I like the idea that I can go back and fill in the parts of a report that I couldn't finish in one sitting. This will a big help to me in my newly appointed position.

Very good. Easy to use. Perfect "side dish" for users who don't need full PDF Writer needs. Has just been saving me hours in handwriting out form information

It's pretty good, but some repeat items don't load, and a couple times it would not let me add a 3rd line in a box. It would be nice if columns of numbers could add up.

Editing pdfs without the need to convert them What i like the most about this software is the fact that when i have to edit a pdf wher i lost my source document i dont have to convert it in order to edit it, i can just simply use pdf filler editing functions and that's it. Took some getting used to as it, also in some cases is complicated to get the text in the place i selected to put it

CUSTOMER SERVICE THE WAY IT SHOULD BE!! I was using pdfFiller to edit divorce documents I downloaded from the Court Clerks website. Being able to edit these documents was going to save me around $500 in attorney fees. When it was time to save and print I was directed to purchase the subscription. There are 2 options... you can pay for the whole year at once (paying $8 per month) or you can pay $20 per month and be billed each month. I accidentally authorized the whole year @$96 to be charged to my debit card. This was not my intention but I knew it was going to be such a hassle to get them to refund my money that had already cleared only to spend $20 with them. I contacted support thru the chat option anyway and found I was very wrong in my assumption. I was connected to Ray who in less than 5 minutes had refunded the difference of $76 back to my card and was inquiring if there was anything else I needed help with. This is how customer service should be and very rarely do I experience anyone who should bear the title of a customer service representative. THANK YOU RAY FOR YOUR HELP AND PDFFILLER FOR HIRING COMPETANT ENJOYABLE PEOPLE TO DEAL WITH YOUR CUSTOMERS.

My only use is to help my 14 year-old grandson with his Eagle Scout Service Project report. I'm retired and have no further use for the program beyond next year when he has completed his Project.
