Helpful Tool
I had been trying to send off some release forms and was crunched for time so I signed up for PDFFiller's free trial. In the end, I wasn't able to use their software without a purchase, but it made me almost wish I had paid the money.
I like that I can sign any document electronically. It definitely saves time and printing costs. It cuts out about 2 extra steps: printing and scanning. This is helpful for documents that need signatures such as release forms, etc.
I didn't like how much I had to pay in order to use my e-signed pdf. I don't use the software often enough to make it worth the price.
However, if I worked regularly with documents that needed to be signed this software would be the very best solution.

I filled out forms before purchasing app and thought it was saved. After I purchased the app I could not find my document. I texed with a customer service rep, he was no help and quit the communication.

I was able to find any form that I…
I was able to find any form that I needed to fill out. PdFiller was instrumental in helping me fill out additional tax forms needed to file my taxes. All the forms were there already! There's even away to have your documents sent/mailed to the intended party! I wish there was a way I could have a subscription for a much lower amount that's based on my usage. Right now the price point is decent for a person that uses it frequently like multiple times a day.
