Start in the aws console and click on Route53 under the Network & Content Delivery section:
You’ll see the Route53 Dashboard. Notice the Alerts for recent events (towards the bottom) and the Domain Registration (on the top right). Click on the Domain Registration.
This will take you to a list of all the domains. (Right now, they all fit on one page, this will change as domains come to AWS.) Notice the column for expiration dates:
If you’ve recently gotten a domain registration invoice and want to reconcile, click on Domain Billing Report. You’ll be prompted to pick a date range and csv file will download to your computer.
It’ll be something like this, with InvoiceId, Domain Name, Amount and Date.
