What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
some forms are not as well created. would be nice to be able to tab between fields. or when clicking in fields that should all be within the same horizontal line it would be nice if they automatically lined up rather than having to be moved like individual text boxes.

THIS PROGRAM IS VERY USER FRIENDLY. THE ONLY THING THAT I DONT UNDERSTAND IS THAT WHEN YOU RESAVE THE DOCUMENT IT DOES NOT UPDATE THE TIME OF YOUR MOST RECENT CHANGE.
2016-10-25
I love it for the most part. Just wish I could send a document to a person without knowing their email (ex. directly to their Facebook account) with the ability to view and sign not edit the document. Other than that, it's been great!

Excellent PDF Software
Overall, this is an excellent software for businesses for the many things you can do with the program.
I like that you can use forms previously created by other users of the software, or create your own forms as well. The software is user friendly, and provides all the functions we need in our business.
Unfortunately, that you have to pay to use the software. I understand that everything comes with a price, there are developers, etc. Considering the functions it provides, it is worth paying.

A must have for your business
Overall, this software is a very useful, less time consuming, and efficient addition for my business. I love that I can complete and sign required documents on the go with no hassle, without having to print and physically complete and sign any document.
I love that this software is so convenient and easy to use. Its a must have for completing and signing documents for your business electronically in a quick and efficient manner.
The mobile app for this software is not that easy to use as the online (desktop) version.

Time saver!
I have used PDFfiller for several months now and love it. It is a great tool which makes it extremely easy for me to quickly and efficiently fill out PDFs and return them to the sender. Wether it be filling out forms or signing a contract, it has saved me many many hours in the long run - and is a pleasure to use!
There aren't really any cons to this plugin - it does exactly what it says it will do. However the user interface could be improved

The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
