About BlockCart: Checkout Validation

Block bad-fit orders before they create cancellations and fulfillment work. Build no-code cart and checkout rules with multiple AND/OR conditions. Set minimum order quantity (MOQ), minimum cart value, and maximum quantity or value limits. Restrict products or collections by ZIP code, postal code, country, customer tag, login status, or company. When a rule matches, BlockCart stops checkout and shows a clear custom error so the buyer can fix the cart and continue. Set minimum order quantity, cart value, and maximum order limits. Restrict products or collections by ZIP code, country, or customer tag. Combine multiple conditions for precise cart and checkout rules. Enforce B2B eligibility by customer tags, login status, or company. Show custom error messages when an order is blocked. Show more Show less
