It’s so easy to use! We upload our agreements, contracts, accounting paperwork, waivers, etc. then add a few quick fill in or signature spots and send it off to clients or vendors for signature. Easy peasy. And we love that we always have a record of signed docs showing when they were signed for our records. And the reminder send is great for forgetful or busy signers.
