Stop invalid orders with checkout rules for order limits, ZIP codes, products, and B2B buyer restrictions.
About the BlockCart: Checkout Validation
BlockCart helps you stop invalid orders by setting up checkout validation rules that prevent bad-fit purchases before they happen. Create cart and checkout rules using multiple AND/OR conditions to control order limits, restrict products by location, and enforce B2B requirements.
Set minimum order quantity (MOQ), minimum cart value, and maximum quantity or value limits for your store. Restrict specific products or collections based on ZIP code, postal code, country, customer tag, login status, or company information. When checkout rules are triggered, customers see clear custom error messages explaining what needs to be fixed in their cart.
Perfect for stores that need to block orders from certain locations, enforce B2B eligibility requirements, or prevent fulfillment issues caused by order quantity restrictions. Build no-code validation rules that work automatically at checkout, reducing cancellations and unnecessary fulfillment work.
