Hi guys, i just finished developing a web app that helps with client sign-offs! Signoff.me
in a nutshell:
You basically create a check list for your client, attach files then send it.
Your client gets a link to your list (you can brand it to your company too!) they can then sign off on it.
You then have a record and pdf for your records if anything goes wrong during or after the development process.
The idea behind it is that we want clients to sign off on specific tasks like "i have read page 2 of the document" or "the logo is a perfect size and i approve it" there is an ability to create comments as well as revisions. However we want this to be just a simple sign off people can send to clients and not a collaboration tool.
We also automatically create a pdf file if user submits submits a pdf or doc file and then stamp it with their name after it's been approved.
You can make a free pro account that allows you to manage sign-off lists easier (with list templates, archiving etc) or you can use the lite version to do a quick test and get a fill of it.
The site is here: signoff.me
