EXCELLENT. WOULD LIKE TO HAVE THE UNAVAILABLE FEATURES SHADED GREY. AND NOT VIEWED AS ABLE TO USE, AND THEN FIND OUT I HAVE TO "UPGRADE" TO NEXT LEVEL TO USE. THAT BECOMES ANNOYING A MAKES ME USE PRODUCT LESS

Too easy to get into FONT setup and not get out and return to font specified in document. I only wanted to get the lowest priced version, not discontinue.

PDF Filller Frendly Support Person
I had Anna, as a PDF friendly support person and she was extremely helpful. I had issues with the account and she was eager to fix it and then I had issues with the form and the same excellent response. She was not only knowledgeable, but fast and very, very helpful. She used many ways to explain the issued including screen shot. Thank you Anna.Carolina

Works for everything
Overall I am a fan of the software. I know not everything is supposed to work 100% of the time and things will happen so that doesn't deter me from using the software or recommending it someone else.
I liked the ability to install and go, this software worked for getting documents in, filling them out, and getting them back out. I like the options and the ability to even save some data.
Sometimes it has crashed or felt a little clunky. I am unsure if it is saving the data but during the saving process it has crashed on me and that is something i wasn't as much a fan of.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL

User interface can be better
This is a pretty good website to merge pdfs. Overall has everything you need. I do believe the user interface can be easier to use for those who aren't as tech savvy.
