I don't trust computrs, since they crash all the time, I use the ever popular and exspensive "looseleaf binder". I have a weekly list made up of all my accounts, in lists by day. Next to each house, has a blank box, which I write the # cut it is for this week. I cross them off as I do them, and transfer all info at the end of the week into binder. All accounts with a "4" (4th is the final cut of bill) next to them get billed. What's good about this for me is i keep a payroll clock in/out at the bottom of this weekly printout. I then keep the paper in my looseleaf for reference if there is a question in my paperwork. I'll try to post a blank version of weekly route sheet, I'll type in a house or 2 so you get the idea....
