Mastiff: Minimum Order Limits

Mastiff is an app on Shopify that allows ecommerce merchants to set minimum order amounts, quantity limits, and purchase limits at checkout without needing to use any code. It enforces rules such as minimum order quantity, maximum quantity, minimum purchase amount, maximum order value, per-customer caps, and case-pack multiples for wholesale and B2B purposes. Users can scope rules to specific products, variants, collections, or the entire cart, and test them in a simulator before publishing. The developer, EMERGENESIS LLC, provides email support with same-day responses.
