Mastiff: Order Limits & MOQ

Set MOQ and order limits with no code. Prove any rule in the simulator before you publish.

Wholesale buyers slip under your minimum. Resellers clear your drops. Promo abusers stack tiny orders. Mastiff blocks all three inside Shopify's own checkout validation, express wallets included. Set your first rule in under a minute, no code. Five rule types: min and max quantity, min and max order value, sell in multiples. Scope each to a product, variant, collection, or cart. Test any cart in the simulator first. What it shows is what checkout enforces.

• Enforce MOQ, max quantity, order value, and case-pack multiples at checkout
• Test any cart in the simulator before you publish, no surprises when it's live
• Scope any rule to a product, variant, collection, or whole cart.
