How Shopify Merchants Can Boost Revenue with Checkout Plus

As Shopify continues evolving its platform, Shopify Checkout UI Extensions have become one of the most powerful tools available for merchants looking to customize checkout, increase conversions, and grow revenue.

For Shopify merchants, especially Shopify Plus brands, understanding Checkout UI Extensions is essential—not only to stay competitive, but to unlock advanced revenue-driving opportunities through apps like Checkout Plus.

If you want to improve average order value (AOV), personalize your checkout, and future-proof your store, Checkout UI Extensions are the foundation.

Section 1: What Are Shopify Checkout UI Extensions?

Shopify Checkout UI Extensions are Shopify’s modern framework that allows merchants to safely customize the checkout experience using app-powered features instead of outdated custom code.

Rather than relying on deprecated tools like Shopify Scripts or checkout.liquid, merchants can now use approved apps like Checkout Plus to add powerful checkout enhancements directly into Shopify’s secure checkout environment.

With Shopify Checkout UI Extensions and Checkout Plus, merchants can add:

• Checkout upsells and recommended products
• Trust badges and testimonials

• Surveys and custom form fields
• Localization and translation support
• Branding controls
• Post-purchase upsells

For merchants, this means safer, easier, and more profitable checkout optimization.
