Shopify Checkout UI Extensions

Take full control of your Shopify Plus checkout experience with modular, flexible, and secure UI extensions.

Shopify Checkout UI Extensions allow store owners on Shopify Plus to modify the most crucial part of the sales funnel—checkout. Until recently, customizing checkout was either impossible or required risky workarounds. But now, Shopify has opened a secure, flexible gateway for developers to inject tailored elements into the native checkout experience.

Whether it’s adding upsells, customizing delivery messages, offering loyalty points, or changing payment logic, these extensions make it possible—without touching the core checkout code. Built directly on Shopify’s framework, Shopify Checkout UI Extensions are scalable, stable, and designed to work with checkout.liquid deprecation in mind.

At Kolachi Tech, we help brands design and deploy Shopify Checkout UI Extensions that enhance customer experience, increase average order value (AOV), and drive conversions.

Your checkout should work just as hard as the rest of your store. With our Shopify Checkout UI Extension services, we create impactful changes like:

• Trust badges and guarantee icons

• Custom delivery messaging

• Payment method highlighting

• Conditional fields and logic

• Loyalty integration displays

• Additional upsell options right before payment

All these changes are made without compromising performance, security, or compliance. And because extensions work with Shopify’s dynamic rendering system, your store stays lightning-fast.

Kolachi Tech has helped dozens of Shopify Plus brands take their checkout experience to the next level—and we’re just getting started.
