Checkout Order Booster adds a native upsell widget directly inside the Shopify checkout. Set a trigger by product, cart value, or show to all customers. Choose from card, compact, or banner layouts and attach a percentage or fixed discount to drive conversions. Everything runs natively in checkout — no redirects, no friction, just higher average order value.

• Native checkout and post-checkout upsells that don't interrupt the buy flow
• Smart triggers by product, cart value, or all customers
• Card, compact, and banner layouts to match your brand
• Percentage or fixed discounts to make offers irresistible
