What do you like best?

It is user friendly and I cannot navigate the system very easily. The options of being able to copy the link and place it on another page allows me to use sign now very easily with other programs.

Get system for small businesses

What do you like best?

In own and operate a small business and this has been great in helping to close more business. I was printing out large amounts of paperwork for the client to sign before we could start helping them with their business. The problem was that the client felt overwhelmed and would delay in signing it until they took it home and read all the paperwork. Now that we have SignNow, they can look at it online and sign our agreement faster. Plus it saves time for me and my business trying to get this part complete. The customer is always looking for the easy button and this helps. We can also add this to our tabet setup so customers can sign up on the go with our team. Driving down operating costs while maintaining a high customer experience is what I strive for as a business owner and this provides the tools needed to grow.

What do you like best?

User friendly, easy access, clients can use it fast and use it. Clients can use the system through their phones. Easy to understand how the app works. Also the price is pretty reasonable for the type of work I use it for. Guides the clients through signatures and what they need to sign next on the application. The simpler the better, the more easy access the better.
