How long do you let a account go unpaid before you cancel it??? I have a account that I just started having the last of the summer. The guys grass was way long over due to cut when I first cut it an he was happy and paid me on time. But since then I have cut it 3 more times with no payment. I have tried to collect but it always" next friday" or "waiting on a check". When do you say enough is enough. A newbie very frustrated.
