Shopify Checkout Extensions Explained

Checkout extensions are Shopify's modern way to customise checkout without editing checkout.liquid. They let you add UI elements — banners, custom fields, upsells — and logic at specific points in the checkout, running safely in Shopify's environment. They are the recommended path now that checkout.liquid is being deprecated.

Extensions keep your checkout fast, secure and upgrade-safe. Experts Cabin develops checkout extensions for Shopify Plus brands that want a branded, higher-converting checkout.
