After looking around for a bit-here is what I found-

proposals, as well as create verifiable content for training materials
and courses etc.
Thanks for your help

My preference would be to use PDF for any document where the
formatting matters - with Word documents where the formatting was
critical, even something as trivial as the recipient having a
different default paper size can make the displayed document look very
unlike what is intended.
I am still interested in the business need, if you have a moment to
explain? I understand how digital signing works, and what it proves,
but I am trying to imagine a scenario where it matters and where the
local jurisdiction is geared up to accept digital signatures as
binding evidence. are you looking at a fully "paperless" scenario

to prove this; we both retain doubly signed copies of contract for
