Products
The Products page is actually very similar to the Licenses page, but much more user-friendly and attractive. It displays the products your company is subscribed to, with icons showing what applications those products entitle you to. (Sometimes, the same application has multiple licensed products that can apply to it; for example, Audio Conferencing and Domestic Calling Plan both apply to Skype for Business. And many products offer multiple applications within; any Office plan that includes software will include Word, Excel, PowerPoint, and Outlook, for example.):
The Products page
As with the Licenses page, it'll show you how many licenses you have, how many are free to be used, and what their status is, and will give you the opportunity to assign licenses if some are free, or buy more if none are. Disabled and deprovisioned products won't show in this view. Note that Buy more just takes you to the Subscriptions page and Assign licenses takes you to Active users.
