You can use stringjob.com to keep detailed records of your jobs (if you wish).
The website also interfaces with a couple of label printers (I have a Brother QL-570, which I got from A..zon for under $100..you can find them used on CL and Fleabay). You get a pretty professional looking label. (If you end up buying the brother printer and just want the template, I can send you the file, you can just edit it with the Brother label software).
