On a day that I was going to really need my PDFfiller, the service was interrupted. My auto renewal had frozen up somehow and I couldn't access the service I was paying for. I immediately contacted customer service and notified them of the issue. To say that they went right into action to fix my problem would be an understatement. PDFfiller - you're service is great. You're customer service is AWESOME. Thank you for not only addressing my issue quickly and efficiently but for going above and beyond to make up for the inconvenience to me.

The UI is outstanding and very effortless. Very impressed. My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun. Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

Very easy to use. Great for completing Government forms. Minor mistakes easily corrected and the end result is much neater and legible. Saves time and paper by not having to print forms, complete them manually then scan the completed form.

Love this tool. Very intuitive and well built webApp (UI and UX are great). For the UX though, it can be a bit tough to jump in and out of different modes (editing which is "Open" - maybe call is "Fill", and tough to get to the fillable edit section). I work in Analytics - let me know if there is a career at PDFfiller for me: https://www.linkedin.com/in/andrewmiller09/
