Wide Area Workflow (WAWF)

Wide Area Workflow (WAWF) is the Department of Defense's mandatory electronic invoicing and document submission system, used by defense contractors to submit invoices, receiving reports, and acceptance documentation for payment on DoD contracts.

What is Wide Area Workflow?

WAWF is a web-based application managed by the Defense Finance and Accounting Service (DFAS) and is required for virtually all DoD contracts above the micro-purchase threshold. Before WAWF, defense contractors submitted paper invoices through multiple channels with no standardized process, causing payment delays and administrative burden on both sides. WAWF replaced that fragmented process with a single electronic system where contractors, contract administrators, and receiving officials all interact on the same platform.

In WAWF, a contractor logs in after delivering goods or completing a service milestone and creates an invoice document tied to the contract's PIID (Procurement Instrument Identification Number). The system routes the document electronically to the Contracting Officer's Representative for acceptance, then to the paying office for payment processing. The system supports multiple document types: 2-in-1 (invoice and receiving report combined, most common for services), combo (invoice and receiving report for goods), cost vouchers (for cost-type contracts), and stand-alone receiving reports. WAWF is now part of the broader Procurement Integrated Enterprise Environment (PIEE) platform.

Payment terms under the Prompt Payment Act require the government to pay within 30 days of a proper invoice. WAWF creates a timestamped audit trail showing exactly when an invoice was submitted and accepted, which is essential for calculating interest on late payments. Contractors on DoD contracts need WAWF access configured before their first delivery, as invoices submitted outside the system are generally rejected.

Why WAWF matters for government contractors

For any contractor performing on DoD contracts, WAWF is the only path to getting paid. A contractor who submits an invoice outside WAWF, who makes errors in the document type selection, or who fails to match the invoice to the correct CLIN structure will face rejection and payment delays. Understanding the document routing process - who accepts what, at which step, with what timeline - is essential cash flow management. Many new DoD contractors experience their first payment delays not from contract disputes but from WAWF submission errors.

Example

A professional services firm wins a $3.8 million Army IT support contract with monthly invoicing. After month one, the contract specialist logs into WAWF and creates a 2-in-1 invoice for services rendered, referencing CLIN 0001 and attaching a timesheet summary. The system routes the invoice to the COR for acceptance, then to the DFAS payment office. The COR accepts within five business days, and DFAS processes payment within the 30-day Prompt Payment Act window. The firm's accounts receivable team monitors status in WAWF rather than chasing individual contacts at the agency.

Frequently Asked Questions

How do I get WAWF access as a new contractor?

WAWF access is set up through the PIEE portal at piee.eb.mil. Your company needs an active SAM.gov registration with a valid UEI. The company's designated administrator (Group Administrator role) registers the organization and then grants access to individual users. Your contracting officer will typically reference the WAWF requirement in the contract's payment clause and can provide guidance on the specific document types required.

What is the difference between WAWF and PIEE?

WAWF is the invoicing module within the PIEE (Procurement Integrated Enterprise Environment) platform. PIEE is the umbrella system that consolidates multiple DoD procurement applications, including WAWF, Electronic Document Access (EDA), and vendor pay inquiry tools. When DoD transitioned to PIEE, WAWF retained its name but became accessible through the PIEE portal.

What happens if I submit the wrong document type in WAWF?

If you select the wrong document type - for example, submitting a combo document when a 2-in-1 is required - the government will typically reject the submission and ask you to resubmit correctly. This resets the payment clock. Your contract's payment clause (typically FAR 52.232-25 or DFARS 252.232-7003) specifies the required document types. When in doubt, contact your administrative contracting officer before submitting.

Can I use WAWF for non-DoD federal contracts?

WAWF is a DoD system. Civilian agency contracts use different invoicing systems - GSA contracts often use the GSA's own payment portals, and other agencies use systems like IPP (Invoice Processing Platform) managed by Treasury. Always check your specific contract's payment clause to determine which system the agency requires.
