It's incredibly easy to use! I *love* that I don't have to print this stuff out and fill it in by hand anymore. And making edits to what I do is super easy too! I'm so glad I found this website!

My only use is to help my 14 year-old grandson with his Eagle Scout Service Project report.
I'm retired and have no further use for the program beyond next year when he has completed his Project.

Reasonable but not fantastic
Pretty decent, I'm not sure it's the best PDF software available, but it's not bad and can complete most tasks you'd ask of it.
The software works for the most part well and allows the signing and creation of forms, handy for mild administrative use.
Support seems limited to live chat only, which is a bit of pain if something goes wrong. It could also do with a mobile app which I don't believe there is currently.

I love the product just don't have the need to justify a full subscription. I enjoyed the trial period and had great Customer Service when needed. Very prompt with replies. I would recommend this product.

I tried the software and then cancelled…
I tried the software and then cancelled it. For me it was too challenging to use. However they still charged my account for a year up front. I didn't authorize that. I called and requested a refund and they gave one right away, so they said. It was just today I requested a refund so I will check my account in a few days to see if they actually sent it. If you don't see a complaint from me here on Trust Pilot then PDFFiller honored my request. My name is MarioV.
