It is great! I would like instructions on how to save a blank form if you don't mind. I keep opening up the old form, then I have to delete data and replace it. Thank you!

What do you like best?
I like how easy it is to edit the content of a PDF. I've recently had to adjust a few documents which were not previously editable for me, and this has made it simple to keep things updated.
What do you dislike?
I would like to be able to choose the file destination when selecting Save As, rather than it defaulting to my Downloads folder.
What problems are you solving with the product? What benefits have you realized?
We've recently implemented new contracts for our accounts, and using PDFfiller has made creating them so easy. It's saved me a significant amount of time.

Poor internet connection affects how fast one can work. I commend the fact that the program saves all changes in a timely fashion.

The go-to for creating useful PDF files
This software has become a go to for pretty much every PDF file I have to create. I have used it to create forms that our midsize business uses on a daily basis. I find it to be very user friendly and a quick and easy way to get what you need. It has positively affected our costs of printing and paper, and it's good not only for our budget but for the environment too!
Customer service is not the fastest and sometimes I have a question that needs to be resolved that day. I read online that it depends on the plan you have purchased and I don't think that is the best way to treat your customers.
