This is a great programme This is a great programme - but as an individual, probably not quite what I wanted as it is a bit expensive for the odd document.

What do you like best? Definitely needed for any business that handles a lot of paperwork. We use it on almost a daily basis to fix or change a document that may have been mis-written and it is very easy to do this with PDFfiller. The ease of use is fantastic, we recommend it to everyone with a business. What do you dislike? I wish there were more options to match the color of the page when you erase something. And more font options to match the current font on a document. I also wish it was easy to upload multiple documents to create one solid PDF. That is one thing that I would like to see in any new updates. Also the system could possibly use a style refresh. It does seem a tad outdated looking, but that does not affect its usefulness. Recommendations to others considering the product: Just use it! It is worth every penny if you need to edit any documents What problems are you solving with the product? What benefits have you realized? Easily fixing business documents. Very smooth and easy to use. We are able to use this system to edit documents on a daily basis. We love that when you erase something you can just type right where you just erased so it matches the lines perfectly. It also makes it easy to fix boxes and add signature lines. It is also very smooth to upload documents and edit them. Definitely appreciate this system very much and we would recommend it to everyone we know.
