I just started doing this to my clients and told my crew to start handing these in. What it is in a nutshell is, we have full service accounts for residential clients. We would be there every week and we would write out on our sheet what we did, ie) lawn service, flowerbed service front and back.. After the crew is done, we would then hand this sheet into the customer's mailbox so the customer can come home and read what we did to their property today. I find this solution the best way, cause some of the clients think we never showed up and in fact we did.. How many of you guys do this? I know once you get 50+ customers it will be an issue, but oh well.. What are your guys feedback on this issue?
