About this app
Shopify has no real minimum or maximum order setting. Theme tweaks and cart messages get skipped by Shop Pay and other express checkout buttons, so a $20 order slips past your $50 minimum. Mastiff enforces the rule at checkout itself: minimum order quantity (MOQ), max quantity, minimum purchase amount, max order value, per-customer caps, and case-pack multiples for wholesale and B2B. Scope rules to a product, variant, collection, or whole cart, then test in the simulator before publishing.
