• Oversee and support the monthly payroll process, ensuring information provided to payroll providers is complete and accurate and payments are made on time.
• Oversee pension administration, contributions and associated reporting requirements.
• Manage employee expense claims and company credit/debit cards, ensuring expenditure is appropriately supported, coded and approved.
