Accordion-style checkout processes are becoming more and more popular, for good reason:

• They allow a lot of fields to be organized and therefore processed easily.
• A checkout process is a commitment, so the easier it is the better.

Accordion-style checkouts are a take on an organized and dynamic linear checkout process, but the fields and data, and content is chunked into manageable parts all without any page load if implemented well with AJAX.

There are two important things to keep in mind when using them:

1. Don’t completely hide info in the higher levels, provide summaries.
2. Make it apparent that the user is still on the same page and if they want to edit previous sections they’ll select an Edit button instead of the Back button.
