Yeah there was Jamf, but especially at a small company ~5-10-ish people, having to deal with a provider where you have to go through a sales person is such a pain. They have minimum license buys and deprio you if you're small... Now that it's natively supported just between Apple and MS, you can on-board yourself in about 1 day without talking to anyone, and the whole platform costs $0 if you have Office365 E3 already.
