Back to bills:
I created a spreadsheet that has all my bills in monthly order. That way I know what is due when, it also has all the passwords, websites and account numbers associated with each account. All the information is in one place and I don't waste time searching. I prefer to set up automatic payments, or pay online and save a stamp if possible. To keep track of everything I use the program Microsoft Money. Then every month my husband balances Money with our bank account. I also like to plan it out months in advance so I can see when big expenses are coming up, like car registration, birthdays, holidays etc. so I can save.
Now, a clutter problem can occur if old bills are saved, and saved, and saved. I keep bills for two years, taxes forever, and shred everything else. So this January I went through all of our files and got rid of everything from 2008.
Figure out a system that works for you. Once a system is in place it will help to eliminate the pain-in-the-neck and stress of bill paying in your life!
