What do you like best?

I enjoy airSlate 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 airSlate 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!

Great user friendly eSignature platform!

What do you like best?

Very user friendly and easy to use as a document sender and a document receiver. There are constant updates to the site to allow more functionality. Since starting with airSlate SignNow there are things that I always hoped the site had and before long, those functions were implemented. For example, uploading multiple documents at one time instead of one at a time as well as adding and deleting documents from an already created template. I also like that you can replace a signer when a document has been sent because sometimes the email provided is incorrect. I like the direction that airSlate SignNow is headed.
