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.

• Hide, rename, reorder delivery options, payment methods by cart, addr, customer
• Block checkout on rules you set PO boxes, postcodes, missing details
• Test rule against a sample cart before it goes live, and catch conflicting rules
• Automatic discounts on products, orders and shipping, with no discount codes
• Works on every Shopify store — Basic to Plus — not just Plus
