Amazing software except for the licensing. I just want to pay for when I need it. For a business the month to month is great, but for a single time user it is a bit tougher.

I needed on copy of a form, that is all and I was charged 120.00, that is an expensive copy. I have cancelled your service and would appreciate a full refund. Charge me for one copy fine, but not 120.00. Thank you

What do you like best?
PDF filler is very user-friendly. My favorite features are that it saves your docs. This makes it easy to keep editing docs that you use over and over. Also, when you use the erase feature, it keeps the eraser on the same line, which I could never do on my own! At the end, you can download the whole doc, or individual pages, this feature really helps and saves time on splitting the document with other programs.
What do you dislike?
Once docs are ready, the loading time to save can sometimes feel slow. Also, uploading the docs can sometimes feel slow. This is not a deal breaker, but perhaps something that can be worked on. I think there should also be a feature where you can upload docs one after the other for the same session, and it will merge the docs (or ask if you want to) and edit them together. It seems right now we have to edit each separate if they are not already joined, save them, and then go to another program to merge.
Recommendations to others considering the product:
Have an option to merge docs, make speeds quicker.
What problems are you solving with the product? What benefits have you realized?
When I get contracts, most of the time they are not complete to be approved. This allows me to add extra details and even sign the docs. I like the stamp it adds to show when the signature was made.

Say yes to PDFfiller.
I was able to take a 30+ page PDF file, highlight areas of significance, add sticky notes and/or note boxes where I needed to remember a particular point in the lengthy document filled with legal jargon. Which made things SO much easier for me. Although I have listed a few things that I wish were different, overall the product is a great one. I had one difficult experience with a file, but otherwise everything has been amazing. I would absolutely recommend PDFfiller to anyone needing the tools it offers.
I had never used a PDF editor before. Simply due to the fact that I had a hard time finding one that wasn't trying to charge me a bunch of money up front. PDFfiller gave me a free 30-day trial. Which is an instant gold star in my books. Aside from the willingness to let it's potential customers try the product out, the product is surprisingly easy to navigate through, and I was able to download a copy of my final product free with the trial.
There are two things that I would change if I could. The first thing that I did not care for is honestly just one of those particulars that I would have like to have the option of. That being that the only highlighting option is yellow. While this is not really a big deal, it would be really nice to have the option to select different highlighting options (pink,green,orange,blue,etc.). As a college student, I handle a LOT of PDF files on a weekly basis. Anything from a single page reference list, to a PDF copy of a book that consists of hundreds of pages. For me, color coding highlighted areas makes research points easier to decipher and organize according to relevance to one another. The one thing that I noticed was a bit of a headache to deal with. I uploaded a file that needed updating. I selected a entry point that needed to be changed, and the font size automatically changed from an 8.5 to a 9. I selected the "text size down" option, and it made it a size 8. There is no option to size it back to an 8.5. This created an abnormal look to the line of text, and one or more words were different in size. I would have to go through and individually adjust everything to the same size. This may be a subtle difference in size, but as a Graduate student, these things matter in the grading process.

the erase feature should be slightly…
the erase feature should be slightly work on, like we being able to completely erase elements and not just shading it with colors.

best customer service I've experienced
Software works good, had no problem at all. The customer service was top notch. They helped resolve my account problems within the first hour I sent out the form. Polite and efficient. The excellent service provided was the last and fith star.
