I was thinking about trying something next year and wanted to run it by you guys. Let's say that in my service agreement that I outline the weekly charge for mowing service and then have a condition that if it rains, their lawn may be done the following week at a different rate. So, if the lawn costs 38.00 per week to mow and rain prevents the mowing of that lawn, it would be done the following week at 45.00 due to extra growth. NOTE- I would not make this a practice for everyone, just those lawns that don't grow that fast. I can hip pocket them for the following week while I catch up on others after the rain. Thoughts?
