What is the name of the service?

Question

Document flow

Tell me, what is the name of such a service or application:
let’s say I have a company and I periodically need to conclude any contracts (and not only) with a client and at the same time I don’t want to mess with piles of papers (in the physical sense), but I would like to have a tablet in which the contract was provided on the screen and the client could sign with a stylus directly on the screen and after that the PDF file fell to the mail of the client and me. In general, you need to somehow keep it all in electronic form and have legal force.
Country: USA

Answer 1

Query in Google "Accounting online" and choose any site. As for international practice, I xs, perhaps in the USA "our" digital signature will not have legal force.

Answer 2

DocuSign seems to be just on this topic.
