15 Best Checkout Extensibility Apps Shopify to Customize Checkout Experiences (2024)

The checkout process of your Shopify store can make or break your sale - and the value of it too. If the checkout procedure is excessively difficult or lengthy, 60% of customers are likely to leave their cart. This means you are losing more than half of your sales due to unoptimized checkout experiences. 

And if you’re not using the shopping-ready psychology of the buyer during checkout to its full advantage, you’re losing an opportunity to upsell and cross-sell. 

That’s why it’s important for brands to focus on customizing their checkout process - not just to reduce the friction to buy and reduce cart abandonment, but to also tap into the opportunity to sell more. 

While Shopify has recently launched Checkout UI Extensions to enable this customization, the capability is reserved only for Shopify plus merchants. In fact, there are several Shopify checkout apps being developed using this new technology for Plus merchants. 

So is Shopify checkout customization only possible for Plus stores? 

Well, the answer is no. 

In this post, we’re going to list out Shopify checkout apps that use Checkout Extensibility for Plus merchants, but some that also enable customization to other stores.
