This is my second time using this program & I don't recall having to line up the cursor each time where I wished to type. It would be easier to tab between fields.

I use PDFFiller for our trucking company Bills of Lading and Log Sheets. I absolutely love it! My paperwork looks so much more professional and the more I use it the more I like it.

Working Experience With PdfFiller i am using this software for about 8 to 9 months. the best thing i found in this software was its feature to send the file online without makuing sure to save first and then send. other feature i liked the most is that i can easily edit the pdf format by using this software. it is really very favorable feature to avoid the conversing to word file for editing. in my opinion, there must be improvement with the font size of editing text to make it more compatible with text. i face a problem to make the ediding in the same font size . Althorugh, it is same as that of text but it seams different. it makes the file less professional.

Used the product a few times (PDF editor) and really liked it but disn't use it enough to warrant purchase. I forgot to cancel the free trial and was charged the annual fee a few weeks later. The company immediately refunded me when I requested it, and did so without question or issue.

Quick sign up, User friendly for beginners and love the functionality!! What made my experience great is that it was simple and easy to use, I had only used docusign once before and decided to try pdfFiller for some court papers that needed electronically signed immediately. It is super user friendly. Great pricing after the 30 day free trial. But my favorite part is the set up and how many different things you can easily do!!!!
