The Accounts Receivable and Contracts Compliance Specialist supports CRS’s financial operations with a primary focus on government contract invoicing, billing accuracy, contract compliance, financial documentation, and audit readiness.
This role works closely with Finance, Contracts, Operations, Payroll, and Program Management to ensure invoices, supporting documentation, labor allocations, contract deliverables, and billing records are accurate, timely, and aligned with applicable contract requirements.
The ideal candidate has strong financial analysis skills, a working knowledge of government contracting requirements, and the ability to review contract data, identify discrepancies, support billing packages, and maintain organized records for internal review, client submission, and audit support. While this position requires a solid understanding of accounting principles, the primary emphasis is on contract compliance, invoice validation, reporting, and government contract financial support rather than hands-on daily accounting operations.
