What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
It's a good and intuitive product. the only technical glitch is that some of the larger text boxes are shifted over to the right by a fraction of an inch and outside the printable area of most printers.

Easy to use.
It's good that we have this product cause we can just sign PDF's without printing.
Sometimes it's hard to place the 'typing icon' in the right place for filling in information or data.

CUSTOMER SERVICE THE WAY IT SHOULD BE!!
I was using pdfFiller to edit divorce documents I downloaded from the Court Clerks website. Being able to edit these documents was going to save me around $500 in attorney fees. When it was time to save and print I was directed to purchase the subscription. There are 2 options... you can pay for the whole year at once (paying $8 per month) or you can pay $20 per month and be billed each month. I accidentally authorized the whole year @$96 to be charged to my debit card. This was not my intention but I knew it was going to be such a hassle to get them to refund my money that had already cleared only to spend $20 with them. I contacted support thru the chat option anyway and found I was very wrong in my assumption. I was connected to Ray who in less than 5 minutes had refunded the difference of $76 back to my card and was inquiring if there was anything else I needed help with. This is how customer service should be and very rarely do I experience anyone who should bear the title of a customer service representative. THANK YOU RAY FOR YOUR HELP AND PDFFILLER FOR HIRING COMPETANT ENJOYABLE PEOPLE TO DEAL WITH YOUR CUSTOMERS.

I loved this software and features
I loved this software and features. However it's just out of my budget right now. It would be helpful if there was a monthly subscription or payment plan. Instead of $96 all at once there should be an option to pay a monthly fee of $8.

What do you like best?
I like that you can edit files, sign without sending through electronic envelopes and you can fax and email documents.
What do you dislike?
You cannot upload separate files and merge them into 1 pdf file within the program.
Recommendations to others considering the product:
I highly recommend using this app for your document prep and signing. It is a one stop shop to get your pdf files edited and signed.
What problems are you solving with the product? What benefits have you realized?
The benefit is the faxing capability and being able to do it from my phone.

Ny experience was good but I only have a need for the form I used maybe once a year. So I will probably be canceling my month to month once I am sure the form I needed has been accepted. It would be nice if you had an option for a subscription that was based on usage rather than on time. I might then sign up for a longer term commitment if I wasn't being charged every month but rather on my usage.
My experience with your product was that actually filling out the form was user friendly but it was a form that had a continuation sheet and figuring out how to use several continuation sheets was not intuitive and I ended up filling out several different form continuation sheet pages and then had to combine all those multiple forms into one document in order to get what I needed for submission to the court.
