WAWF / PIEE Invoicing
The Department of Defense's mandatory electronic invoicing and receiving system, Wide Area Workflow, now part of the PIEE eBusiness suite.
Definition
Wide Area Workflow (WAWF) is the Department of Defense's web-based system for electronic submission of invoices and receiving reports, removing paper from the receipt, acceptance, and payment process. It now lives inside the Procurement Integrated Enterprise Environment (PIEE) at piee.eb.mil — the integrated portal that also houses entity-registration support and other procurement modules.
For DoD contractors, electronic invoicing through WAWF is generally mandatory under DFARS clauses (such as 252.232-7003), and getting paid depends on submitting invoices and receiving reports correctly. New contractors commonly underestimate this back-office step: an award is only the start.
How this affects your proposal
Set up your PIEE/WAWF access as soon as you win a DoD award — payment depends on correctly submitted electronic invoices and receiving reports.
Common questions about wawf / piee invoicing
Is WAWF mandatory?
For most DoD contracts, yes — electronic invoicing via WAWF (within PIEE) is required under DFARS clauses such as 252.232-7003. Your contract's clauses specify the requirement.
Is WAWF the same as iRAPT?
They refer to the same DoD invoicing capability. The module was branded iRAPT for a period and then returned to the WAWF name within the integrated PIEE suite.
