Stop faxing and start working!

Basically every quote and agreement we use at Lennis Design, LLC goes through airSlate SignNow.com. We have found it very simple to implement and most of our customers (who are of varying computer sophistication) have no problem using it. When we re-invented our business in 2016 we didn't want to go back to fax machines so airSlate SignNow.com gave us the ability to have electronic signatures without the high overhead of their competition.

Signing a quote for your phone gets jobs started faster. Automatically exporting PDF and letting me know when the customer has agreed to the quote is very helpful. Having an online repository to re-download executed documents is helpful

Quotes and any other legal agreements are perfect for airSlate SignNow. I've used it to get 1099 contractors to electronically sign NDA's and work for hire agreements so it's very handy to have this ability and lets me do business virtually much quicker than having to deal with a fax machine.

airSlate SignNow is a great value for the money

We use airSlate SignNow whenever we bring on a new client as if puts the signed agreement in one secure place. In the past, we'd have to send a pdf to the client, have them print it, sign it, scan, and then send it back. airSlate SignNow streamlines this whole process as well as keeping all agreements in one safe secure place.

I found airSlate SignNow less expensive than some of the other apps out there. airSlate SignNow has an upgraded UX which makes it easier to navigate and add fields in the back end. airSlate SignNow makes it easy for the client on the signing side who has never used it before to figure out.

airSlate SignNow is great for businesses that sign a lot of agreements and need to have them in one place. It's great for getting documents signed by people who are not in the same physical location. It's also great for businesses that have to frequently go back and pull those agreements since the search function works very well. It's less expensive than it's competitors for the same functionality.
