AWS Cost Explorer preserves billing history for accounts
📊 AWS announces Cost Explorer historical data retention for accounts in billing groups. Customers using AWS Billing Conductor and Billing Transfer can map accounts to billing groups and view billing data priced at the payer or Bill-Transfer account's pro forma rates. Previously, billing group mapping restricted access to historical billing data priced at AWS billable rates. Accounts already onboarded will retain access to their historical Cost Explorer data with no additional action required.
