10 Best Shopify Checkout Apps You Need to Know in 2026

How often have you had customers add your products to their cart and then suddenly abandon them at checkout?

It does happen more often than you think. Baymard Institute puts the average documented cart abandonment rate at 70.22%. This means only 3 out of 10 online customers complete their checkout and place the order. Cart abandonment translates to lost sales and missed opportunities for your business.

Many reasons have led to this, and one of the popular solutions is to improve your checkout experience using Shopify checkout apps. A smooth and optimized checkout process can significantly reduce cart abandonment rates, boost conversions, and increase your average order value. In this article, we review ten of the best Shopify checkout apps in 2026, with ratings, plan requirements and pricing checked on the Shopify App Store.

Updated October 21, 2026: ratings, review counts, plan requirements and prices for all ten apps were re-checked on the Shopify App Store. SweetCheckout is no longer listed, so it was replaced with Checkout Blocks by Shopify; two apps have new names.

Why Do You Need to Customize Shopify Checkout Apps?

While Shopify offers a basic checkout experience, it might not be enough to maximize your sales potential or reduce cart abandonment. The default checkout can feel limited, often lacking:

• Customization features that allow you to add fields to your specific needs or add unique branding elements.
• Limited upselling or cross-selling opportunities to promote complementary products or highlight special offers at checkout.
• The standard checkout may not be optimized for mobile devices.

By customizing your checkout with Shopify apps, you are able to:

• Streamline the checkout process with custom layouts and pre-filled fields, leading to quicker customer purchases.
• Upsell and create targeted promotions at checkout to encourage customers to spend more.
• Create strategic offers for customers to incentivize, nudging them to add more items to their cart and boosting your AOV.
• Create a quick and faster checkout process with one-click checkout options.

With mobile cart abandonment rates being the highest, creating a standout mobile checkout interface and experience is important. Customizing your overall purchase experience using Shopify apps will help you optimize even your mobile checkout page, ensuring a smooth and intuitive shopping experience.

What is Shopify Checkout Extensibility?

Checkout Extensibility is Shopify's app-based, upgrade-safe way to customize checkout without editing code. Checkout apps plug into it, and what they can change depends on your plan: apps that customize the Thank you and Order status pages are available on the Basic Shopify plan and higher, while apps that customize the information, shipping and payment steps are available only on Shopify Plus (source: Shopify Help Center).

With Checkout Extensibility, you can:

• Select from a variety of pre-built apps on the Shopify App Store to add features, personalize your checkout, and ensure a secure, upgrade-safe experience.
• Developers can leverage APIs and components to build custom apps for highly unique needs, offering maximum flexibility.
• Integrate with Shop Pay, a fast and secure checkout option known to boost conversion rates.

Having Shopify Checkout Extensibility and checkout UI extensions helps create a faster checkout, which Shopify says results in up to 1% higher conversion on average (source: Shopify Partners blog).
