I was wondering what everyone else does regarding charging for weekly lawn mowing. I personally charge per service, but have run into some issues with that such as customers claiming "oh, you weren't here that day, so I'm not paying for that cut." Even though it would be plainly obvious if a cut was skipped. Now, since I'm not always with my crew, I have to trust that they are doing the job right. I can almost 100% guarantee that the lawns are getting mowed when we say they are, but how do you prove that to a customer? That's why I'm thinking maybe a flat monthly rate is the way to go. Then you (and the customers) don't have to worry about what day you were there, as long as their lawns always look their best. What do you all do/think?
