A good percentage of my customers like to leave it under the mat or in a specific place each cutting rather than being billed. I like it that way myself, no mailing, no contact, no delay. Do the job pick up the check and move on.
Man, I got people running out into the yard with cash in hand, chasing me down in my truck, and even coming over to the house saying. "Oh, Joe, we weren't home when you came, so here you go!" I always have to tell them jokingly, "Don't worry, your credit is good with me." I find that it is the black folks I work for that are the most concerned about paying. They always say things like "Well, we wanna make sure that you come back!" I guess I am blessed.
I bill on policy. I do not like the few customers we have that demand to pay when we cut. It takes more time than entering a date in the computer. Sometimes they like to talk etc, and although there is a time for customer relations, these same handfull of people are sucking it all up!
