What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
What do you like best?
Allows unlimited potential to edit virtually any document and send it electronically or conventionally. This software is a time saver/life saver.
What do you dislike?
The drawback. The Eraser tool. This tool could use some work as far as the shape of the tool. The option to be circular as well as the normal shape would be of great assistance when editing. A competitor of yours, sorry to mention uses an eraser too that is amazing and I have thought of switching simply for access to the editing qualities of that software. It allows for the one time purchase of their software and I would not pay monthly fees to maintain it either.
Recommendations to others considering the product:
Try out the product and use it!! See what you are missing!!
What problems are you solving with the product? What benefits have you realized?
The editor allows our office to clean up and mark up documents received in our office such as lease agreements or forms attached to a policy which either enhance or negatively impact the clients coverage from year to year. We directly not on those forms in our proposals during renewal negotiations so the client has specifically seen and reviewed how the coverage impacts their insurance needs.

What do you like best?
The upside is that it's very efficient and expedites completing forms effectively. I have used other software and didn't find them to be easy to navigate or efficient.
What do you dislike?
The downside is that sometimes the text doesn't align when filling in forms I have to complete from other service industries. Also, when PDFfiller is the default PDF it does not print without having to refresh several times.
Recommendations to others considering the product:
This software is really good and does make my administrative work easier and less tedious. There are some quirks but when I have experienced them, the support received was expedient and exceeded my expectations.
What problems are you solving with the product? What benefits have you realized?
It has really helped me to complete the necessary documents in a timely manner when there are no glitches. I love the easy access to my documents when completed.

Exceptional Support ...
Exceptional Support ...I purchased an online PDFfiller annual plan for $120 by mistake. I really only wanted to try it for a month. Anyway, as it turned out, it was not a good fit for me so I requested a cancellation. It is one of the most hassle-free refunds that I ever experienced ... was done overnight for the full amount. I am truly impressed and will gladly do business with them again.D. McPhersonEntrepreneur

PDF Review
The ability to get a signed work authorization within minutes of sending to the client.
There's nothing I don't like about this software.

My Issue
Only real issue I have is there doesn't seem to be any way to save the same PDF after I've modified it with the sight. If there was a way to do that I'd have probably given 5 star

Handy programme for the home office
I'm still getting used to all the available functions, but so far am enjoying being able to combine various documents, and edit and sign .pdfs

This is a wonderful software to use
This is a wonderful software to use. No more paper-printing and scanning in. I just do everything electronically, it saves the environment as well as a lot of time.

PDF when u can't PDF
Overall, this is a great software. I use often , and find it very helpful.
I mostly enjoy being able to use this software on my cell phone, and then able to complete PDF's when normally this would not be possible.
I love this software, but it is sometimes difficult to use. The features are not as basic as I'd like.

Wow, just amazing service. So fast and easy. I really think this is the way to do business! When we take care of the small details and create a system that allows people to get their money back so quickly. That is a good model of success! thank you for being so pleasant to work with.
