Not sure if this is the right forum for posting this question, but since all we do is applications I figured this would be the best one. Wanted to ask how you guys bill for your services. For the last 10 years we have been invoicing off of completed work orders and mailing them out. We generate about 100 invoices a week. I just started using a new program and I was looking at printing off invoices at the beginning of the week with perforated sections. The top 1/3 is truck copy for office records the center and bottom portion will be left behind as the invoice for the customer to pay off of. Just wondering about leaving it behind with no one home. Maybe in a plastic door hanger bag? What to you guys do?
