People are usually unaware of their own incompetence (I don't mean the term harshly), so I would expect hiring outside expertise seems would usually take a back seat to just buying supplies.
Not sarcasm. Yes, supplies are one of those first things as well, but I've been to plenty of charities to note that when things get overwhelming (and it's very easy to get to that point, even before they realize that's what's happening because they're so busy with other things), they need outside consultants ASAP.
Often times, bookkeeping and organization become some of the biggest chores when a charity that gets big. It's quite something to watch someone manage a charity with just a bunch of Excel sheets, but I've seen that in action.
