Claude Post Purchase shows one AI-selected upsell on the page that loads after checkout, before the order confirmation. From your dashboard, choose which products are eligible for upsell, set discounts, and exclude products or order types. Claude reads each order and recommends one product from your approved catalog. Customers accept with one click — no second checkout — or decline and continue. Built on Shopify's post-purchase extension. Reporting shows accept and decline rates per product.
