Learning how to use pdffiller
I'm just learning how to use pdffiller, and it's very easy to pick up. Of course, I've had to ask their tech support for help, and later discovered the answers were simple and in my face! It's all there. Tech support is great. They get back to you asap with very friendly and pertinent info.
I especially like the fact that you can create paperless docs and set them up to reuse them as templates. I think it's a great product!

I mislead them on my intentions for the service level that I required. Once I brought it to their attention, I answered 3 questions; and the matter was immediately resolved. Outstanding customer service comms. !!!

user friendly and practical, what would really differentiate would be the possibility to use the app when offline and automatic synchronization once online.

I love that pdfFiller.com has a vast selection to search through, although it can be frustrating to find what you are looking for because even when you change the search information, the same ones pull right back up. The price is fair if you use it daily or at least 3 times a week, which I don't but I use it frequently enough since there is no cheaper option than the monthly rate.
