One of the most amazing features of Google Docs is its ability to send faxes on your behalf – as stated by Skookum. The HelloFax add-on lets you fax your clients, vendors and customers directly from the Google Docs platform. Once you install the add-on, you simply add the fax number; the document and cover sheet will send in less than 20 seconds. While Google Docs is traditionally viewed as a word processor, it can actually be used as an invaluable office tool in a variety of platforms and settings. Since it is free to use, you can save tons of money on software.
