What our customers say about pdfFiller

Just concerned that e-mail was sent with form.
I did not want to subscribe to PDFfiller as I was trying to ensure that a form for Strikenet had been sent and received. I did not authorize $119.88 USD to be charged to my Visa. What I did approve was $170.00 for a Strikenet report. First attempt at trying to submit form as Strikenet taken over my Weather Fusion. Would request a refund of $119.88 USD as I do not intend on using PDFfiller, or please inform me on how I can get a refund. Thank You.

I can believe how simply this was and how long I fought trying to make other pdf forms work before this.. well worth the money. and I didnt even have a need to take full advantage of all the features. highly recommend and thank you

Works well but continues to have security issues in connecting with my Google Drive account. Each time I open a PDF in Drive using the PDFFiller App, I get an Unsafe warning. Please clear this problem up. I don't have the time or energy to do your survey right now, perhaps in the future.

Fill in the Blank
Love what this has done for making my job so much easier at a very reasonable rate.
For my business this was and is the best tool I have for putting together insurance reports. Build or scan in a template and fill in the blanks when you need to send a report out. BAHM! DONE!
Probably something I have not spent enough time to figure out yet but as of now each time I fill in a blank template it auto saves it so my original always has to be cleared before new entry.

I like having this resource as an option.
I like that it offers a clean, crisp look for documents.
The forms or finished forms look very neat when they are typed. It seems like a great option for persons to use when their handwriting is not legible.
The words do not stay within the lines. I used the software recently and the office manager had to retype the form because the words did not fit.

A great online software
A great online software, easily linkable with Google Drive. You can modify as far as you want your documents, make signature and so much modifications.
Really useful and safe for any documents.

As opposed to quite a handful of our competitors, we respect your time and want you to become as productive as you can. Produce templates for the most regularly used documents to prevent retyping information, fill out as much as 1,000 uniform documents at a time, or extract information from forms in bulk.
Extensive library of forms and templates

Very simple e-signing and tax reporting
Thanks to the integrated signNow functionality, you can e-sign documents on the go, gather signatures from multiple individuals, track the signing progress of a document, set a signing order, and much more.
Security and plenty of storage space
We care about the security of your assets and think that storage limits shouldn't distract you out of your work. That’s why pdfFiller allows you to keep your documents protected within the cloud with unlimited storage. On top of that, you’ll be able to protect sensitive data with two-factor authentication and passwords.
