I needed to find a template that I could use for Certified Payrolls for a small job we are working on. PDFfiller has helped me meet my deadlines. It also continues to help me as we work on this project by duplicating my existing Certified Payroll Form and updating it week by week so I do not have to retype information again. It lets me cut, copy, and paste just like I was working on a Word document; this feature saves me a lot of time.

This program really provides me the opportunity to create the forms and fillable documents that can help speed up my report filling.
I enjoy the different ways to sign and initial different documents that otherwise could not be sent back electronically without several steps. I also have created templates and forms for consistent reports and forms I will be using to help speed up my entries. Thank you I do enjoy the program But I only know a little about it. I wish there was a little more user friendly tutorials.

What do you like best?
The ability to easily upload various documents and manipulate as needed.
