Better to bill for each service or use a March - November (or similar) fixed monthly charge that covers the maintenance services the customer wants? One time services such as mulch could be billed seperatly or included.... Two commercial properties pay me 12 months a year, all we do in winter is a weekly trash pickup on lawn and parking lot, and snow removal on walkways. Advantages to me are: I mow as needed to keep things looking good. No OK necessary if more than the weekly mow is required. Bed maintenance and other tasks can be done when I have free time, and is a great fill in for when I get done with the days work a few hours early. Steady money coming in........ What do you folks think of this type of set up?
