Set B2B checkout rules for minimum order amounts, order limits, case-pack quantities, payment methods, and delivery options. Checkout AI runs these rules in Shopify Functions, so merchants can enforce checkout validation without code or a third-party endpoint in the checkout path. Block sub-minimum carts at checkout. Require case-pack quantities (order in multiples of N). Hide credit cards for net-terms accounts. Hide, rename, or reorder delivery and payment options by company, location, custom

• No-code visual builder with AND/OR/NOT grouping and nesting — author complex B2B checkout policies without writing code or JSON.
• Three checkout Functions from one rule list: cart-checkout validation, delivery-option customization, and payment-method customization — installed and updated together.
• Draft rules in plain English with AI (you approve before they go live), start from ready-made B2B templates, and test every rule against a live sample cart before publishing.
