What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
Works well. Had some issues with conversion time at first, seems to work well. Also had a few issues where the recipient of a PDFfiller email document, could not open the document. The problem may have been on their end. I just forwarded in a separate email. Great service and business tool. Thank you, Jim Kelly Fechheimer Brothers Company

I didn't know that PDFfiller would charge me a few after a lengthy form that I had to fill, I paid the fee and left a comment about the experience. I promptly heard back from a representative who made things right without me asking for anything. Customer service at its best!

I did not like the fact that when you decided to make it a service that charges you money, there was no warning. It forced you to pay if you wanted to keep your documents. I'm past that now and I am really ENJOYING it now that I am a paying customer.

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

Actual Customer Support I sent a question in via their form, and honestly expected a "word search" systemic response. Not only did I get a issue-specific response, the corrective actions were clear and documented with screen shots, making it easy for me to correct my mistake and move forward.

Excellent customer service! I used the pdfFiller when I had no access to a printer- it was efficient and easy to use. However this was a one off and thought I had cancelled my subscription. When I saw I was being charged I was concerned as I have no need for the service on a subscription, however I contacted pdfFiller customer services explaining my situation and I received a very reassuring reply from Max and the pending transaction was cancelled immediately. If I ever need the service again I wouldn’t hesitate to use pdfFiller or recommend them. Outstanding customer service.

Really very convenient, far more handier than the others selectable with a quick google search.....not sure about $20 monthly fee though. An account with a paid service per use would also be handy, but 9/10
