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.

Amazing customer service, very fast response time
I was on trial with pdfFiller and it was really amazing. The best PDF filling software I've ever found. I even used the trial, forgot when it ended and then got charged. BUT I managed to get a refund after explaining my situation. These people are awesome. I definitely will be back when I have enough money.

Easy to replace text, add images, send for signatures, etc.

The organization of "my documents" is not very intuitive. Also wish there was an option to open the document without downloading.
What problems are you solving with the product? What benefits have you realized?
I have been able to complete team documents with multiple signers who are all in remote locations. I am able to rearrange and create valuable reports each month.

Great tool to simply fill out PDF
Nothing super fancy but a stable, well purposed PDF editor that has easy access to upload and download PDFs.
Easy to upload and download PDFs for simple editing tasks. Whether wanting to fill out with text or signatures, very simple to edit freely on a PDF.
A lot of competitors that are web based make this another run of the mill PDF editor. Nothing super fancy.

Fairly easy to use
Fairly easy to use. Would like to combine 2 or more docs into one file so I can fax as a group. I'm sure that's an option; but haven't found it yet...still new at this.
