I use a control Journal and one section is finances. I have all our acct numbers and phone numbers for the companies in case someone steels a purse or something gets lost. I have a list of all the bills, total due ( if revolving credit ) monthly amount due, due date.I make a bill "schedule" 2-3 months in advance so I know what needs to be paid out of each paycheck and I know if we are missing a bill. I also balance our checkbook everyother day. I dont trust computer systems not to have some issue.. I need it in black and white
