Billing and Account Activity
Consolidated billing is now a feature of AWS Organizations. The information provided in the Billing and Cost Management documentation might be out of date. For current information about consolidated billing, see Consolidated Billing and AWS Organizations in the AWS Organizations User Guide.
Each month, AWS charges the payer account owner, and not the owners of the linked accounts. The paying account's AWS Bills page shows the total usage and charges across all the accounts on the bill. That page is updated multiple times each day. Each day, AWS makes a downloadable cost report available.
Although the owners of the linked 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 paying account or any other linked accounts on the bill.
