What do you like best? I usually dont like to take time to review but this one is warranted and a long time coming. What I like best is how many hours it has saved us. We subscribe to several tools and PDFFiller is one of them that we use on a daily basis at the office. I cannot tell you how much time this has saved us especially while submitting proposals. We also love the fact that it has an inbuilt ability to send out e-signature similar to docusign so we do not have to subscribe to a separate service for that. If there is one tool that has given us a 100x return on our investment that is PDFFiller. I am also thankful to the PDFFiller team as they keep on innovating and adding new features. What do you dislike? Nothing really. Like I said above, this tool as delivered massive value to our company. What problems are you solving with the product? What benefits have you realized? Editing PDF docs, adding, merging, e-sign docs etc etc. Avoids us having to scan docs I mean it has a bunch of features that once you start using it you will be like WOW! This is one of the MUST HAVE productivity tools in your arsenal.
