Zellis & Unipay
Unipay is a sophisticated and flexible computer payroll system for very large employers, developed on the IBM z platform running under zOS/VM with operating systems VSE, MVS and IMS, with on-line CICS available in VSE and MVS.
It provides extensive formula and reporting functionality for on premise installations.

The principles
Since the Unipay system was first introduced in 1964, continuous research, development and field experience drawn from countless user installations have made significant contributions to the advancement of its technology.
As a result, Unipay has been developed into a highly sophisticated system which has seen great success in uses across the public and private sectors.
The adaptability and flexibility of the Unipay system enables each user to define specific features and processing requirements at the same time, providing a very high level of efficiency and economy in operation.
There are two distinct versions of Unipay available. The structure in which each system runs can be tailored to each customer’s requirements. Employee data can be input online or in batch mode, and online screens can be designed to your own specifications.
