The world has gone mobile. I need the ability to not only create, but edit and submit PDFs for signature, but also have the ability to edit them after they've been signed. The reason for this is during negotiation. If I send a contract to you, but you want to counter it back to me within a few changes , you lose that ability once you sign it because it becomes an encrypted or secured PDF. As of right now, once a PDF is signed, we are stuck and can't edit it (unless at a desktop where you can work around at using Google Drive). Your program is assuming that because initials or signatures are achieved, final acceptance has been also been achieved. However, in negotiations that is not indeed the case. We need the ability to send a document back and forth for multiple signatures, until a point where firm and final acceptance is achieved. Currently I'm using four different programs to edit my signed PDFs for counter offers, but it's not realistic when I'm on the go. It's easily done for my desktop, but for on the go I have a Galaxy Note 10 which allows me to draw and sign on the go, but because PDFs are encrypted or secured, I lose that ability once the contract is signed which no longer allows me edit or counter further.
