What do you like best?

The use of this app is so extremely simple and easy for the advanced tech person, all they way down to the not in the least tech savvy person. I have had all walks of life find this easy to use when we were not able to sign in person. It is also easy for me to set up signatures from my phone or my laptop, in no time at all. The ease of use for both sides, is what I like best.

What do you like best?

We use sign now for our real estate contracts and I can’t begin to tell you how many hours it saves us on every contract. Without airSlate SignNow, we would have to chase people down, worry about having them print out, scan, and then remember to send us back their signed documents. airSlate SignNow removes all of that headache because everything is done electronically. It’s easy to setup and very user-friendly, so even our least tech savvy clients/partners can use it with ease.

What do you like best?

I'll admit, airSlate SignNow isn't perfect yet, but they have Docusign beat hands down when it comes to the control of the tag placement, the things you can do with the tags, how the tags work, the pricing per user (3x cheaper than Docusign and we get bulk upload!) and BEST OF ALL - we don't have to run our loan doc packages twice anymore, which we had to do under Docusign. Now we send the document through Drawloop, with delivery option of "email", AND at the same time, we can right click and save the package, and when we manually upload it to airSlate SignNow, it recognizes all of the tags! With Docusign we had to run the package twice: first to email it and second to send it through to Docusign because Docusign does not see the tags if it is first saved then uploaded. You have to use a template or manually place the signatures and we have 80 tags per set of loan docs! Another thing that airSlate SignNow can do is utilize tags that are already in the document, so you don't actually have to convert all of your Docusign tags to airSlate SignNow tags. Took us a while to figure that one out, but pretty nifty so we didn't have to recode all of our documents. Although now we use Drawloop Components to place the tags depending on the Delivery Option Name, so not necessary. Another AMAZING thing: bulk upload through a .csv file so we can send out a set of loan docs to hundreds of investors in under 10 seconds. Try doing that with Docusign without paying extra. There is one thing I really love about SaaS and that is the more features they have and the more advanced things they can do, the more I can take advantage of them and make our system even better. And I haven't even finished figuring out all of the advanced features of Sign Now!
