Great question! Propfire is very different in a fundamental way.
All the other apps start off by having you choose a design template and then modifying it and inserting your own content. You’re basically working in a wysiswg design editor.
With Propfire you never have to deal with a design editor or interface. All you do is input (or import) your content and it automatically generate a professional, great looking proposal. That makes the proposal creation process much faster, easier and more efficient.
