I love this program, it is very helpful. However, I would like to see more PDF editing tools available, so I can do things visually, such as cropping, re-sizing, etc...

I really appreciated the customizable aspects of your software -- it made all the difference to my forms! The only thing that I would've liked more is if upon searching for the form, you could filter and guarantee that its the most up to date form the gov has issued. Thank you

More than what it says on the tin
I am forever annotating drawings for the Home Improvements I offer my customers. We can assume that people understand drawings but most don't. The extra points I can make using arrows and text make it easier for my customers to understand and I know it helps me win business.
The software is easy to learn (I'm old so my patience with new programmes is not good). It has never frustrated me to use.
I can't think of anything about the software that I don't like

It gives me a lot of options to pdf editing
It gives me a lot of options to pdf works that I did not find somewhere else, and even when I cannot readily pay for the service, I was given a trial with no gimmicks attached

I used it for my rental application and lease. The app at times was very slow to open. that's why I rated it a 4/5. Other then that it was easy to use.

IT IS VERY CONVENIENT WHEN WE NEED PRIOR YEAR TAX FORMS AT OUR FINGER TIPS. AS FOR ADMINISTRATIVE TEMPLATES, IT IS VERY RESOURCEFUL AND ABLE TO COMMUNICATE THROUGH EMAIL, FAX, ETC. THANK YOU.

Chatted online to cancel and refund $96 that I was charged and I got a pretty friendly guy named Peter! He was sweet and fast! If I needed this particular application again, I would definitely reuse them!!!
2020-05-03
This has by far been the best document application ever I just wish it wasnt so expensive. If it was more of a value I would pay for it monthly. But I love it
