I am not a computer type of person, this this is a very good program. that I was able to figure out. thank You very much. I REALLY needed your help.John L. Texas

What do you like best?
I like that you can save the template for a certificate of insurance or an application and send it out that way. It still saves it as new but also creates the new Document.
What do you dislike?
The same feature that I love so much, isn’t quite as easy to navigate on the App. It’s super easy on the full online version though.
What problems are you solving with the product? What benefits have you realized?
Super easy to use on the go with the App access. I live that part of it.

PDFfiller is a GREAT program with INCREDIBLE customer service! PDFfiller is a GREAT program! It is very easy to use. It helped me tremendously when I had a project and needed to fill out literally hundreds of documents online. The program worked very well, was incredibly responsive, & even kept all of my documents for easy access as well. Most importantly, however, is that they have absolutely INCREDIBLE customer service! I used the chat feature and it was totally painless and even enjoyable. I was treated very well by the chat rep (Paul)! I am a single mother who is trying to start a small business with VERY limited funds. I meant to cancel my plan before my 30-day trial was over. Like so many other times in my hectic life, I guess I forgot! I was quite anxious about it as many companies charge high cancelation fees if you fail to cancel during the trial. There was no need to worry though. I simply logged into my account and then I saw the chat feature. I chose to use it even though I was hesitant to do so (many companies do not provide very good customer service through chat). The response time was extremely fast. I asked to cancel my membership and he replied right away that he would do that for me. Here is the best part, he then proceeded to ASK me if I would like a refund as well!! Now that is WONDERFUL CUSTOMER SERVICE!! Thanks so much, PDFfiller & Paul! I will definitely use them in the future and recommend them to my family and friends. You just do not see that level of customer care combined with great products anymore. I was quite impressed!

PDF Filler is a wonderful application… PDF Filler is a wonderful application for downloading common PDF forms (was really a boon during the recent tax season!). You can fill out the PDF forms electronically, save, and do whatever you need to with them- such as printing, sharing, etc. I love it!
Pamela Bates
creating forms for small private practice overall it is a good product once you are accustomed to operating within its rules and time lapse with commands and follow through ease of using current document to edit and create form it is slow to react to commands or does not recognize or follow commands first time you ask or click

Top Notch Customer Service: They were polite and quick to respond. Large Selection of Templates and a Template/Doc Creator. Enjoyed the easy of sending Documents for review/signature. Would highly recommend this service to anyone needing quick and easy documents for all kinds of topics.

Great to use Great to use, but wish the font/size/color of text would always remain as the original was during editing existing text, or at least show what that information is to the user.
