How do you handle customer call-backs without losing your shirt?

Managing customer expectations ks one lf the hardest things I've had to learn to do. Before and after photos are a great way to cover your butt. My best suggestion to avoid the call backs or at least minimize them is to do a thorough walk around after the jobs is complete with the customer. This way if you accidentally missed a spot it can be taken care of right then. Its a fine line to walk for sure
