Do you actually know which of your businesses made money last month?

I run more than one business, and for a long time I could not have told you, with a straight face, exactly which one was profitable in a given month. I had a general feeling, but no real number I trusted, just totals across bank accounts that never told the full story.

If you are running two or more businesses right now, do you actually know this month's numbers by business, or are you working off a general feeling too? What made you either build a real system for it, or decide it was not worth the effort yet?
