Customize Checkout

Magento checkout is implemented using the UI components. Out of the box, the checkout consists of two steps:

• Shipping Information
• Review and Payment Information

The checkout totals and the corresponding side-bar are only displayed after the first step is completed.

The only exception is checkout of virtual and/or downloadable products: if there are only these types of products in the shopping cart, checkout is automatically transformed to one-step procedure, because shipping information is not required.

For the sake of compatibility, upgradability, and easy maintenance, do not edit the default Magento code. Add your customizations in a custom module.
