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.
