Great until I realized I couldn't use one form to save in different ways. I had to go back and delete and rewrite for each person I was filling the form out for.

Easy to use & Quick My business is all about paperwork. Everything is time sensitive and I could not get things done without PDFfiller. I use it daily. The ease of use is so important to me. I don't have time to learn difficult programs. Easy to upload docs from anywhere, rearrange pages, make corrections, save as PDF and save or email. You can name your files and go back to them when needed. The dashboard is easy to navigate. I have used this software for years and they are always improving and adding new features. I have had trouble uploading an occasional document but customer service fixed the issue each time. Sometimes my document is too large which is frustrating, they have a size limit. Also, a document with signatures from another software company (e-sign) sometimes don't come thru.

I needed to make editable changes to a document in a short window of time. PDF Filler did the job! User-friendly and it saved the first draft so I had time to purchase a trial run of the software in order to save the final version on my PC. I wish that I could've been able to log in and get right to my previously saved work faster. The intro screen and the print screen were rather busy.

It was actually nice, easy and convenient to use. It is just that I find it expensive so I revert back to my old ways means manually filing or writing in forms. :)

So far I am really liking pdfFiller So far I am really liking pdfFiller. It's simple to use and has many tools at your finger tips that makes filling out paperwork even easier when you can't get ink for your printer, or you own your business where filling out important documents just looks much neater when done on computer than your own chicken scratch.
