It would probably be best to ask Oculus. This is a community forum.
If you are buying them for a company event, that sounds like a commercial use so you should go through the Business program. They can probably handle bulk orders better, since consumers trying to buy more than a couple of Quests is liable to be considered a scalper and the order would be refused.
Oh god, imagine how long it would take to set up 550 Quest 2's! Watching the unskippable safety videos, logging them all into facebook, etc.
That's the other benefit of the Business license, you can control what people can do on them and don't need facebook.
