12 Best Shopify Checkout Upsell Apps (2026)

Checkout is one of the best opportunities to increase your Shopify store’s average order value because the customer has already decided to buy. A relevant upsell can help you add more to the order without requiring you to attract another customer.

With so many Shopify checkout upsell apps available, choosing the right one can be difficult. I tested many Shopify checkout upsell apps on my development store and narrowed them down to 12 of the best options.

In this guide, you’ll find a quick overview of each app, its key features, pricing, ratings, and what makes it a good fit for different types of Shopify stores. By the end, you’ll have a clearer idea of which Shopify checkout upsell app is right for your store.

How to Choose the Right Checkout Upsell App

Before comparing apps, first check whether your Shopify plan supports in-checkout upsells. This will help you narrow down which apps and upsell options are actually available for your store.

What to Look for in a Checkout Upsell App

Comparison Table - 12 Best Shopify Checkout Upsell Apps

Selleasy

Key Features

• Checkout upsell: Shows customers an extra product offer while they are checking out.
• AI recommendations: AI suggests relevant products to recommend, so merchants don't have to set up every recommendation manually.
• Matches the store design: The offer looks like part of the checkout page and matches the store's branding instead of appearing as a separate popup.
• Other upsell options: Selleasy also supports upsells on product pages, cart, and after purchase.

Strengths

• One app, one price: Checkout upsells are included in Selleasy, so merchants don't need to pay for a separate checkout upsell tool.
• Less manual work: AI helps choose relevant products to recommend, so merchants don't have to create rules for every product.

Limitations

• No checkout A/B testing: Merchants can't easily test different checkout offers to see which one performs better.
• Checkout isn't priced separately: Even though Selleasy's pricing is relatively affordable, merchants can't choose a cheaper checkout-only plan. The checkout upsell comes as part of the overall Selleasy plan.

Best suited for:

 Shopify Plus stores that want to add upsells at checkout without paying extra for a separate checkout upsell tool.‍

AfterSell

Key Features

• Reward bars: Shows messages such as rewards or incentives during checkout to encourage customers to complete their purchase. This also requires Shopify Plus.
• Testimonials/social proof: Shows customer reviews or testimonials during checkout to build trust and encourage the customer to buy.
• Included in the plan: These checkout features are included in the $34.99/month plan, so there is no separate fee for each feature.
• Other upsells: AfterSell also offers upsells after purchase and on the thank-you page, which work on regular Shopify plans.

Strengths

• Multiple checkout features in one plan: You get checkout upsells, reward bars, and testimonials without paying separately for each one.

Limitations

• Checkout A/B testing is unclear: AfterSell offers A/B testing and analytics, but it's not clear whether these features work specifically for checkout widgets. You should confirm this before relying on them.
  
  
• Requires Shopify Plus and a paid plan: You need Shopify Plus to use these checkout features, and you also need a paid plan. The free plan is only for development/partner stores, so you can't properly test these features on a live store for free.

Best suited for

Shopify Plus stores that want different types of checkout offers like product upsells, reward bars, and customer reviews all in one app and one plan. However, it's best to confirm with AfterSell whether A/B testing and personalization work specifically for checkout offers.

Candy Rack

Key Features

• Checkout upsells: Candy Rack lets you show additional product offers during checkout.
• AI recommendations: Candy Rack uses Google Gemini to automatically choose products to recommend. However, it is not clear whether this AI feature specifically works for checkout offers.
• Other upsells: It also supports upsells on product pages, in the cart, and after purchase.

Strengths

• No separate checkout fee: The checkout upsell is included in the same Candy Rack plan, so you don't have to pay extra just to use checkout upsells.

Limitations

• Checkout A/B testing is unclear: Candy Rack supports A/B testing through Intelligems, but it's not clear whether you can use it specifically for checkout offers.

Best Suited for

Stores that want checkout upsells included in the same plan, but are comfortable confirming the checkout-specific features before choosing the app.

ReConvert

Key Features

• One-click upsells: Customers can add the recommended product with a single click, including offers shown after checkout.
• AI recommendations: AI can suggest products that are relevant to the customer's purchase.
• Other upsells: Also supports upsells on product pages, cart, and after purchase.

Strengths

• Checkout is included in all plans: Checkout upsells are part of the main feature set rather than being locked behind an expensive higher plan.
• A/B testing and analytics: The app lists A/B testing, analytics, and customer segmentation along with its checkout features. However, it's still better to confirm that these specifically work with checkout offers.

Limitations

• Pricing can increase as your store grows: The price is based on either your monthly order volume or upsell revenue, whichever results in the higher charge. So your bill can increase as your store gets more orders or generates more upsell revenue.
• The free plan is only for development stores: You can't use the free plan to properly test checkout upsells on a live store.

