In my humble opinion, as we can not really tell how they do it except we own and run our own businesses.  I would say that before companies decide to receive payment in bitcoin there are measure they must have put in place, given the fact that they know the volatile state of bitcoin, by this I mean they could consider converting BTC into stablecoins, or even hodl to earn more when pricing increases. The decision remains theirs to decide how it would benefit their companies.
