About this app
Shopify has no minimum or maximum order setting. Theme tweaks and cart messages get skipped by Shop Pay and other express checkouts, so a $20 order slips past a $50 minimum. Mastiff enforces rules at checkout: 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 cart, then test in the simulator before publishing. Email support, answered the same day.
