# Upsell Upselling is a monetization strategy that lets you sell additional products to users after they complete a purchase on the paywall. By offering upsells, you can increase average order value and long-term customer value without adding friction to the initial checkout. *** ### Payment Provider Support Upselling is currently supported only for Stripe. It is not available for Paddle due to limitations related to Paddle acting as the merchant of record. *** ### Supported Product Types Upselling works with: * One-time products * Recurring subscriptions Users can purchase upsells regardless of the product type they originally purchased. *** ### Stripe Upsell Button Upsells are implemented using the **Stripe Upsell Button** component. This component is similar to the Custom Button component, but instead of triggering navigation, it purchases the product connected to it when clicked. *** ### Placement and Flow The Stripe Upsell Button must be placed on a page that appears after the paywall. Upsells work by reusing the payment details from the original purchase. This allows the user to complete the upsell with a single click, without re-entering card details or re-authenticating the payment. *** ### Purchase Behavior When a user completes an upsell: * A new one-time purchase or subscription is created * The product is added to the existing Stripe customer * The original purchase remains unchanged This makes upselling seamless for the user while keeping billing clean and consistent in Stripe. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
