It has been a very interesting experience, my first time doing my return with your company. I won't need to use your service any more, so please just bill me for this one time only. I'm 89 years old and closing down my accounting business @ 5/31/15.

I found the system complicated for someone not very experienced with computers. I still do not know how to find, on your system, the forms that I have completed. Where are they? How do I save them to my computer? I will keep working to find the answers.

I am delighted that I found this PDF filler own line. I tried Adobe; however, I could not understand how it works. This is simple and easy to use. It is not difficult to drag and drop a file and then begin to fill in the proper document.

It was a little difficult to navigate at first, but has allowed me to begin to file paper claims with insurance companies for a small medical company. Help was quick when I asked. Alignment is a little off, but it gave me a good, cheap start.

PDFfiller was easy to use.
PDFfiller allowed me to edit and submit my application easily without much effort.
PDFfiller allowed me to move the curser to start typing over the form questions. While this was not a hindrance it did take time to get the curser back to where it needed to be to complete the application. This small flaw was not enough to prevent me from using the application.

Katie's pdfFiller Review
My overall experience is wonderful!
The most impactful feature is being able to easily fill a PDF, download it, and send it to people.
I least like how hard it is to start a text box on a PDF.

I AM STILL NEW TO THIS BUT I AM FINDING…
I AM STILL NEW TO THIS BUT I AM FINDING VERY HELPFUL AND RESOURCEFUL FOR MY BUSINESS AND FOR PERSONAL USE.

What do you like best?
Very easy to upload my documents, clean them up and edit and add information. I like that it stores all my documents that I've worked with.
What do you dislike?
Printing from the site has so many print windows to go through.
Recommendations to others considering the product:
Easy, Cost Effective. There is not a lot of features to overwhelm someone. For us, it works great as we only need to edit information on new documents but only receive the originals on paper so this is the easiest to get them filled out, and into electronic format for future use
What problems are you solving with the product? What benefits have you realized?
We complete our bid documents on this program and the PDF filler keeps the information professional, legible and I can go back and edit as needed. Easy and Cost effective solution for our small company
