What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
I really enjoy PDF filler and the multiple optiond that it allows. However I think that it would probably beat out "docusign" if the monthly payment was a bit more economical such as9.99. However, for the most part it is a pretty decent service.

I lost you.... I found you then I tried to get a refund unable to figure out your site.... I tried for months you can see it was never used, CHASE tried to reach you...long story you had popped up I never noticed the name of this when I crashed that was it... I have all of the old emails off a hard drive on a back up device... I might re sign but 30 days is not worth losing 72.00 I dont use this much most of my forms are already loaded not sure yet I have become further disabled trying to recover back then your chat did not work nothing....

The UI is outstanding and very effortless. Very impressed.
My only issue was with advanced features. Would have liked to know ahead of time that they were additional fee. Everything looks included and don't like being told something cost money after the fact. Second, when telling me I had to upgrade to get additional feature, it should show the difference between what I am paying verses the new amount. I was on personal plan ($6) but to get the features I needed it was ($10). It said it was $10 for advanced plan but I didn't know if that meant $10 MORE than I was already paying. I had to open site in incognito mode, look at plans to figure it out... not fun.
Lastly, I was trying to send 2 separate PDFs as one doc. It took me a while to figure out where Merge was. I didn't understand why all the options under Actions were greyed out. That was very frustrating and should be improved.

IT HAS SOME TREAKY THINGS AND AT SOME POINT IF IT IS NOT PRINTED OR SAVE BEFORE HAND, YOU HAVE TO REPEAT THE WORK ALREADY DONE. IN THIS CASE, HAS BEEN A LITTLE UNPLEASANT SITUATION AND WASTE OF TIME, IT SHOULD HAVE SOME AUTOMATIC SAVING, AS IT OCCURS IN WORD.

Everything has been great, with the exception that it takes a while to open up the documents on mybox. There should be a feature for ''QUICKVIEW" of the document you want to open.

This app has been a lifesaver. I have recently started a position as an Administrative Assistant and the abilities within this program make my job hassle-free. It makes filling in PDFs and requesting e-signatures as efficient as possible.

What do you like best?
I like how easy it is to edit the content of a PDF. I've recently had to adjust a few documents which were not previously editable for me, and this has made it simple to keep things updated.
What do you dislike?
I would like to be able to choose the file destination when selecting Save As, rather than it defaulting to my Downloads folder.
What problems are you solving with the product? What benefits have you realized?
We've recently implemented new contracts for our accounts, and using PDFfiller has made creating them so easy. It's saved me a significant amount of time.

What do you like best?
I use Quickbooks and have to send out 1099NT which is not a capability in Quickbooks. 1099 forms must be scannable and I can purchase the printed forms and fill it out on PDFfiller. I can then print on the scannable forms and they are perfectly aligned. Saves time and money. Also, I like the fact that I can create a template so I don't have to re-type the same company information, tax numbers, etc. The product is easy to use.
What do you dislike?
I don't really dislike anything about PDFfiller. Other than maybe the fact that I probably don't use it enough to offset the cost.
Recommendations to others considering the product:
Easy to use - I intended to use for a month and then cancel, but I ended up keeping it.
What problems are you solving with the product? What benefits have you realized?
I mostly use for 1099NT's as mentioned above. I really need to explore!

The form was free
The form was free, really free and didn't require me to pay to download my document as other sites do. It was easy to use with instructions provided. I loved the check mark option.
