Sunil

Using airSlate SignNow has been incredibly helpful in moving towards a paperless business model. The app is very easy to use, and the integration with most major cloud storage providers is a huge plus. Since adding airSlate SignNow to our business model, we've found that not only does it reduce the amount of paper that we need to keep on hand, but it's a huge benefit to our clients. The sophistication of providing them all their details signed, and in electronic format provides them with a stored and searchable document in their email, as well as impresses them in the process. If you frequently deal with needing to sign documents, I would highly recommend incorporating this into your business model.

Kim

As a landlord and a tv producer, I use sign now to quickly and efficiently send and get contracts signed. I've been able to eliminate the need to print a document, get it signed and then scan it in to digital archives. I can personalize a contract in minutes, specify the areas for people to sign, send the contract by email and receive it within minutes. I also love the template feature that allows me to upload one contract and send it to multiple users - each user signing and sending back the same contract. It saves me from redundant busy work ... can't stress enough the convenience and efficiency of sign now.
