Wide Area Workflow (WAWF)

Definition

Wide Area Workflow (WAWF), now part of the Procurement Integrated Enterprise Environment (PIEE), is the DoW electronic system contractors use to submit invoices, receiving reports, material-inspection-and-receiving reports, and shipping documents. The government's inspectors and contracting officers review and approve these documents through WAWF/PIEE, which routes payments to DFAS for disbursement. Using WAWF is mandatory for DoW invoicing under DFARS 252.232-7003.

Why It Matters

Billing correctly through WAWF/PIEE is the single most common operational issue for new DoW contractors. Misrouted invoices, incorrect CLIN references, or wrong PIID structure can delay payment by weeks or months. Training your accounting team on WAWF, understanding the approval routing for your contract, and maintaining a disciplined invoicing cadence prevents cash-flow surprises and builds trust with the CO.

Example

A firm's first WAWF invoice is rejected because the CLIN referenced doesn't match the contract structure. The firm corrects and resubmits, is paid 12 days later, and updates its billing SOP to prevent recurrence.
