# 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 Subscription Upsells in Aftersell

Open the Aftersell app, go to the post-purchase upsell section, and create an upsell offer. Select a subscription product (linked to your Stay.ai selling plan) as the upsell item. The shopper can now subscribe right after checkout.

The connection between Aftersell and Stay.ai is enabled through Shopify's native Selling Plans, so make sure your selling plans are fully configured in Stay.ai before creating the upsell in Aftersell.
