I’ve never heard of Docusign, but i know that people use notion and or google docs templates to fill out the new customers infos and send them documents. This eSignature workflow would be good idea too, I have a background in coding so I will give it a try and share with you how the workflow will be.
It seems that DocuSign now put all of their API access behind an incredibly expensive paywall. We will also review how to do this via e-signature workflow in Google and let you know how we get on.
