I AM ONLY HALF WAY DONE BUT SO FAR VERY EASY,HOWEVER I FIND THE BILLING OPTIONS DECEPTIVE, ALSO LIVE CHAT SUGGESTED A SOLUTION BUT DIDN'T MENTION IT REQUIRED AN UPGRADE!

It was difficult for me (86 years old and somewhat "ok" with Windows 10) to figure how to send the document to my partners vie email for their markup, etc.

i thought it was a free program but I needed to pay for it when I tried to print the document, it required payment. I did so, but then complained to the company and they fully refunded my money

All-in-one tool that ultimately expedites the process of filling out and scanning forms.

Nothing in particular; fixed one-time pricing would be preferable over subscriptions though.
What problems are you solving with the product? What benefits have you realized?
Reducing the amount of physical computer hardware in the office (scanners, printers) through the use of software such as PDFfiller.

PDFfiller is a great tool to use for editing and templates PDFfiller allows me to utilize the same forms frequently. As a result, templates or refillable forms ensure document preparation is quicker and more efficient. Cloud security, ability to easily create templates for commonly used forms, flatten forms after fields filled in when saving to hard drive, in PDFFiller form remains in tact and is editable for reuse, and menu set-up. I wish PDFfiller would add the ability to add pages to a documents and allow downloading of templates created. Currently, in personal account, PDFfiller allows emailing to recipient to update information in fields, but doesn't allow me to download my template to my hard drive.

Very easy to use I am excited to learn all the features the software has to offer. I am so happy i can take current PDF files and turn them into filliable files. This has been very helpful as i started this position and can't always find fillable files.

Easy & simple to use! Perfect for e-signing docs. Navigating the documents is easy & doesn't take you into weird places of the doc that don't need attention. I don't see any improvements that need to be made, I really like this product.

pdfFiller.com gave me faith in online… pdfFiller.com gave me faith in online companies. I have no idea what I was trying to accomplish, but had signed up for a 30 day trial. I never used the program, just must have been sleep working. Anyhow, I was so surprised when I got the notification that I had just bought a year subscription. I was beating myself up and trying to figure out how I could be so unaware. I first tried to call. The phone was endlessly busy, I thought wow I just lost $122 (I paid in Canadian funds). Anyhow, I thought I may as well try sending an email. I could not believe it!!!! The response was almost immediate. Max, took care of everything. He issued a refund, and let me know he had cancelled any future subscription. I was in absolute shock. If I had a need for pdfFiller, in that moment, I would have signed up for years. THANK YOU for being accommodating and obviously trustworthy. Again, you have given me a bit of hope for humanity.
