I was in a hurry to get a commercial invoice to a broker, all went well until I tried to email the document. I'm 64 years old, so not the brightest when it comes to computer stuff, but it was really confusing at that point.

I've only just started using it, but so far; I am loving it. It's easy to use, and very useful with my work. I'm an RN and I work as an independent nurse, so having this program is so nice for my plans of care, and sending them to the physician to get signed is easy peasy! Thank you.

Intuitive and easy to use Easily and quickly fill pdfs with this simple software, just be aware there is no free option other than a 30-day trial. This software is really straightforward and easy to use. I find it intuitive and am able to edit pdfs quickly and painlessly. Adding a signature is really easy as well. I did the free trial of this software and even though I was impressed, I didn't end up purchasing the monthly subscription due to my needs. There are options out there that are free, although they're definitely inferior in terms of functionality and user interface. So I think the cost (even though it is reasonable) ended up being not worth it for me specifically in the end. Other than that, I had no problems with the software and would recommend it to someone who uses pdf software frequently.

An excellent company with mind-numbingly awesome customer service. I expected an automated response and a week or more wait to resolve an accounting problem, what I experienced was not only a response but total problem resolution in less than and hour. Unfortunately I dont have need for their services at the moment because these guys are just the type of business I want to do business with and I am positive you will too. Thank you **** and ***** for your unbelievable attention to detail and rapid results.
