What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It would be much more efficient if multiple copies of the same form were filled automatically with the information entered on the original. Completing the documents should be quicker and simpler, no reason one has to play with font size and trying to pin point the location of the mouse to ensure proper destination in the field of entry on the form.

I was a little confused when I first began using the app, but did an online chat with their agent who walked me through what I needed to know. Therefore; I would recommend this subscription to any Commercial Insurance Agent who issues multiple Acord forms.

What do you like best? I enjoy PDF Filler because it is not as expensive as Adobe Pro, and it allows me to quickly edit, sign, and return any PDF document I would normally need to print out, and scan back to myself. What do you dislike? One dislike I have is the fact I need to download everything. It would be really helpful if everything would be automatically saved on something like a onedrive (cloud storage), where it would be automatically saved. This way, I can have a local folder on my computer without needing to go into the webpage and click download What problems is the product solving and how is that benefiting you? I no longer need to waste paper to download a form, and fill it out. Normally I would need to do this, then scan it back to myself. now I can upload, edit, and sign the form which saves a lot of time.
