We are in the process of adopting a few new policy's for 2007, one of which is requiring our residential customer's to pre pay each month. I know a few of you guys do this already and I have a few questions, if and when you are unable to mow due to dry conditions what do you do? (refund or credit their account, show up and do 30 dollars worth of work?) Unlike a "seasonal contract" where you have to show up and sometimes do unnecessary work no matter what because they paid for it, I thought this might be a better alternative and hopefully eliminate slow and late paying customer's. Any feedback is appreciated.
