robust, secure, and reliable, without impacting your storefront's visual loading speed.

• Strict Quantity Rules: Prevent checkout unless specific Step quantities are met.
• Sell simply: force customers to buy in multiples (e.g., packs of 6, 12, 24).
• Secure, server-side logic powered by Shopify Functions.
