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 really works My over all experience was pretty good I really like this software and would reccomend it to everyone it is definitely my top choice. I liked the fact that you could take virtually any document and fill in the spaces with the information of your own. It really makes things a lot easier I didnt like how you couldn't delete words that were already there I wish it was all in one app instead of having to download 3 or 4 different apps to get what I want done accomplished

A very easy to use program A very easy to use program, though you are forced to sign up for free trial if you want to print any documents.It did what I required, so cant complain. Just would prefer it to notify of unable to print unless joined up for 30 day trial before I spent 4 hours working on translation document.
Macgyver
What do you like best? How easy it is to use, the signature function too. What do you dislike? History saves only one document and can't change it. Recommendations to others considering the product: It's great, so don't hesitate What problems are you solving with the product? What benefits have you realized? Don't need a printer and scanner to fill out documents
Lyne Daoust
If you have forms to fill out electronically, this is the website to use. It is simple even for those not great with tech! Customer service is also very honest and helpful as far as billing, etc.
