This is an excellent article about simplifying your finances through paperwork reduction and planning. I particularly like the idea of having weekly budget meetings with your spouse. If you cannot find time for a weekly meeting, start with a monthly meeting, since odds are you will know about major purchases for the month ahead of time. The increased planning will make you feel like things are organized, which promotes clarity and focus. With regard to the paper, I have found that the more I reduce the paperwork in my life, the easier it is to stay organized, and it helps the environment, too.
