MOQ Guard

Enforce minimum order quantities and override limits at checkout using variant metafields.

MOQ Validator lets you enforce minimum order quantities at the variant level using metafields. Apply rules only to products tagged with MOQ and optionally override limits with a custom “available override quantity.” Built with Shopify Functions, it blocks invalid quantities at checkout while keeping the buying experience smooth. Perfect for wholesalers and bulk sellers.
