The app itself looks really nice, but I'm unconvinced this will be useful in practice. The number of times our company has sent a contract and had it accepted without revisions is literally 0, and I see no way to customize the terms of the agreement beyond the pre-filled fields.

I guess what I'm getting at is this: if this is intended to be a tool for generating, signing, and managing contracts there must be more flexibility in actually drafting the contract language. If it's supposed to be a tool for invoicing clients, I see no way to actually invoice for contracts provided by a third-party.
