Would like to see a better way to organize/save files for easier opening. Would like to see a way to convert files to PDF as well. No need to send a follow-up survey, your system won't allow us to complete it without having a Facebook or Linkedin account...we know our own e-mail address and it won't accept it.

i WAS ABLE TO DO A DOCUMENT IN HALF THE TIME IT WOULD HAVE TAKEN TO UPLOAD ON MY IPHONE AND EMAIL UPLOADING A DOCUMENTS OF 27 PAGES WITH FILL IN WAS EFFORTLESS

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.

Great product
Great product, super easy to use, and they offer a very nice free trial. No scam here: it's very obvious what's free and what's chargeable.

I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.
