The way where I work works (technically enterprise, a couple thousand full-time employees), if you want some software and think it's reasonably-priced, you can buy it and expense it. I've never heard of anyone getting in any trouble over this. You can also submit a helpdesk ticket to have purchasing buy something for you, which is what we'd do for e.g. Subscription licenses which require someone entering a corporate card and keeping track of it.
