I am using my nice bills binder right now to put my water and swere bills into for paying next week, and for grabbing my mortgage statement to pay tomorrow.
I also just put my electric use summary in the sheet protector i have to keep those (for comparison over the year on electic use patterns). This is in the Electric Divider.
My dividers are :
I may add one for misc. This binder is purple with pinstripes and has nice matching dividers with pockets. It's really easy to use. I got it for a few bucks at staples or something when they went on sale - half inch wide. With a sharpie, I wrote Bills Binder on the side cover. I keep a purple pen that says "I am so proud of you" in the inside pocket, and also an extra checkbook that is just for writing bills.
This solution is SO MUCH easier than any other bill paying organization method I've tried before. I love it. And the pretty color makes it nicer to do the deed of check paying.
