airSlate SignNow for Savings

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.
