For repairs are you or your techs billing on the job, or letting the office manager/secretary/you do the billing later? I do both but am actually doing more billing from the office now. I would like my money right away but that is when my customers B.S. with me and take up too much of my time. If I tell them I will bill them later it lets me get to my next appt on time. But on the other hand now I have close to a weeks worth of billing to do since office manager is out of town this week. But at least it's cold and raining/snowing so I have cancelled todays jobs!!! As much as I'd like to get it done the evening that I do the repair, I am working from 7 am to 7 or 8 pm right now. Make a few calls and pass out watching hockey or baseball on the couch by 9.
