AWS – Setting up consolidated billing

How to create virtual machines with VirtualBox

By setting up your accounts with AWS Organizations, you can consolidate your AWS bill so that you are not being charged separately for each of your child accounts. You get one bill for all the accounts and you can easily track the charges from a single place. By combining accounts, you will save money by sharing volume discounts and reserved instance pricing.

How to do it…

All you have to do to enable consolidated billing is create a master account in AWS Organizations (or via Control Tower, as described earlier in this chapter). The master account will be automatically configured to receive the bill for all subordinate accounts. For billing purposes, all accounts will be treated as one account, so you can maximize savings from any volume discount that you might have. Reserved instance pricing will aggregate your EC2 instances across accounts.

How it works…

The master account in an organization is responsible for paying the bill for all its accounts in the organization. If you are an administrator of the organization, you can see a consolidated billing report and view charges for each individual account. A separate bill is generated for each account, but it is for information purposes only. The only bill that needs to be paid is the bill that is associated with the master account.

Estimated charges are calculated several times per day, so that you can always get an idea of what your total monthly bill will be.

There’s more…

The following are a few more things related to consolidated billing that you might want to keep in mind.

  • Credits
  • Support charges

Credits

If you have any AWS credits applied to any of your accounts, the credits will also apply to your organization as a whole.

See the AWS documentation to find out exactly how credits are applied: https://docs.aws.amazon.com/awsaccountbilling/latest/aboutv2/useconsolidatedbilling-credits.html.

Support charges

Support contracts are still applied to each account individually. It is a highly recommended best practice to have, at a minimum, business support enabled on all production accounts. Each account in your organization needs to subscribe to the support agreement separately. The exception is an enterprise support contract, which can cover all of the accounts in your organization.
