Understanding the AWS Billing Conductor Service better

0

After setting up the "AWS Billing Conductor Service" for custom pricing I am confused about the general setup and might be missing the right hint / documentation. Kindly requesting your support in understanding this service better.

  1. I understood a new linked AWS Account is required during setup and must not be the Management Account: What activities are usually performed in “Designated Billing Conductor Account”, what in “Management Account" (root)? Any documentation on this?

  2. More general: What is the purpose of a separate account for "AWS Billing Conductor"?

  • I have set up the "AWS Billing Conductor" service. Logging into the "Designated Billing Conductor Account" and visiting the Dashboard of the "AWS Billing Conductor" service shows: "You are not authorized to perform this action. Note that this service is managed at the payer account level."
  • It seems the "AWS Billing Conductor" service itself is still managed in the Management Account (root). I do not get why I must select a linked account other than the Management Account.
  1. Does the "AWS Cost and Usage Report" & "AWS Cost Explorer" in the Management Account (root) show the custom pricing or the "real / unmodified" pricing?
  • Kindly requesting support on below:

    Item 2 from the "Bot Answer" seems incorrect.

    During Set up of the "Billing Group" of "AWS Billing Conductor" service, I am required to choose a "Primary Account". The Management Account (Root) cannot be selected as a Primary Account for the Billing Group. Therefore I must select an account different from the Management Account (Root) -> new or existing linked account is required.

    Therefore the question: What is the purpose of a separate account for "AWS Billing Conductor" especially when you say "everything" is managed in the Management Account.

    Is there an overview of actions with Management account and "Primary Account for Billing Conductor"?

I apologize, but there seems to be some confusion in your understanding of AWS Billing Conductor. Let me clarify based on the information available:

  1. AWS Billing Conductor does not require a new linked AWS account. It is managed at the payer or management account level. There is no "Designated Billing Conductor Account" separate from the management account. All activities related to AWS Billing Conductor, such as creating billing groups, pricing plans, and viewing custom rates, are performed in the management (payer) account.

  2. There is no separate account for AWS Billing Conductor. The service is accessed and managed through the payer or management account. The error message you're seeing suggests that you're trying to access the service from a linked account rather than the management account. AWS Billing Conductor is only accessible to users who have access to the payer or management account.

  3. The AWS Cost and Usage Report (CUR) and AWS Cost Explorer in the management account will show both the actual AWS billing data and the pro forma costs created by AWS Billing Conductor. The pro forma costs represent the usage within Billing Conductor managed accounts at the pricing rates defined within the service. These pro forma costs do not change your actual AWS invoice but provide a customized view of costs based on your configured pricing plans and rules.

To use AWS Billing Conductor correctly:

  • Log in to your management (payer) account
  • Ensure you have the necessary IAM permissions to access and manage Billing Conductor
  • Create billing groups to organize your accounts
  • Set up pricing plans and rules as needed
  • View the custom rates and pro forma costs in the Billing console or through generated Cost and Usage Reports for each billing group

Remember, AWS Billing Conductor is designed to create a second, customized version of your costs without affecting your actual AWS billing. It's primarily used for chargeback scenarios or to align costs with specific business requirements.
