This is my first experience with Aatrix, and I have to say it has been a pleasant one. I would highly recommend their products and services.

I got the payroll up and running the same day I installed the software. I’ve processed all historical payrolls for the year and three new payrolls for each of my clients, and they continue to share comments of how pleased they are with their new payroll checks. Thank you for your product.
