About this app
Stop bad-fit orders before they become fulfillment headaches. Create checkout validation rules that block unwanted purchases by ZIP or postal code, shipping address, products, collections, product tags, SKU, quantities, cart total, customer tags, login status, country, company, discounts, and cart attributes. Combine multiple conditions for local delivery, product restrictions, order limits, B2B rules, and customer eligibility. Show a custom checkout error message when blocked.
