I was in a real pinch with only a couple of days left to send out 1099-R forms and facing having to type them on an old-fashioned typewriter, until I found PDFfiller. You saved me hours of frustration and extra work!

A very useful product, although a bit tricky (complex) to work with. I don't fill out enough PDFs to make a subscription worthwhile, even at the discounted 75%-off rate. Thank you for allowing me to try it!

Great customer service! The site works very well and is easy to navigate, and when a miscommunication happened on my end the company was extremely polite, helpful, and quick in their response. Great customer service!

Very professional and good customer support I forgot to cancel the auto renewed subscription after my free trial and they got back to me within a day and were also very responsive. I got refunded immediately even though it was my fault for not cancelling.

I large amount of relevant templates, especially the collection of tax and business documents. After searching all over for a form builder, a template library, and a document signing tool, it was so satisfying to stumble across a site that can be all three, do it well, and even be affordable to use!

What do you like best? I work remotely, don't have a staff or colleagues at my finger tips and find myself in constant need of sending out advertising agreements in an efficient manner. I have the ability with PDF filler to quickly revise and add to routine contracts efficiently. What do you dislike? The process, of saving and downloading revisions sometimes requires extra clicks and can be simplified. Recommendations to others considering the product: a good option for a quick fix What problems are you solving with the product? What benefits have you realized? Quick revisions are customization are the greatest benefits for my work

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.
