How do you guys like to be paid after completing a job, whether it be mowing, mulching, trimming, fertilizing, and so on. Do send a monthly bill to everyone of your customers. If so how do you send them out, through mail? Do you pay for all the stamps each month or do you have one of those envelopes that don't require a stamp. If so how did you go about getting them, I am interested in finding a new way to collect my money. Right now I am just knocking on the door when I am done. That is very time consuming because some of my customers like to talk a lot. I was interested in changing the way I collect my money, so any responses will be greatly appreciated. Thank You.
