Simple set up and use of services. Easy to connect with customer support for questions. Support for all different fax devices including mobile phone, and ability to read a file attachment without needing multiple programs. I have been able to send files to customers via email when they do not have fax capabilities. Customer service is great! Have not found anything yet that I dislike about this software. I highly recommend it! Being able to receive files from customers quickly and easily while still maintaining a paper trail.
