For keeping track of who has what and where it is, you could try an Excel spreadsheet, or, better yet, an Access database. Using Access is good because you can build on it over time. You can start out simple and add fields for things that come up in the future. If you are not familiar with Access, you can either check with your programmers or even take a class at a local college or computer store. It may seem a hassle now, but in the long run you'll be glad you did it. You can even keep inventory of other equipment like routers, switches, and printers. As for labels, you could try Word. Use the Letters and Mailings option from the
Tools menu to create labels and print them on popular brands of labels you can buy at any supply store.
