I've recently bought some financial software for my Mac, can't recall its name but it's pretty good. I can import my credit card statements into it and categorise all my transactions so I can see (and report on) what my money is going on.

I didn't try to automate it; I just wrote everything down in a little book, even $0.50 at the grocery store and put it all in a spreadsheet at home. Unless you really pay everything with your CC (which here, in Europe, would be very strange), you would miss things, or at least not know where they went.
For instance; I get $100 from the ATM, I pay part of a business diner with that for $90, then I have $10 left. The $100 is registered on my CC so $100 goes into my business account, while $10 I spent on some magazine at the train station while I was bored. The $100 for the business would be; 'wow we got the client, well spent!' while the $10 went into the black hole as I won't ever touch that mag after getting off the train.
