This might be a stupid question but it was real windy last night and alot of tree's feel down. I have a couple customers that have small and big branches down. I saw them while I was driving by today. Im getting my chain saw fixed. SHould I charge them for branch removal. There are some small ones and some big ones. Do I add it to there bill at the end of the week or ask them to pay me up front or what?? This is my first time dealing with a little tornado affect with my lawns. How much do you guys charge for that kind of stuff.
