I found this earlier in the year as a solution for my problem of forever losing bills and finding them after they were due. Each month has a pocket that you can put the bills in as they come in. There is a place on the pocket to write the paid information down as well. In the front of the book is a zipper pocket to put pens, stamps, and whatever else you may need. Ever since I have put this to use, no late bills at our house!
