I haven't gotten into the business just yet, I was wondering how you usually bill residential customers. I have read some people say $35 per mow......so do the people pay you cash every time? I have read that you can charge them monthly....are all your billings based on the customers request? Should I have some sort of plans available ahead of time, so the customers can see why they'd be paying, say $85 a month or whatever? Thanks everyone for this website! Lots of info. and help! Dan W.
