Will Checkout Plus Slow Down My Store?

Learn how Checkout Plus works with Shopify and whether it affects your store’s speed or performance.

Checkout Plus is designed to add powerful checkout customizations without slowing down your storefront.

Does Checkout Plus affect my storefront speed?

Checkout Plus primarily works within Shopify’s checkout and post-purchase experience rather than loading customizations throughout your storefront.

This means customers browsing your homepage, collections, and product pages aren’t loading Checkout Plus checkout customizations on every page.

What about checkout performance?

Checkout Plus uses Shopify’s supported checkout extensibility framework to provide customizations within the checkout experience.

Instead of replacing or modifying Shopify’s checkout, Checkout Plus works within Shopify’s supported systems to add features such as:

  • Checkout customizations

  • Upsells

  • Custom fields and checkboxes

  • Payment customizations

  • Shipping & delivery customizations

  • Order validations

  • Post-purchase offers

  • Thank You and Order Status page customizations

Shopify continues to handle the core checkout experience and transaction.

Does Checkout Plus modify my Shopify theme?

Checkout Plus checkout features do not require you to modify your Shopify theme code.

Because these features are built for Shopify’s checkout and post-purchase experiences, they don’t require adding large amounts of custom checkout code to your storefront theme.

What if I’m experiencing a performance issue?

Store performance can be affected by many factors, including your theme, images, third-party apps, tracking scripts, and other customizations.
