Accounts Receivable (A/R) Management Monitor and manage overdue receivables with internal and external stakeholders. Apply cash receipts in SAGE Intacct and perform client account reconciliations. Project Financial Analysis Analyze and manage WIP (Work in Progress). Ensure projects are fully invoiced before closure; process closeout entries (profit/loss). Communication & Documentation Manage shared inboxes for invoicing, timesheets, and AR inquiries. Support audits, organize digital files, and help develop document archiving policy.
