The QuatroAttendance system (QAT)), was developed to provide an attendance tracking system that would service the needs of the many Departments within a business or organization.

QuatroAttendance is a multi-user application capable of supporting hundreds of concurrent users. Its database, centrally located on a server, stores attendance history for many years. The system combines features such as: powerful editing capabilities that deal with Union and Management attendance rules; bank entitlement controls, such as, vacation, sick, lieu and floating holidays; extensive report capabilities; and friendly user interface that accommodates the roll out of the application to hundreds of remote users.

With the implementation of new sites, Quatro Group has continued to build new interfaces between QuatroAttendance and various payroll and financial systems. Currently QAT includes interfaces with SAP, Cyborg, Computron and Ceridian.

QuatroAttendance serves as a front end to any payroll system. It captures attendance data which, at the end of each pay cycle, is exported for payroll processing. QuatroAttendance also works as a "back end" system to other software packages such as Scheduling Systems and Card Swiping systems that can capture or produce attendance data with minimal editing capabilities.
