pdfFiller scores top ratings on review platforms
I loved using the program. It helped on saving paper while allowing to update documents without having to print, use white out, and scan the updated document. It was really the only feature I used, but i know there was so much more to the program. I would love if they created a pay option that was cheaper than basic or reduced the price of basic for those of us who just need it for one or two functions. It was very easy to use and i wish i needed it for other things. Overall still a great program and i would recommend it to anyone. I am only giving it 4 stars due to me just not needing it for a whole lot.
I had a misunderstanding with PDFfiller . . . thought that I had cancelled my subscription immediately after discovering that it didn’t fit my needs, but something went wrong, & I was charged for a one year subscription at the end of a 30 day trial period (didn’t realize that I was in it). When I went to the Customer Assistance website & explained the problem, PDFfiller immediately refunded the amount charged. Honorable people!
