User in Insurance

What do you like best?

Very user friendly and intuitive. I can set up multiple signers and then add my own when they're done. A great feature I use frequently is the merge option. If I have 2 or more PDFs that need to become one, I can do that here without buying a different program or the full Adobe. They have an app that I use frequently as well and the syncing between the app and web browser access is seamless.
