I didn't know that PDFfiller would charge me a few after a lengthy form that I had to fill, I paid the fee and left a comment about the experience. I promptly heard back from a representative who made things right without me asking for anything. Customer service at its best!

Easy to use no time at all to adjust to figuring out the layout and process of using the system and the trial is great to see if you are applicable with using it highly recommended.
Great program. It did everything I needed and more. Some of the best customer service I've ever experienced, right at the time I"ve been having a problem. Copies of online chat sent to my email to remind me of how to deal with issues in the future. I'd rate these folks an A plus.
I needed to turn regular electronic forms into fillable ones and submit electronically, with a signature and by a deadline, during the pandemic. I was early and complete with this program!

ease of completing the form - that makes it look much more professional than a hand written form.
I like the ease of being able to put all my information in on any form. The software easily moves you from one field to the next to populate. Everything looks much more professional than a handwritten form.
I don't like the fact that I cannot save my form. I can print it but it saves as a blank form. Maybe I am doing something wrong, since I just started using it, but it did not save what I put in.
Extremely Useful, Slightly Non-Intuitive
Love the program/service/software and all its online functions, including the US Legal Forms integration for documents like wills and trusts. But it is a little clunky/non-intuitive in terms of user experience and interaction–be prepared to spend time clicking around to find not only your own documents, but also the service's libraries. Looking forward to integrating with third-party/external cloud storage.
What do you like best?
Easy to use. Very little start up time. Comprehensive set of features
What do you dislike?
Being in the cloud does require upload and download steps
What problems are you solving with the product? What benefits have you realized?
I use it daily for contacts and client documents
What do you like best?
Really a good tool to utilize for editing and transforming the documents.
What do you dislike?
Erasing any content in the document is little difficult.
Recommendations to others considering the product:
Very good and useful product to use.
What problems are you solving with the product? What benefits have you realized?
we used this tool mostly for the editing and get some digitizing the document.
