Checkout Rules stops orders you can't or won't fulfil before they're placed. Pick one of 24 templates, such as an order minimum, a quantity cap or a delivery-country list, adjust it, and test it on carts built around its own limits. Each rule reads back in plain English and runs on cart changes, at checkout or both. Shoppers who break a rule see your message and can fix their cart. Rules run inside Shopify's checkout, so nothing is added to your theme.