Best Suited for

Stores that want checkout upsells along with AI recommendations, A/B testing, and analytics, and are comfortable with pricing that can increase as the store grows.

Upsell Plus Checkout

Key Features

• Checkout upsells: Lets Shopify Plus stores show extra product offers during checkout.
• Targeting based on cart: You can set offers to appear based on what the customer has in their cart. For example, if someone adds a dress, you can show them a matching bag at checkout.
• Multivariate A/B testing: Lets you test multiple versions of an offer at the same time to find what works best.
• Other upsells: Also supports upsells on product pages, cart, post-purchase, thank-you page, customer accounts, and Shopify POS.

Strengths

• Specific checkout targeting: You can create checkout offers based on the products in the customer's cart, rather than relying only on general personalization.
• Advanced testing: Multivariate A/B testing is available on plans that include checkout upsells, allowing merchants to test multiple factors instead of just comparing two offers.

Limitations

• Revenue limits: Each plan has a limit on how much upsell revenue you can generate. If you go over that limit, you need to move to a higher plan.
• AI is only on the higher plan: AI product recommendations start with the Shopify Plus plan, so lower-priced plans don't get AI-powered product suggestions.

Best Suited for

Shopify Plus stores that want detailed checkout targeting and advanced A/B testing, but are comfortable with the more complex pricing and plan limits.

C Builder (Checkout Builder)

Key Features

• Conditional offers: You can set rules for when an offer should appear. For example, “If the customer has a dress in their cart, show them matching shoes.”
• Trust badges and messages: You can add things like trust badges, reassurance messages, or other custom content to the checkout.
• Built with Shopify's newer technology: It uses Checkout Extensibility, Shopify's current method for customizing checkout. This is designed to work with future Shopify updates.
• Other features: It can also customize the Thank You and Order Status pages, including for some non-Plus stores.

Strengths

• Uses Shopify's latest checkout technology: Because it uses Checkout Extensibility, it's built to stay compatible with Shopify's future updates.
• More than just upsells: You can manage checkout upsells, trust badges, messages, and conditional offers from the same app.

Limitations

• Expensive: At $199/month, it is one of the more expensive options, especially compared with apps that include checkout upsells at a lower price.
• Shopify Plus is required: Checkout customization and checkout upsells are only available to Shopify Plus stores. Non-Plus stores don't get these checkout features.

Best Suited for

Shopify Plus stores that want checkout upsells along with more control over the checkout design and are willing to pay a higher price for it.

Honeycomb Upsell & Cross-sell

Key Features

• Offers upsells directly in checkout, but this feature is exclusive to Shopify Plus. It also supports upsells on product, cart, and thank-you pages.
• Includes A/B testing so you can compare different upsell offers. However, it’s not clear whether this testing is available specifically for checkout upsells or only for the other funnel placements.
• Supports one-click post-purchase upsells and automatically combines the additional purchase with the original order.
• Product page, cart page, and thank-you page upsells are available on all Shopify plans. This review focuses specifically on the checkout feature.

Strengths

• Checkout upsells are available even on the free plan, which is a benefit compared with competitors that require a paid plan for checkout upsells.

• The developer, Conversion Bear, appears to actively respond to negative reviews and follow up on serious issues.

Limitations

• Pricing is based on monthly funnel views rather than orders or revenue. Stores with lots of traffic may reach their view limit quickly, even if they don't generate many orders.
• It's unclear whether the A/B testing feature works specifically for checkout upsells or only for product, cart, and thank-you page funnels. If checkout testing is important to you, it's worth confirming this before choosing the app.

Best Suited for 

Shopify Plus stores that want checkout upsells without paying for a separate paid plan. It may be a good fit for smaller stores with lower traffic, since the pricing is based on funnel views. However, it’s worth checking recent reviews before choosing it, as some merchants have reported support and technical issues.

Sellmore

Key Features

• Available in all plans: Checkout upsells are included in the feature set from the free plan onward, although the free plan is only for development/partner stores.
• AI recommendations: AI can suggest relevant products to customers based on their purchase.
• Other upsells: Also supports upsells on the post-purchase page, thank-you page, and order status page.

Strengths

• Checkout upsells are included from the start: You don't need to upgrade to a higher-priced plan just to get checkout upsells.
• Analytics are included: Analytics are available in every plan, so merchants can track how their upsells are performing.

Limitations

Price increases with store orders: The price is based on the store's total monthly orders, not just the orders where a checkout upsell is shown. So the cost increases as the store gets more orders.

