So far I absolutely love it. I figured out that I can have my clients sign things electronically through this and I swear that alone makes it worth its weight in gold!

I have an autistic son and this PDFfiller is so amazing. There is so much paperwork between social security, IHSS, ABA therapy services, and school this gives me a few extra moments to relax

What do you like best?
The interface of PDFfiller is simple and intuitive. I think that most people can sign up and start using PDFfiller without having to spend much time figuring things out. Once we load a PDF into the system, there are straightforward menu items and labels that help to fill out virtually any form from start to finish. I can save to PDF format with my filled-in information or print right from the PDFfiller website.
What do you dislike?
Anytime I post my information online, I get apprehensive about how my data is being used. Though I'm sure PDFfiller probably takes measures to keep our uploaded and saved documents secure, I just never know with all the malware and server attacks that often occur, in general.
Recommendations to others considering the product:
Some people probably don't want to hassle with putting their documents through a digitized system, but I think once you upload one form to PDFfiller, you'll see how intuitive the entire process and may possibly not print out documents to fill them out anymore.
What problems are you solving with the product? What benefits have you realized?
My handwriting is basically terrible and I often get strains when writing since I typically haven't written by hand much over the past several years. PDFfiller lets me fill out PDF documents more effortlessly and lets me align text and other objects with great precision.

This was so convenient
This was so convenient. It was quick and easy to register and begin filling out forms. This helped me out in a crunch to get my 1099 forms completed.

Easy PDF completion app
Overall from what I've used, this has been a really great way to complete and sign documents.
I liked that you can basically fill out forms but digitally. Everything is digital these days and instead of having to download and do a bunch of cumbersome steps to complete a document, you can do it straight from the app. It's much easier and cleaner.
I wish you could edit things and make changes. If you need something changed you'd have to contact the other party and have it changed then resent. But even so it's not that big a deal and it's still a great software.

PDFfiller Review
Overall, the experience is very good. I plan on using it for a very long time.
It's very easy to navigate. PDF Filler makes it easy for small business owners as myself to have the professional look when conducting business.
It's a lot of features that I don't need. This sometimes causes confusion and extra time navigating around the site.
