CartHook

CartHook is a post-purchase upsell and revenue optimization platform designed for Shopify merchants. It enables brands to present highly targeted one-click offers immediately after checkout, without disrupting the buying experience. The primary purpose of CartHook is to increase average order value (AOV) and maximize revenue from existing traffic by intelligently extending each transaction with relevant add-ons.

CartHook provides a drag-and-drop funnel builder that lets merchants create customized post-purchase upsell and downsell flows based on products, collections, order value, or customer behavior. Offers are presented as true one-click upsells, using the customer’s existing payment method, so no additional checkout steps are required. The platform integrates natively with Shopify Checkout, supports major payment processors, and maintains accurate order and inventory data. Detailed analytics and A/B testing tools allow merchants to measure performance, optimize offer combinations, and refine targeting rules over time.
