CartHook

One-click post-purchase upsells after Shopify checkout

#upsell#post-purchase#shopify#aov#subscription upsell

About the Tool

CartHook focuses on the post-purchase upsell window that opens immediately after a customer completes their initial checkout. Unlike pre-checkout upsells that add friction before payment, the post-purchase approach charges the same payment method with a single click after the transaction is already done. The customer is still in a purchasing mindset and has no re-entry barrier. For brands selling consumables, accessories, or complementary products, adding a relevant upsell after the initial purchase can lift revenue per order by 10 to 20 percent without increasing acquisition costs. CartHook integrates with Recharge for subscription upsell flows, allowing a one-time buyer to be converted to a subscription customer with a single click. The tool is limited to the post-purchase context and does not address in-cart or product page upsell opportunities.