Best Suited for

Shopify Plus stores that want checkout upsells, AI recommendations, and analytics at a relatively low price, but are comfortable choosing a newer app with limited customer feedback.

Zipify OneClickUpsell (OCU)

Key Features

• AI-powered upsells: AI automatically chooses and improves product recommendations based on the store's data.
• A/B testing: Lets you test different offers to find out which one works better.

Strengths

• Strong Shopify Plus credentials: Zipify is officially a Shopify Plus Certified Technology Partner, specifically highlighting its native checkout upsells.
• Checkout included from the starting plan: Checkout upsells are included in the $8/month starting plan, rather than requiring a separate expensive checkout plan.

Limitations

• $8/month is only the starting price: The cost increases as the app generates more upsell revenue, so the actual amount you pay can be higher.
• Checkout-specific AI and A/B testing are unclear: The app offers AI and A/B testing, but its listing doesn't clearly show whether these features specifically apply to checkout offers. It's better to confirm this if checkout testing is important to you.

Best Suited for

Shopify Plus stores looking for a relatively low starting price, native checkout upsells, and AI-powered upselling, but that are comfortable with pricing that increases as upsell revenue grows.

• Built-in A/B testing: You can test checkout offers directly in the app instead of connecting another tool.

Limitations

• More expensive for checkout upsells: You need the $99/month plan to use checkout upsells, which is more expensive than several competitors.

Best Suited for

Shopify Plus stores that want built-in A/B testing and several types of checkout offers and are willing to pay $99/month for these features.

• Good support: Customers mention quick and hands-on support.

Limitations

• No A/B testing mentioned: The app doesn't appear to offer built-in A/B testing, so you can't easily compare different checkout offers within the app.

Best Suited for

Shopify Plus stores that want targeted checkout upsells and easy checkout customization, especially if responsive support is important to them.

OrderBump

Key Features

• Different pricing for checkout: The $39/month Standard plan includes post-purchase upsells, but checkout upsells require the $139/month Shopify Plus plan.
• AI offer matching: AI helps decide which upsell to show to each customer.

Strengths

• Focused on upselling: The app mainly focuses on checkout, cart, and post-purchase upsells rather than trying to provide many unrelated features.

Limitations

• Expensive for checkout: At $139/month, checkout upsells are relatively expensive compared with several competitors. There's also a big jump from the $39 Standard plan.
• No A/B testing: The app doesn't list a built-in A/B testing feature, so you can't easily test different checkout offers to see which performs better.

Best Suited for

Shopify Plus stores that mainly want checkout and post-purchase upsells and are willing to pay a higher price for a focused upselling tool.

Which Shopify Checkout Upsell App Is Right for Your Store?

The best app depends on what is most important to you—price, A/B testing, targeting, different types of checkout offers. Here's a simple comparison:

The Bottom Line

Checkout upsells can be a great way to increase the value of each order, but you need Shopify Plus to show an upsell directly during checkout. So, the first thing to check is whether your store has Shopify Plus.

After that, compare the apps based on pricing, A/B testing, targeting options, and extra features. Some apps offer a fixed monthly price, while others charge based on orders or upsell revenue. Some also offer features like trust badges, reward bars, and upsells on product and thank-you pages.

The best approach is to try a few apps on your store first. This helps you see which one is easiest to set up, works well with your store, and gives you the results you need before paying for a plan.

FAQs

1. Do I need Shopify Plus to use checkout upsell apps?

Yes, for true in-checkout upsells — offers shown directly during checkout, before payment, require Shopify Plus and Checkout Extensibility. This applies to every app in this list. 

2. How to upsell at checkout in Shopify?

If you're on Shopify Plus, you can add upsell offers directly in the checkout using Shopify extensions or apps like Selleasy, Candyrack or any of the above apps. 

For non-Plus users, use cart page, post-purchase, or thank-you page upsells.

3. What if I'm not on Shopify Plus, can I still run checkout-style upsells?

Yes. Most apps on this list also offer post-purchase, thank-you-page, or order-status upsells that work on any Shopify plan, even though the checkout-specific placement itself requires Plus. 

4. What is the best checkout upsell app for Shopify?

Candy Rack, Selleasy, Upsellplus checkout plus and all the other above-mentioned apps have been tried and tested individually in my dev store. Be mindful of how to choose the best app by analyzing your store’s needs.  

5. How to upsell in Shopify checkout without an app?

Upselling has certain limits when you want to do it in your checkout page without an app. Usually, it is done by playing around with the shipping charges and methods. 

However, using an app gives you more flexibility to add any upsell products of your choice, with so many other benefits that come with the app.
