- Disclaimer: the HelloSign tagline that's displayed here in PH seems out of date. They work with all documents, not just Gmail / Google Docs. I've found HelloSign to be among the simplest (vs. DocuSign and PandaDoc and a few others) to use and friendliest for your signatories. And, if you're a low volume user, it's free.
- I use PandaDoc for all things e-sign because, unlike other tools that are like putting a piece of glass on top of a word doc, PandaDoc is an HTML document. You can build and edit content/ templates right in the app. I also like being able to track document activity and customize my design with CSS. People always comment on how easy it is to complete a PandaDoc.
At the moment it does the job I need - paste the signature field as well as dates and names on the contract and send it. It also syncs all my documents between my devices. And it is cheaper than their nearest competitors, but definitely only on its start.
Probably the easiest way to get a signature.
Scan, upload, define signature space, sign, define signature space for second party, send email, wait, get the document back with both signatures.
