Checkout King

Checkout King controls what customers see at checkout — delivery options, payment methods, discounts, and whether an order can be placed.Write rules once — hide express shipping over 5kg, block PO box addresses, rename a payment method, discount large orders — and they apply automatically.The simulator shows which rules fire on a test cart before it goes live, and warns when rules contradict each other.Rules run on Shopify's infrastructure, so checkout keeps working even if we go down.
