Hi
I highly recommend Not to use the forum for LICENSE questions. It might look like we understand since we orders several dozens licenses ourselves, but I learned that this subject can be very complex and you better read the small letters and understand it 100% before you recommend someone. There might be differences in locations, versions, editions, Machine resources, Various programs for partners, and much more. These are matters of law, not just technical data, and I recommend to ask Microsoft license department directly.

You should download the licensing data sheet and licensing guide for the version you want to use.
