I have found it useful to complete a myriad of forms required for our charity administration electronically - rather than having to print, complete, scan etc.

Great app! Use it on my phone which is great and handy in situations where documents need to be signed and done in a hurry. Only down fall is mailing documents sometimes gets sent to spam or junk mail. So tell your recipient to check their spam box just incase.

As a freelancer I use PDF Filler to complete W9 forms - it's great!
PDF Filler is simple, easy to use, and creates professional documents that are easily accepted by employers and large corporations.
The exporting workflow is a little confusing - at least for their IRS W9 Form. Instead of just pressing a button to save the file to my phone I had to email it to myself in order to obtain it. This may have just been my ignorance, however. All in all, PDF Filler is a great help!

The frequently used function buttons are placed on a easy-to-find position. The interface is neat and clear which is user-friendly. It is easy and simple to use.

It is useful. Only thing I would like is for it to figure out what font I had on the document BEFORE I edit it. I have contract templates that I use that I have to edit sometimes and finding the font that will match that size and actual type is very difficult. i usually end up just dealing with whichever one I find. If there is a way to do that, please let me know via email.
