I sometimes use an Analysis Pad to keep track of payments in our business and even for such mundane things as tallying bills and expenses. I have a number of National Brand Premium Analysis Pads that I use on a fairly regular basis.
These pads are made by Avery Dennison, have four columns and 50 sheets on 8 1/2 x 11" size paper. The paper is color balanced for ease on the eyes and also erases easily. The lines on each sheet are precise and will not smudge.
I know that one of these days I will get software to help me with my figurework, but for now these analysis pads have come in handy and have really helped me to keep track of my numbers (which isn't always easy for me because I hate anything to do with math).
Each Analysis Pad is three-hole punched, and the Item No. is 45-304. Anything made by Avery usually turns out to be a good product, and I know that until the day that I purchase computing software, I will be using these pads.
Update On Jul 13, 2010: I use these analysis pads quite often when I'm getting tax info together and working with numbers in other ways. They always help me to keep track of my budgeting and have come in quite handy.
