i was under the impression that your company made a pdf document fillable for us to put on our web site or facebook page. evidently my form will only be available for 30 days. kind of a rip off in my opinion.

Good service and glad that it is available to use. A lot better than printing out forms and filling them out by hand. I highly recommend PDFfiller.

Handy service, wish it was a little cheaper and a little more intuitive. It should be easy to fill in a form over and over but there is no save as, so you end up redoing your work a lot as it saves over it.

The software could use some updating. It is not the easiest to edit the document. The app also kept crashing on me and I had to start all over again. It was very frustrating.

The tool was very efficient for my work… The tool was very efficient for my work related updates as well. I was able to store my documents and update it as per necessary. I was looking for a better way to see my documents on the dashboard like a folder view.

cost per document option I would like it if you could have a price per document option. I very rarely need this app but when I do, it is very nice to have.I can't justify a monthly subscription but would pay $3 to $5/document. to use this app.
