The feature is coordination of who to send it to and when, is it's own business, not the part where you slap a picture into the pdf and or generate write-once-read-never digital signature blob into it too.

The actual business here is the promise to keep the logs and the process to ensure you can connect the person who signs the document with the document and time, so in a very unlikely event it is being questioned you can testify that signing by a specific person happened or not. The more certifications you have for the process and the software/infra that implements it, the better you can sell.
