Kairo lets you create post-purchase upsell offers that appear right after checkout. Customers can add products with one click, without re-entering payment details. Build offer sequences with the flow builder, set conditions based on cart contents or order value, and run A/B tests to find what converts. Customize your checkout (Shopify Plus), thank you, and order status pages with product upsells, social proof, countdown timers, discount codes and surveys. Includes a visual drag-and-drop editor.
