I don't have anyone on an annual contract, I just cut as needed, whether it be weekly, bi weekly, depending on the lawn, season, customer, as this is a part time job for me. What do you guys who have people on contracts do when it doesn't rain for a month and nothing needs to be cut. Say you have a contract for 21 mows or however many it is, do you cut anyway, or give them a credit towards leaves, or something. If they are paying monthly, i guess you can just collect and not have to do anything? How does that work, and do you get a lot of complaints if no cut is needed?
