The interface of fastee is very user friendly. I like their design for all the features, but I dislike how slow it is to do things once you get used to it. Its quite difficult to navigate at first. Do your homework first before making sure that this is the right fit for your business needs. If its easy to use when you have done your research well then you should give it a go. It makes communication between our sales team and our customers so much easier than having to send them an email or call them on the phone.
