Checkout is a single page with every section on it: contact, delivery, shipping and payment. The order summary sits beside the form on wide screens and opens from a Show order summary bar on phones.
Contact comes first
The shopper first enters an email address or phone number. When customer accounts are Required, they confirm it with a one-time code. When accounts are Optional, they can continue as a guest or sign in with a code. Choose the mode in Customers > Settings > Accounts.
Delivery, shipping and payment are visible below Contact but stay locked until contact is complete, then open in place without leaving the page.
Preview and text
The editor preview shows your draft with sample scenarios. Edit checkout text covers every message on the page, including Show order summary, Hide order summary and the messages on locked sections.
