My Accounting Department requires some additional information on invoices. How can I obtain/ view a detailed breakdown of my invoices?

To view a detailed breakdown of your monthly invoice, you can do so by logging-in at https://cloud.engineyard.com/ (with the Account Owner email) and select from the menu: "Account" —> "Account Settings"

And then "Current Monthly Usage or Past Invoices"

Also, the invoices can be downloaded as .pdf by clicking on the relevant link:
