It is being used across the whole organization. Anyone that needs a verified online signature has used airSlate SignNow. I have to use it with documents that I submit to the government. I don't have to scan a document that I signed but just use airSlate SignNow.

We are trying to go paperless in our office and this has allowed me to do that with the documents that I am responsible for. airSlate SignNow provides a time/date stamp which helps in record keeping. It is very easy to use!

I have only one use for airSlate SignNow and that is to create a PDF document that has my signature. I have not been disappointed with that use.

A very worthy consideration for your electronic signature needs

5

Verified User

We use airSlate SignNow for engagement letters and other documents requiring client signatures. It allows our clients to electronically sign documents without coming into the office. They can sign from mobile phones, tablets or computers.

You can choose to password protect the esign request. You can choose to email a signed copy of the document once completed or withhold it if there's sensitive information that you don't want sent via email. Allows clients the ability to sign from almost any location and on any connected (data or wifi) device.

I've only reached out a few times to support but each time my issue / need was addressed promptly and thoroughly.

This works well for legal documents that don't require KBA. Great for virtual office solutions and for a rush signature request. I see this working well for CPA, attorney and insurance industries.
