Viewing your pro forma data in AWS Budgets
AWS accounts in AWS Billing Conductor billing groups can monitor pro forma spendings using AWS Budgets. Budgets created by AWS accounts in Billing Conductor billing groups capture the pro forma billing data, enabling alerts when your pro forma spending limit is exceeding. The budget forecast will also be based on the pro forma data, and you will be alerted when you are about to exceed your spending limit as well.
Billing group primary accounts can monitor the holistic billing group pro forma spend, and spending on specific billing group member accounts. Billing group managed accounts, or billing group members, can create and view pro forma budgets of their own AWS accounts. These accounts can see the budget history for the billing periods they were members of the billing group. Billing data isn't shared from the budget history for dates prior to joining the billing group.
When accounts join a billing group, their existing budget information will begin capturing pro forma data. The budget history and forecast are based on the pro forma data. When accounts leave a billing group, the budget begins capturing billable data. The budget history and forecast will be based on billable data going forward.
Note
We recommend linked accounts in billing groups, that previously had budget alerts configured on billable data, to update the threshold to the budget alerts to match the pro forma data view.
