What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
When I first signed up, I only wanted a personal account. They system did not provide me with an option to choose, that I could see, between accounts. It automatically signed me up for professional and now I have to jump through a few hoops to cancel the pro and sign up for personal.

Customer support was top notch. They resolved my print issues with my form. The reason I did not give it 5 stars and would not recommend is that I Googled for a form to fill out for a US Passport. I didn't expect to find one i could fill in on line. What was not apparent was that ONLY AFTER SPENDING 30 MINUTES FILLING OUT THE FORM did I find out I had to pay $20 to print, save, fax, email or share the form. Customer service was great, but did not want to sign up for a monthly pdf service or pay $20 for 1 form.

Site could be more mobile friendly. I'm still learning but so far it has done exactly what I needed and greatly improved my ability to get the docs back I send.

What do you like best?
I like that I can fill in forms for all of my taxes, and they are saved permanently for future reference.
What do you dislike?
It is difficult to find a form that I need. I have to do a general google search, then click on the link, and fill in the form, then log into my pdf filler account. Wish it were easier to find specific forms.
Recommendations to others considering the product:
It's an excellent product for filling in forms, and creating documents.
What problems are you solving with the product? What benefits have you realized?
taxes. It has been helpful for me for the quarter and yearly tax forms I need to fill out (941, 940, W2's, W3's and 1099's).

Great PDF editor! Great! PDFfiller is easy to use, powerful, and user-friendly. It has all the features I need. I'd like to see more fonts so I can match the fonts on the PDF page.

It is not very difficult to navigate, but I do have issues with finding some of the documents I need. Plus, I feel that the pricing of basic level is too much. I am a person with a limited income and can not afford much. I need this program to help with my taxes and a few other documents, but I can not afford to pay an entire years worth!
