Great Value! A Must Have!
PDF Filler is one software that's worth so much more than what I paid for. I work in 3 different industries- Staffing, Construction and Real Estate and this software has become a necessity in everyday document preparation. It saves so much time and money. No need to subscribe to expensive Adobe editing software. Every time I show how this software works to friends and colleagues, they are amazed. I wish I had known about PDF Filler long time ago. Thank you!
Ease of use and integration with Sign Now.
The dashboard could use a bit more organization.

What do you like best?
I work remotely, don't have a staff or colleagues at my finger tips and find myself in constant need of sending out advertising agreements in an efficient manner. I have the ability with PDF filler to quickly revise and add to routine contracts efficiently.

The process, of saving and downloading revisions sometimes requires extra clicks and can be simplified.
Recommendations to others considering the product:

It is difficult to find the exact years…
It is difficult to find the exact years form. For instance, I searched for 2019 1040 SE and I got a lot of 2014 forms. I had to over search for the correct form.
