Cost may not be an obstacle, but process is. For some companies, getting approval to do that won't be easy. When services have free tiers, people can try them out as individuals before they go on to champion the case for using that tool at work.

A free trial can also work here, but the really short ones don't work well. It's not reasonable to expect people to devote all their attention to evaluating your service. It may take a few weeks or even a month to rack up just a couple hours of trying something out.
