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.
