OSUP implements and maintains requirements for the statewide payroll system (LaGov HCM) which pays approximately 51,000 state employees each payroll cycle encompassing a liability of about $61 million. This system centralizes payroll functions within the Division of Administration which result in the availability of timely, uniform payroll information. It accommodates greater efficiency in the payment of state employees, the accounting for payroll liabilities, and the transfer of money between funds while facilitating centralized cash management.

The OSUP staff coordinates efforts to ensure accurate and timely payments to vendors, to expedite payroll payable liquidation, to establish, maintain and monitor all statewide actions associated with garnished wages, and to assist agency personnel with all phases of the payroll process. OSUP issues directives and policies through the distribution of OSUP Memoranda.
