Thought it was too expensive and did not see the 70% discount for paying annually instead of monthly and do want that discount and as such a large partial refund of the $120 we were charged

Just learning how to use it. I'm a paralegal with my husband's law firm and I think this will help manage my work flow and communication with clerical staff better.

What do you like best?
I used PDFfiller to complete PDF versions of scholarship applications and it was such a time savings and so easy to work with that it was worth every penny. Since that time I have found many more features, like the verified signing, that it has become a necessary tool for both work and personal use.
What do you dislike?
Not really anything I disliked. I think the price for a personal user is a little expensive.
What problems are you solving with the product? What benefits have you realized?
Verified signatures and completing PDF documents.

I have tried a few other cloud based… I have tried a few other cloud based PDF Editors and PDFFiller is the most powerful and easiest to use. Their support has also been great when I had a billing question/issue.

est money spent Filling out forms on the daily used to be such a pain. Now it is easy! so much better than printing a page, filling it out, getting my boss to sign it, scanning it, and emailing. upload a signature, fill it out, email or save to computer. easy peasy Honestly nothing. If I HAD to complain, scrolling from page to page on a multi-page document isn't always smooth scrolling.

Love pdfFiller experience. Since day one this software provided a very intuitive interface for me. I never had a reason to call tech support or customer center. Good job Guys!!! My business has never been interrupted. Thank you for providing a very much value.

Excellent Service I did the 30 day trial period and was very satisfied with the process.I used the product for about 10 different documents within a 2 day period. I forgot about the trial period and was charged for an annual subscription and was emailed the confirmation. I went online and requested to cancel the subscription due to not needing the product and received the cancellation with 5 minutes, very satisfied.

I love not having to print forms, then fill them out and scan them. So much time, ink and paper wasted. Using PdfFiller I just upload the document, fill it out and send. Super easy.
