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.

I have used it almost every day for over a week to fill out forms. I find it to be a bit awkward at times but I'm getting better at finding my way around. I will continue to use it.

This morning my subscription to PdfFiller was automatically renewed. Once I realized it, I notified the company to cancel my subscription and to provide a refund. Within a short time, I received a response confirming that the subscription was canceled and that the charge was reversed. I would definitely recommend this company and would use them again if I had a need.TL
