About the Client
Our client builds advanced software and hardware for defense and national security customers, with the goal of helping to protect the safety and freedom of people around the world. They are seeking a detail-driven Revenue Associate who is energized by getting their work invoiced accurately, paid on time, and their government customer relationships running smoothly. Client name disclosed upon mutual interest.
About the Role
We are seeking a self-starter and team player to contribute to our Growth team. This individual will own the end-to-end government billing process, from invoice preparation and submission through accounts receivable and collections, ensuring the company is paid accurately and on time across a complex portfolio of DoD, federal civilian, foreign/FMS, and state and local government customers. The ideal candidate brings deep, hands-on expertise with Wide Area Workflow (WAWF) and the broader Procurement Integrated Enterprise Environment (PIEE), understands how the organizations that drive government payment (DLA, the DFAS financial services center, and DCMA) interact, and can navigate the documentation and compliance requirements of government invoicing with minimal guidance. They are precise, organized, proactive about resolving rejections and payment delays, and thrive in a fast-paced, high-growth, and highly fluid environment.
Responsibilities
Prepare, validate, and submit accurate government invoices and receiving reports through Wide Area Workflow (WAWF)/PIEE and other required customer portals, ensuring each submission aligns with contract terms, CLIN/ACRN structure, and applicable payment clauses (e.g., DFARS 252.232-7003 and 252.232-7006).
Own the full billing lifecycle across DoD, federal civilian, foreign/FMS, and state and local customers, adapting to each customer's system: WAWF/PIEE for DoD and Treasury's Invoice Processing Platform (IPP) for federal civilian agencies, plus FMS and state and local billing requirements.
Serve as the company's subject-matter expert on the organizations and systems that drive government payment: the Defense Logistics Agency (DLA, which administers PIEE/WAWF and the help desk), the DFAS financial services center and its entitlement and payment systems (MOCAS, One Pay), and the Defense Contract Management Agency (DCMA) for inspection and acceptance of DD-250 receiving reports.
Monitor invoice and payment status through myInvoice and Electronic Document Access (EDA), proactively researching and resolving rejections, recalls, and payment delays before they affect cash flow.
Own accounts receivable end to end: maintain the AR aging, apply cash receipts, reconcile billed amounts to the general ledger, and lead collections follow-up with government payment offices and prime contractors.
Maintain accurate registration and routing data, including SAM.gov, CAGE codes, EFT/banking details, and PIEE routing/DoDAAC information, so invoices route correctly and pay on first submission.
Partner with program management, contracts, and accounting to confirm funding availability, CLIN/ACRN status, and billing milestones, and to support timely contract closeout.
Ensure compliance with the Prompt Payment Act and contract-specific billing requirements, minimizing interest penalties and rejected submissions.
Support month-end close on billing and AR matters, including unbilled and work-in-process (WIP) analysis and billing-to-revenue reconciliations.
Build, document, and continuously improve standardized, repeatable billing procedures, identifying opportunities to streamline and automate the invoicing workflow.
Maintain audit-ready billing records and support DCAA, internal, and customer audits with accurate, well-organized documentation.

Experience invoicing a broad range of government customers, including DoD, federal civilian agencies (including Treasury's IPP), foreign governments/FMS, and state and local entities.
Strong command of government billing compliance, including FAR/DFARS payment clauses, the Prompt Payment Act, DD-250 receiving reports, and CLIN/ACRN funding structures.

Exceptional attention to detail and organization, with the ability to manage a high volume of invoices and deadlines simultaneously and with minimal supervision.
