Yea this article really should have used "accounting" instead of "finance" (or more specifically, operational accounting).

Right, like, if you're a programmer going into a project-for-finance/accounting-team at your large megacorp, and don't know if this article is the right subject area, just ask the finance/accounting person about "year end close" and see if they get a thousand yard stare or not. If yes, this is the right article lol.
