The main benefit is around workflows. First and foremost, if you are in a position where you need external people to sign documents (say you're a photographer and need signed releases), it's a lot easier to send someone a link to the standard document and get them to sign a release then to email them and then call the person and walk them through digitally signing a document. Especially if you're doing this 50+ times a year. And you typically get the documents signed much quicker. It's pretty much the difference between having to mail in a check for every payment vs using a web portal. It's more convenient and there's a faster turnaround time. Oh and you've removed the risk that something isn't signed correctly (was there a section that wasn't initialed?) or that something was redlined. It's certainly not for everyone or every business, but there are certain use cases where the money is well worth it.
