How do I consolidate billing emails for my Organization's accounts?

If you have individual accounts purchasing items like Market Place subscriptions, these will be individual invoices as they are subscribed from those accounts, but they should be invoices at the payer level in an Organization. You should only get one single invoices for your AWS Services charges though to your AWS Organizations main payer account.

Are you seeing something different than this? If you have Enterprise Support I would suggest reaching out to your AWS Technical Account Manager for assistance.

Make sure you have set up the right tax settings for each of your accounts: https://aws.amazon.com/premiumsupport/knowledge-center/update-tax-registration-number/

You can update this information for all accounts from the Management Payer's console.

Check out another answer from Rob_H, as what they said might be one reason. But also, if you have many linked accounts that are set up with different tax/legal address and different seller of reccord in the tax settings, then you will be getting multiple invoices for each of the coutry / seller of record. If you'd like to streamline this process and you want all accounts be registered with the same tax/legal addres, you can update it in the Tax Settings.

For more information about this topic, I suggest you could contact AWS Support (Account & Billing), because the setup you have with your accounts may be different from other customers and this needs to be reviewed on case-by-case basis.

Also, note, if you are purchasing Reserved Instances or Savings Plans with All Upfront or Partial Upfront payment option from invididual linked accounts, then you will typically be receiving these invoices at the time of purchase, as this is a one time subscription charge (similar to Marketplace purchases).

One reason is if you received a PDF invoice by email and your alternate filling contact is the same email then you will receive two emails per account - (see: Billing - When your monthly invoice is available, or your payment method needs to be updated. If your Receive PDF Invoice By Email is turned on in your Billing preferences, your alternate billing contact will receive the PDF invoices as well. See: https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/manage-account-payment.html#manage-account-payment-change-currency ). Also, check the tax settings inheritance. Once activated then your usage from member accounts will consolidate to a single tax invoice. The steps are:

1. Sign in to the AWS Management Console and open the Billing and Cost Management console at https://console.aws.amazon.com/billing/
2. In the navigation pane, choose Tax Settings.
3. Under Manage Tax Registration Numbers, select Enable Tax Settings Inheritance.
4. Choose Continue. Finally, (I think this is known, but adding to levelset) the management account is billed for all charges of the member accounts. However, unless the organization is changed to support all features in the organization (not consolidated billing features only) and member accounts are explicitly restricted by policies, each member account is otherwise independent from the other member accounts. For example, the owner of a member account can sign up for AWS services, access resources, and use AWS Premium Support unless the management account restricts those actions. Each account owner continues to use their own IAM user name and password, with account permissions assigned independently of other accounts in the organization.
