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.

airSlate SignNow for Savings

Verified User

airSlate SignNow is used within our agency in every department. We use it to send out our contracts, NDAs and releases to our clients. airSlate SignNow has solved the issue of getting paperwork returned and returned in a timely manner. Some of our NDAs require multiple signatures and airSlate SignNow makes that much easier to accomplish. We are able to upload multiple documents to our template file and send out the required document for signing quickly.

The ability to assign multiple signers to a single document is exceptional. airSlate SignNow allows you to edit a document you have already uploaded and save the edits as though they are part of the original document in your templates section. The history feature makes it easy to go back and see how many times a document has been viewed and the exact date and time the document was signed.

airSlate SignNow is well suited for companies that send documents often that need signatures. In my industry we send around 40 contracts a week. airSlate SignNow would not be appropriate for a company that sends an occasional document for a signature. airSlate SignNow is designed to handle many documents and storage of contracts.
