I use the MSMoney software program to track all of my expenses and income. When I receive a bill, I enter it into the bill section of the program, and it helps me to keep track of when bills are due. I also enter in all of the income that I receive. It helps me to forecast how much money I will have in the future.

If you are looking into buying a software program to help you with your personal finances, I highly recommend it. It is very user friendly.
