# Upgrade to Checkout Extensibility: Your Guide to a Smooth Transition

For me who [used to work on Shopify projects](https://testandoptimize.com/shopify-project-i-work-on), this is the big deal not just for Shopify Plus plan merchant. Besides the news about WPP (the largest advertising agency with a revenue of $17.85 billion) and Shopify in strategic partnership.

In June 2022, Shopify introduced checkout extensibility for in-checkout pages, which offers a better way to customize the Shopify Checkout that’s app-based, upgrade-safe, and more performant than checkout.liquid.

Checkout extensibility is a powerful new tool that can help merchants improve their checkout and increase conversions.

Benefits of checkout extensibility:

* Increased flexibility: Merchants will have more control over the look and feel of their checkout.
    
* Improved performance: This extensibility is designed to improve the performance of the checkout.
    
* Enhanced security: security features that help protect merchants from fraud.
    
* Reduced costs: With a built-in editor, merchants can save money on development costs.
    

To upgrade to checkout extensibility, merchants need to replicate any required checkout.liquid customizations in checkout extensibility using the platform features and developer tools.
