It is great to be able to find government forms I need for my business and able to complete them in such a short time! Going through other services, this proves to be costly (especially at tax time) and the yearly fee I pay is minimal and well worth it!
Channon S
I have been working with PDF filler for a couple of months now and am very satisfied with both the ease of use and the results. I find PDF filler to be an excellent substitute for other products which are much more expensive.
Terry D. S
It is somewhat confusing at first, but after learning the program it is very helpful and convenient to use! I enjoy all of the different options regarding the tools to fill out a PDF, for me it was a rental application for an apartment that i needed to fill out. The one thing I did not like is that after i had filled out my entire application via the pdffiller app, i could not e-mail the pdf until i paid for a plan. Somewhat disappointing, but regarding the program it is a good one.
Joshua Stephen E
you have forms that are not updated. however, for a particular project- i had to recreate forms filed in 2010. you were the ONLY place, company, resource that had these non-updated forms!! yay!!
crystal k
Works well, but not sure why you create a page that cannot be scanned and sent to the IRS on the first part of the form. If this is not legal or usable why have it?
Anonymous Customer
But the important thing is they indicate that it is free to use online, but they demand that we subscribe to make a charge, then we do not have the link to cancel
M Santiago
Helpful for Digital Signature Overall the PDF filler is amazing and free! These days, a lot of people don't have printers and scanners. Also, a lot of us are working from home. This software makes it possible to sign documents without printing and scanning. My least favorite thing is that you have to create an account to save your document. It would be nice to not have to provide my email to save the document.
Courtney T.
I needed to use the service for an application I needed to use the service for an application! It was only needed once. The day I was going to cancel it due to no longer needing the service the money had already come out of my account. They immediately refunded it and even offered a discount if I wanted to continue using it. I highly recommend it was an easy to use service with many benefits packed in.
Kayden Renee
I used this one time for squares for a fundraiser and was looking forward to continuing using this service needed for a side job; however, this side job fell through. I thought I had cancelled on March 2, but must have not submitted something. I was charged today. If I could be refunded I would really appreciate it.
