AWS Billing and Cost Management
User Guide (Version 2.0)

Billing and Account Activity

Each month, AWS charges the master account owner, and not the owners of the member accounts. To see the total usage and charges across all the accounts in an organization, see the Bills page of the master account. AWS updates the page multiple times each day. Additionally, AWS makes a downloadable cost report available each day.

Although the owners of the member accounts aren't charged, they can still see their usage and charges by going to their AWS Bills pages. They can't view or obtain data for the master account or any other member accounts on the bill.
