Updated October 2026: prices and features checked against the Shopify App Store.
As a store owner, you want buying from you to feel quick and easy. The checkout is where that matters most: every extra step or confusing page is a chance for a shopper to leave. Shopify checkout apps help you shorten the path to payment, add useful content to your checkout and thank-you pages, and earn more from each order. In this guide, we look at 9 popular Shopify checkout apps worth trying.
Why use a Shopify checkout app?
The main reason is to make buying faster. Shopify's own checkout is already quick and secure, but many shoppers still drop off on the way there. Checkout apps can add a "Buy Now" button, skip the cart page or send shoppers straight to checkout from any page. Fewer steps usually means fewer abandoned carts and more sales.
Secondly, some apps let you customise what shoppers see during and after checkout. Since Shopify retired checkout.liquid, these customisations are made with apps built on checkout extensibility. Every store can add content to the thank-you and order status pages, while changes inside the checkout steps themselves are mostly limited to Shopify Plus.
Finally, checkout apps can raise your average order value. Many of them show upsells in the cart, at checkout or straight after payment, so customers can add one more item without re-entering their details.
9 Best Shopify Checkout Apps for your store
