Beyond payroll, the Staff Accountant supports month-end close through journal entries and account reconciliations in SAP, and serves as backup for Accounts Payable, including OCR invoice processing and vendor payment execution when coverage is needed.

• Apply OT and double-time rules, holiday/weekend premiums, shift differentials, and call-in/reporting pay as applicable to a union and shift-premium environment.
• Validate payroll outcomes using ADP registers, time exception reports, and earnings code reporting before finalizing each cycle.

• Prepare and post journal entries in SAP with appropriate supporting documentation and review trail.
• Independently reconcile assigned accounts (accrued liabilities, prepaid/expense accruals) and clearly explain reconciling items: what they are, why they exist, and when they'll clear.
• Support month-end and year-end close activities, including tie-outs, variance explanations, roll-forwards, and audit schedule support.
• Build and maintain standard recurring entries with clear logic, consistent timing, proper reversals, and control documentation.
• Process weekly freight invoices.
