airSlate SignNow is a Good Product That Increases Conversion Rates

Andy Taylor

We use airSlate SignNow to have new clients sign their professional services agreement with our firm. All of the attorneys in our firm use airSlate SignNow. We also occasionally use airSlate SignNow to have clients sign other documents, such as settlement agreements or authorizations to allow us to obtain their employment records and that sort of thing.

airSlate SignNow provides a detailed audit of who signed the document and when and where they signed it. airSlate SignNow allows users to customize the email that goes to the signers.

I have only had to use airSlate SignNow's support once, and that was just for a general question (I wasn't having a problem with the product). The response was very timely and very helpful. Other than that, I have not had to contact airSlate SignNow's support department because I'm always able to get my questions answered using their online support.

We use airSlate SignNow so that when clients sign up with us, there's very little delay between when we speak to the client and when they are able to sign the contract. It has increased our conversion rate because we no longer have to have clients print a contract, scan it in, and email it back to us.

airSlate SignNow - The quickest (and cheapest!) way to get things signed

Chris Ammann

airSlate SignNow is used to efficiently and quickly have candidates sign offer letters, or for signatures required from employees for HR documents. It solves the problem of having a candidate print, then sign, then scan their offer letters back to us. So the ease of use for our candidates makes it a worthwhile investment for us.

It's one of the cheapest services out there for digital signatures. It offers a comprehensive audit trail of when items were signed, and by whom. It's quick, and very easy to use Very nice GUI.

I've only had to contact support once or twice, but both times my issues were resolved quickly.

We use airSlate SignNow for our candidate offer letters, where it helps us to quickly gain a signature from a candidate in a market that is so competitive that at times, the quickest company to get an offer sign will often be the company that makes the hire. It also shows a level of professionalism in presenting your offers.

Easy to use and Intuitive

5

Ryan Spaulding

I used airSlate SignNow to sign leases. The software is excellent and intuitive. Up to this point, I have used 3 different eSign software services. airSlate SignNow was the best in my opinion. Other software might offer a few more features, however, airSlate SignNow was the easiest to use and navigate. I literally needed it to collect some signatures and initials. I didn't need the fancy stuff.

Ease of use -- Whether on a computer or using the app, it was easy for me as the sender and easy for the recipient. Intuitive interface -- Most of the time, the recipient of the documents was using airSlate SignNow for the first time. I never encountered a situation where they could not figure out how to use the software.

I would recommend airSlate SignNow to anyone who wants a solid eSign software.
