Has anyone here ever charged "up front" for lawn maintenance? I'm thinking of trying a new billing system, and am wondering what peoples experiences might have been in this regard. I'm going to be asking customers to be paying for maintenance services for the month, "up front". I figure that will save me from ever having to deal with customers who wont pay, or are just late paying. As it is.... to simplify my life, I have always requested my customers pay cash (sometimes I might let it slide and let certain good customers do a check made out to cash)... and I have not encountered too much resistance because my services are very good and customers are always happy with the quality.... so I figure it can't be that much of a stretch from going all cash, to getting people to pay up front. Any thoughts? Now all I have to figure out is how to simplify it, to give people refunds for 'rain days'. I'd rather not play the shuffle the money back and forth game.
