Ok so I have always just done yards as a "Call when you need me" type of thing. I have been telling new customers from this past year that I do weekly or bi weekly to keep from customers wanting to wait 3 weeks or more. I am wanting to get ALL of my accounts on a schedule. Whether the schedule is weekly or bi weekly I don't mind, I just want them to all be on a schedule. I'm just trying to figure out how to notify the customers in a polite way as to hopefully not lose any due to the change. Anyone else done the same ?
