OK guys. Here is my problem. This is my first year doing everything 100% legal and actually running myself like a professional company. I am doing good as far as marketing and getting the work but I feel that I am lackin in the paperwork side of it. I am very picky and organized but I am not sure that I am keeping all of the appropriate paperwork and have a very good system set up. Anybody care to share a brief summary of how they do theirs? Here is what I do now: 1)Print out estimate. 2)Keep copy of estimate in a folder for that customer. 3)When accepted. Give copy of contract to them and keep copy in folder. 4)When completed I bill and keep a copy of the bill with any receipts for the job attached. 5)Once the money comes in, the bill is marked paid with cash or a check # and then filed away and a receipt is written. All expense receipts are filed in the expense folder and the copy of the bill is filed in the income folder.
