it does important essential legal functions in ways that work but are somewhat visually disorienting and that are provided through a user-insensitive, extortive pricing model.
The fact that PayPal has removed you from their approved subscription list may be entirely technical but it does not inspire confidence.

The best part is that it automatically "carbon copies" to other pages if they require the same information (ex: 1099 tax doc). I've used other PDF generating programs and you have to manually fill in each page. This is such a time-saver and seems like an obvious feature that would be part of any PDF program. I guess this is what makes PDFfiller a greater product than the competition!

The only thing I really had a problem with is that I completed what I thought was a "free" form and then had to sign up for a free trial. The actual program is very useful and helpful and relatively easy to navigate through.

Organize my PDF nicely
It was smooth and easy and quick. Thank you
PDF filler is one of the best pdf converters. It has many usages. From storage, file conversion, editing and so on.
Nothing, thus I like the app in general. I can do a lot for my pdf related files.

Appreciate to keep the pricing say within $10 and max of say 10 docs instead of $20 per month. No contract please

There are some glitches
There are some glitches, like if you type to fast it will double or triple the word your typing. But other than that it's great.
