Love it, I can fill in forms and not use my terrible handwriting. I get the fill on items that I look at and your app is blocking me from seeing it on the screen.

I love PDF filler. If you have any new software that you need trials to be done on, I would love to test it. Thank you PDF Filler for saving me on many occasions!!

So far I like it. I don't like that it saves it multiple times and when I try to get rid of the older versions it erases all. I am not sure if I am doing it wrong. Overall, I like the features. I'd like to see the rotating feature added. For instance, when you erase and add a new text, and thd pdf page is crooked, you can cut and rotate the piece to straiten it.

What do you like best?
I like the ability to electronically sign documents.
What do you dislike?
I wish I was able to edit the text in documents without the formatting getting messed up because it only allows for the addition of new text boxes or adding to existing ones which causes the formatting issues.
What problems is the product solving and how is that benefiting you?
It's solving the issue of having to print out and fax documents which can be time consuming. It has really benefited my company to be able to sign and send documents electronically making for a smoother more efficient experience.

The features are unmatched and the customer service has been outstanding! Anytime I have requested online support, I have received immediate and very detailed attention to help guide me through any feature, tutorial, description even with the ability to share templates or files and have customer support advise on any possible questions. This is what we've been looking for for all of our fillable forms and for obtaining e-signatures and it's at the best price point for businesses! Very excited to learn and use more of the features with PDFfiller!
