• Coordinate collection follow-up with project managers, clients, and company leadership
• Apply client payments and assist with accounts receivable reconciliations
• Assist with project setup and maintenance in the accounting system
• Support month-end and year-end closing procedures
• Assist with bank and credit-card reconciliations, accounts payable, financial reporting, tax filings, and FAR overhead audits
• Help improve billing, collections, and accounting processes as the company grows
