Foxrate: Checkout Rules adds order enforcement Shopify checkout doesn't have: minimum and maximum order value, minimum quantities and case-pack multiples, blocked shipping countries, business-email-only checkout, and blackout days. Every rule runs as a Shopify Function inside native checkout, not a redirect. Turn rules on from one settings page in minutes, no code required. Built for B2B and wholesale merchants, useful for any store.

• Require a minimum and maximum order value, store-wide or B2B only.
• Require minimum quantities or case-pack multiples per line.
• Block shipping to countries you can't ship to, with an early warning.
• Restrict checkout to approved business email domains.
• Turn off ordering on specific days, in your store's time.
