Defense Finance and Accounting Service (DFAS)
The Defense Finance and Accounting Service is a Department of Defense agency responsible for financial management and accounting services across the DoD. DFAS serves as the central payment and accounting office for defense operations, including contractor payments, military payroll, civilian payroll, and financial reporting.
What Is DFAS?
Established in 1991, DFAS was created to consolidate finance and accounting operations across the military services.
DFAS is responsible for processing contractor payments, managing military and civilian payroll, maintaining DoD accounting records, preparing financial statements, managing debt and collections, and supporting financial audits.
DFAS ensures that DoD funds are properly accounted for and disbursed according to federal law.
Core Functions of DFAS
Contractor Payment Processing: DFAS processes invoices submitted under DoD contracts. This includes reviewing payment requests, verifying contract funding, issuing electronic funds transfers (EFTs), and applying withholds when required. Contractors typically submit invoices through systems such as Wide Area Workflow (WAWF) or other DoD payment portals.
Accounting and Financial Reporting: DFAS maintains the official accounting records for the DoD. It prepares financial statements in compliance with the Federal Acquisition Regulation, federal financial management laws, and government-wide accounting standards. DFAS supports DoD audit readiness and financial transparency.
Military and Civilian Payroll: DFAS manages active-duty military pay, Reserve and National Guard pay, civilian employee payroll, and travel reimbursements. While contractors do not receive payroll through DFAS, they interact with DFAS for contract payments.
Debt and Collections: DFAS is responsible for identifying overpayments, managing contractor debt, and collecting funds owed to the DoD. If a contractor is overpaid or subject to disallowed costs, DFAS may initiate collection action.
Why DFAS Matters in Government Contracting
DFAS plays a critical operational role in ensuring contractors are paid accurately, funds are disbursed according to contract terms, financial compliance requirements are enforced, and improper payments are identified and corrected.
Without DFAS, the financial backbone of defense contracting would not function.
Implications for Contractors
Contractors working with the DoD must submit accurate invoices, follow contract billing instructions, ensure correct contract line item references, and maintain up-to-date payment information.
Errors in billing can result in payment delays, rejected invoices, withheld funds, or debt collection actions. Understanding DFAS processes improves cash flow reliability.
Example Scenario
A contractor completes work under a cost-plus contract. The contractor submits an invoice through the designated DoD payment system. DFAS confirms funding availability, validates invoice details, and processes payment via electronic transfer. If documentation is incomplete, DFAS may reject the invoice until corrections are made.
Common Misconceptions
DFAS only handles military payroll.
DFAS also processes contractor payments and maintains DoD accounting records.
DFAS determines contract performance.
Performance oversight is handled by agencies such as DCMA and DCAA. DFAS focuses on financial processing.
Payment delays are always DFAS errors.
Most delays result from incomplete invoices, funding issues, or missing documentation.
