I am happy with PDF filler. It has been such a great help with my court docs. I am constantly having to complete docs and with PDF filler all the information is saved and I only have to edit and save for next court hearing. PDF filler has saved me so much time and headaches. Thank you!

I own a few franchise restaurants and have to use this product about once a week and it makes my time with documents way faster and easier. I don't have to download a document, scan it, sign it, and then rescan it and then send it. I can do it all electronically thanks the PDFfiller.

What do you like best?
The best features are (1) the ability to easily import and that it converts with accuracy and (2) the ability to manipulate doc - more specifically merge, edit, copy, etc.
What do you dislike?
The only feature that does not seem intuitive at times is the folder structure and how the files are organized. When editing a doc it will always move a doc to the top because it is the most recently viewed or edited doc - but this sometimes makes it confusing. Similar to Outlook, it would be nice to have easier drag and drop feature for organizing the docs.
Recommendations to others considering the product:
This is a quick out of the box product, overall very intuitive and easy to use.
What problems are you solving with the product? What benefits have you realized?
Able to import and edit docs as well as having them signed online.

Tons of functionality for a great price. Excellent customer response time.
Feedback: when using the "home"/"end" keyboard buttons, it immediately takes you to the top/bottom of the form instead of beginning/end of the text box you are editing. Just an unintuitive and weird feature.
Also, it would be great if there was a way to save LinkToFill settings so that they can be applied across other documents.
Overall really happy with this product!
