Not sure yet why the W2 would not send to IRS. the button was not lit up after I completed all of my information into the W2 forms. I doubt that I will be able to afford your product due to it billing annually. Also, the price is too high for my budget. -EPOC Bookings

Excellent program, way easier then DocuSign Super easy to use and if you need tech support they are there for you. Its very easy to use and very informative. A couple of clicks and you are done. Tech support is great as well! It would be nice to get an email when the client opens the contract I send, rather then always having to check

I have been using ********** and AirSlate for over a year now to create digital documents and digitally signable documents. The system is very user friendly and all the options to automate my digital forms are logical and intuitive. I highly recommend this product for creating digital forms.

What do you like best? It's ability to upload pretty much any type of document What do you dislike? I cannot really say anything I dislike about the product What problems are you solving with the product? What benefits have you realized? The biggest problem we have is that we receive uneditable documents that we are able to edit easily with PDFFiller. It's super beneficial because it saves us so much time.
