Collect Electronic Signatures in 24 Hours

  • 3 Weeks by Post

    The traditional way is not only lengthy and more expensive, it also comes with the risk of contracts getting lost or destroyed—paper is terribly prone to destruction.

  • 1 Week by Email

    Email is a step in the right direction, but not the goal itself! Your client still has to print, sign, scan, and convert before returning the contract to you and finalizing the process.

  • ± 24 Hours With eSign

    Once you hit the button, your client just has to open their email, click on the link, and sign the PDF—no printing, no scanning, no fuss. Digitally timestamped and ready to go!
