- Record payroll journal entries and support reconciliation of payroll register data (Rippling/Paycom) to the general ledger, including accruals across pay periods.

- Support month-end and year-end close processes, including journal entries, account analysis, and preparation of supporting schedules.
- Assist with budget-to-actual reporting by compiling and organizing monthly data from facility-level workbooks.
