Building software tools and payroll APIs for award‑winning software applications since 1984.

In 1984, Symmetry Software sold one product and was run solely by software pioneer, Tom Reahard. Today, Reahard has transformed the company into a leader in payroll-related technology applications that simplify the payroll process from start to finish. Over 30 years of creating and innovating in the software and technology landscape positioned Symmetry Software into such a role. Under the guidance of Reahard, the Symmetry Software team diligently continues to provide leading-edge and regulatory compliant products.
