The blog reviews the 7 leading Shopify checkout upsell apps, including Checkout Wiz, Upsell Plus, Zipify One Click Upsell, Checkout Buddy, Monk Free Gift, One Click Checkout Upsell, and CartHook Post-Purchase Upsell.
Shopify checkout upsell apps are used to show product recommendations, cross-sells, upsells, line-item upgrades, and line-item volume-based upsells during checkout or immediately after purchase, when buyer intent is highest.
Shopify does not support in-checkout upsells on standard Shopify plans. The ability to modify checkout requires Shopify Plus and the use of Checkout Extensibility through a dedicated Shopify checkout app.
The Shopify checkout apps were evaluated based on checkout upsell types, rule depth and targeting, support for free gifts, support for line-item upsells, analytics, A/B testing, pricing structure, and merchant reviews.
The guide concludes that Checkout Wiz is the most well-rounded option overall because it supports multiple checkout upsell formats and includes native A/B testing alongside broader checkout customization.
Introduction
Shopify checkout upsell apps are used by stores to increase their average order value by showing relevant add-ons, upgrades, or recommendations within the checkout. This guide helps you uncover the best checkout upsell apps based on their upsell capabilities, widget design, placement at checkout, reviews, pricing, analytics & more.
Remember, Shopify does not allow merchants to add upsells at checkout on standard plans. Checkout modifications & upsells are available only in Shopify Plus stores. But to make such changes, a store needs a checkout upsell app. Hence, I’ve written this comparative guide, which will help you pick the best. Let's dive in.

Why Do You Need a Shopify Checkout Upsell App?
Shopify’s primary limitation for checkout upsells is that true checkout customization is only available on Shopify Plus. Only Shopify Plus stores can access Shopify’s Checkout UI Extensions and make changes to their Shopify checkout.
Checkout extensibility allows merchants to introduce elements such as:
In-checkout upsell blocks
Trust badges and assurance messaging
Free-shipping progress bars
Reviews and ratings
Custom fields and validations
However, Shopify does not provide native tools to build these experiences out of the box. Merchants must either develop a custom checkout app or rely on dedicated Shopify checkout upsell apps built on checkout extensibility.
As a result, implementing checkout upsells on Shopify requires both the Shopify Plus plan and a specialized checkout upsell app, making third-party solutions essential for merchants who want to optimize checkout performance and increase AOV.

In this guide, we examined leading Shopify checkout upsell apps such as Checkout Wiz, Aftersell, Zipify, UpsellPlus, Checkout Buddy, Monk & Checkout Plus. We evaluated them on upsell formats, targeting rules, line-item upgrades, analytics, AB testing, pricing, and reviews.
