What do you like best?

I enjoy SignNow because it makes our workflow go smoothly. I can quickly upload and add fields, I enjoy the import fields function the most. We can use one signing link for many different customers and that helps so much with our membership renewals. Our customers find it easy to use and we have not had any issues with using SignNow. I love that we receive emails with the completed PDF document once everyone has signed, it automatically ensures that all of our members receive a copy of their signed document. We also use this for employee paperwork and with so many employees working remotely it creates a great group platform for any documents we need signed!
