# Aftersell & Stay.Ai Integration

> This article explains how to set up the Aftersell and Stay.ai integration.

**Stay AI** is a powerful subscription management platform built to help e-commerce brands drive retention and boost customer lifetime value. One of its standout features is the ability to create flexible, data-driven selling plans that adapt to customer behavior. Stay AI integrates seamlessly with **Aftersell**, allowing you to offer post-purchase subscription upsells and further maximize the value of each customer.

***

To enable subscription-based upsells using **Stay.ai** and **Aftersell**, follow the steps below:

## 1. Install the Apps

* Download both the **[Stay.ai](https://apps.shopify.com/stay-ai)** [app](https://apps.shopify.com/stay-ai) and the **[Aftersell](https://apps.shopify.com/aftersell)** [app](https://apps.shopify.com/aftersell) from the Shopify App Store.

## 2. Set Up Selling Plans in Stay.ai

* In the **Stay.ai** dashboard, navigate to **Subscription Setup > Selling Plans**.
* Create your **Selling Plans** and organize them into **Selling Plan Groups**

  * These plans define your subscription options and are required for Aftersell to recognize your subscription products.

## 3. Configure Upsells in Aftersell

* Open the **Aftersell** app and go to the **post-purchase upsell** section.
* Create an upsell offer and select a **subscription product** (linked to your Stay.ai selling plan) as the upsell item.

  * This allows you to offer subscriptions right after checkout.

**Note:** The connection between Aftersell and Stay.ai is enabled via **[Shopify’s native Selling Plans](https://shopify.dev/docs/apps/build/purchase-options/subscriptions/selling-plans)**. For the integration to work, make sure your selling plans are fully configured in Stay.ai **before** creating the upsell in Aftersell.
