Several low-cost tools can help you go paperless. The best is a scanner, which works much like a copy machine, and allows you to convert paper documents into computer files. You can then change or enhance the scanned document, print it, or use it on your website. Initially, scanning all your files can be time consuming. If necessary, it's a task that you can easily outsource—or ask someone to do on an internship basis.
Depending on your budget and technical know-how, you might also consider conversion software, which converts electronic files into images. Conversion saves time by eliminating the manual process of printing and scanning documents. It also protects your documents from being changed. Once you convert a file to an image, you cannot alter the document (unlike scanned documents, which allow you to make changes).
