Proposal software that assembles the pitch.

The proposal is where the work is won or lost, and it is usually rebuilt from the last one, at night, in a document nobody can track once it is sent.

Propossi drafts from what you already know about the deal, keeps the templates in one library, and follows every proposal after it goes out. Signup is not open yet.
