What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
The site is a bit slow, and often will freeze during filling. Otherwise it is well worth the $72.00 I paid although it was supposed to be a free trial for 30 days.

Professional look! Got to know about PDFfiller because we use Salesforce at work, and these two are compatible. Taken together - tremendous time savings, at least several hours a week, i'd say! Longer contracts might need a while to get fully visible on the screen, but no rush here What do you think about this review?

Daniel I was disappointed to find that PDF filler had automatically charged me for a subscription I did not agree to. I felt very stressed when I saw the sum of money that had left my account this morning. I contacted the helpline via the chat service they offer on their website and I spoke to daniel. He was extremely efficient in his help and immediately refunded my payment and canceled my subscription. I would like to leave a 5 star review for the customer service I received despite my initial disappointment in PDF filler.
