Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
No offense - but there are limitations to non-MS products and sometimes it is your customers who dictate the MS dependency. I use Libre Office for personal needs but is not completely compatible. You can make choices but often they are dictated to you.
I am with everyone else posting here. There is no such thing as an o365 device license and that is a real issue. There are things like Device CALs for Windows Server and Exchange that are device dependent but nothing office.
I work for a mid sized manufacturer. Virtually everyone touches office today and we are looking to make updates. The problem comes in with our Shop computers. 10 or so people may touch them but they don't have emails and all use Access, Excel and Word. Sure a viewer works here for Excel and Word BUT then you can not edit the documents. (And sometimes a user does use them to access their email with Outlook.) That's about 80 people who don't need a dedicated license for themselves but a device CAL works perfectly.
It's bad enough we have to buy Server CALs for them. But to have to spend $110 each or ~$9000 a YEAR to have them minimally use Office (but for critical needs) does not work. It is wasteful and simply a money grab.
We are certainly looking into Libre Office more closely for these users at least. The learning curve is not pretty for our user base though.
