First of all I've been in the mowing and landscaping business for 12 years. Here's my problem. It seems that every once in a while a customer will question if we have mowed or not. Example " we only mowed twice in August and in mid Sept. the customer receives their bill, now they think they only were mowed once and do not owe for one of the two mowings. We send out a daily report on which properties need mowing and the crews check off at they mow each property. However it always seem as though each month we will have a customer call and dispute their bill. I have read about monthly billings and I believe they might be right. How do some of you cope with this problem or maybe you don't even have a problem?
