Docusign effectively does this with all of its integrations. If you run on Salesforce, it's really well integrated. And if not, they have a great API. You can programmatically generate an https link and send that to your customers as part of your existing workflow. You email them a link or even just open up a new tab / overlay a browser. They can log in with various SSOs, they sign the form, then come back to the next stage in the workflow.

And there we go - why DocuSign is a 50b business.

Sounds like OP doesn’t understand the complexity.

Can you replicate DocuSign if you were given 50B USD ? Well, then you know if it's overvaluated or not :o)

What most people posting here don’t realize is that they couldn’t replicate docusign’s 50 billion dollar business with a copy of the source code and a time machine.

I could replicate Dropbox with rsync with far less than that (h/t to BrandonM).
