What do you like best?

airSlate SignNow has simplified the process of getting documents signed and returned to us by our vendors, subcontractors and others. We've found the app simple to use and have gotten positive feedback from those receiving our invites; along with the ease of using the app on mobile devices. I feel their website does a good job laying out the features each package offers. Where we did have questions on certain features or capabilities we found the live chat to be responsive and helpful. Also, it is nice that they held a recent webinar for users to attend. Our business is project oriented so we like that invites/documents can be archived in unique folders. Unlimited invites leave the possibilities open for other uses for us.
