# Bill to AWS for re:Invent
<a name="what-is-eventsbilltoaws"></a>

 "Bill to AWS" allows attendees to bill re:Invent pass purchases directly to their AWS account. An AWS account administrator must authorize the billing by attaching the `ReInventTicketApprovalAccess` managed policy to the approver's IAM identity. 

## How the Bill to AWS payment flow works
<a name="how-bill-to-aws-works"></a>

1. An attendee registers for re:Invent and selects "Bill to AWS" as payment method.

1. An attendee provides their organization's AWS Account ID and Approver email.

1. The approver receives an email with a link to the AWS Management Console.

1. The approver signs in to the AWS Management Console and reviews the charge details.

1. The approver approves or declines the charge.

1. If approved, the ticket charge appears on the AWS account bill.

**Note**  
 The approver has 7 days to act on the request. If no action is taken, the request expires and the attendee must resubmit.
