UX for checkout
Checkout is the most critical step of the customer journey. Checkout should help customers feel in control and confident about their purchases. Use our UX guidelines when you're designing your checkout experiences to ensure that they're trustworthy, efficient, and considerate.
Anchor to Maintain trustMaintain trust
Customers should understand why they need to input personal information, and what will happen when they take an action. This builds trust between a customer and the merchant.
Example: Make it clear if an item costs money. Customers could miss this information if it's hidden among other content.

Example: When checking out requires the customer to supply personal information, let them know why.

Anchor to Reduce frictionReduce friction
Friction in checkout can have an impact on checkout conversion. To reduce friction, localize your experiences, write effective content, and only show components when you know that customers need them.
Localization is only supported for checkout UI extensions. Localization for post-purchase extensions isn't supported. Shopify Functions also have support for localization.
Example: Show options when you know that customers need them.
Example: Help customers understand what's optional.

Anchor to Test different scenariosTest different scenarios
Although you might use a desktop while developing, the majority of customers make purchases on mobile devices. Many customers also use accelerated checkout options, like Shop Pay, which pre-fill the checkout with vaulted information. Test your extension to ensure that it behaves as desired in these scenarios.
The following are some examples that you can test for:
-
Mobile and desktop
-
Guest checkout and Shop Pay
-
Physical, digital, and discounted products
-
Ship and pickup delivery methods
Example: Checkout UI extension targets might change location between guest checkout and Shop Pay.
