It's a very user friendly product and customizable. You can put together a professional proposal in just minutes and make changes simply and quickly if necessary.
Certain modifications to files, need to be handled by their staff, however they do respond very quickly, sometimes within 10-15 minutes and things are complete.
Great company to work with, their line is always open.
Using less paper of course, but also being able to track the proposal time line, start to finish.
