I found it really easy to use, but all of the boxes did not have specific instructions. I struggled with boxes 16-18. Through google, I discovered that I should leave them blank.

I needed to find a template that I could use for Certified Payrolls for a small job we are working on. PDFfiller has helped me meet my deadlines. It also continues to help me as we work on this project by duplicating my existing Certified Payroll Form and updating it week by week so I do not have to retype information again. It lets me cut, copy, and paste just like I was working on a Word document; this feature saves me a lot of time.

So far it has met my needs and wants. While there has been a struggle with removing the Electronic disclosure page, their technicians and chat support are quick to respond.

User Friendly Site!
I was thrilled to find a site that would allow me to modify PDF files. Furthermore, being able to save and share the files, once I modified them was extremely helpful. Overall, I found the whole site to be very user friendly.

Better than acrobat
Love it, my go to when acrobat pdf filler isn't working
The easy operation, we can count on it to fill any PDF. Acrobat sometimes let's us down so we started using this instead
The pricing, please lower it down so we can switch to this software forever. Also a nicer desktop App would be nice

I had an occasion to need a form filler on a ***. I found PDFfiller online and tried it with a trail. It did exactly what I had wanted and it was easy to use. I guess I forgot to cancel the trial so it did go into an annual charge. I dont need a *** form filler on an ongoing basis. When I saw the annual charge on my ****** account I called immediately. I explained what happened and they immediately said they would close the account and refund my money. No hassle just very polite support person and efficient. Should I ever have an ongoing need of a *** form filler I will absolutely buy PDFfiller. It works and they believe in customer support. A rarity today.
