I have found that PDFfiller is very simple to use and offers quite the range of options. Matter of fact, to date, I have yet to figure out anything they don't offer that I would ask to be added. Quite a happy client!

Honestly- it is not straigth forward tool- you need to spend time and learn how to use it so it is not exceptionally user friendly. I found SignNow very complex!

I was able to upload and edit a document. I sent it to someone across the country who printed, signed it and sent it back. I then e-signed it and submitted it to a third party successfully.

A must have!! This is a must have for anyone that uses PDF's alot. It can save you a ton of time. This software is awesome, I love that you can take any PDF and alter it. It is easy to use and comes in handy. I wish this software was more set up like Word, as in the features and where things are located. Some of the features are hard to find.

What do you like best about the product? pdfFiller by airSlate saves me so much time when dealing with documents . You can easily share documents and ask for signatures via messages or even share them via QR code What do you dislike about the product? A bit tedious when it comes to editing the document. you would have to edit it in a word format and then proceed again with converting it to PDF format. It's a little bit too many clicks for my liking What problems is the product solving and how is that benefiting you? The ease of use is the major factor in using PdfFiller. It has help me communicate with the people I dealt with and send documents for their review and signature

Great Service - Great Support Team I used this service just once, but it was very easy to navigate the site and all of its capabilities. I thought I had canceled my subscription after I was done and forgot about it until I was charged the full annual fee. I reached out to them to see if I was eligible for a refund since I had not logged into my account in 29 days. They agreed to refund the charge and were very timely about it! I will use this service again if I ever need it again.

Having better results with the site It is a lifesaver as far as my clients being able to sign consents on the screen and get them back to me. So far, the recipients of my docs have been able to follow the instructions and sign the docs without difficulty
