What do you like best?

I researched a few eSignature software apps and settled on SignNow a couple years ago. As CFO and head of business development, I use SignNow frequently for partnership agreements and shareholder docs. I like the uncluttered user interface, which makes using this product straightforward and fast. It also saves time to upload commonly used agreements as templates into SignNow. Adding additional users in our organization is easy and cost effective.
