"FlatRateFax.com has improved my business, because I have cut down on paper faxes, and I can send and receive faxes from anywhere in the world.....all I need is my laptop!"

"FlatRateFax has been extremely cost effective and convenient. After 3 months of use, I have saved an average of $98.00 a month. I no longer require a second phone line. I don’t waste paper from all of the unwanted faxes my company receives, not to mention, the fax cartridges not being wasted. I never miss an important fax because my email travels with me on my phone when I leave the office. FlatRateFax has proven to be a good business decision!"
