The best part is that it automatically "carbon copies" to other pages if they require the same information (ex: 1099 tax doc). I've used other PDF generating programs and you have to manually fill in each page. This is such a time-saver and seems like an obvious feature that would be part of any PDF program. I guess this is what makes PDFfiller a greater product than the competition!

Trumps other PDF Filling Software This is simple software to use. Easily manipulate PDF forms, enter and delete data. No more need to print, fill out, scan and send PDFs. Automates work processes for more efficiency. Sometimes if you are signed in on more than 1 computer or device you can lose your work.

Have not been able to successfully append a document more than 5 pages. That process does not appear to be very user friendly to figure out. Would love some guidance on how to do specific things with this program now that I have purchased it for a year!

Easy to edit. I had a little trouble completing the form correctly but it was my fault. I went back and made corrections easily and all seems fine.

I like the signature feature that gives a lot of options. I wish there was a better way to add information and have it look nice, but it does have the flexibility to add something anywhere, so that is nice.

I'm happy with the use of the forms, however it showed a monthy price, so I was suprised when I was charged for the entire year up front. I only needed the product for a couple tax documents.
