Determine Office 2013 POSA and Product Keys

Any reseller familiar with Office 2013 will understand what a total disaster it is activating. If you answer isn't relevant to Office 2013 please don't answer.

   Keeping track of multiple product keys under one account is difficult at best especially if you activated before they showed the product key of the one you were trying to install.
1) Is there a program or a web site that will tell you what account your POSA key is registered to?
2) Is there a program that you can run on the computer to show you the Office 2013 Product Key?

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Showing the key might be extracted with:
Belarc (free private use)

As far as software tracking I have used a spreadsheet, discovery (extract keys), and also a Microsoft Volume Lic. web portal.  If you buy the software from a vendor they might be registering the information with Microsoft.  I have not bought the subscription (other than Office 365), or card based versions.  

It does get complicated if you work with licensing that cannot be moved to another pc.
