try service autopilot.
i really recommend it over gopher.
it does cost ou money every month and does take a little while to set up all your clients/ services.
you can print out your schedule for the day or week.
if you dont track the time on each jib when you get home all you do is check the jobs done and press complete.
it gives you the invoices automatically at the end of the month.
give it a try as it will really save you time and help organize you
