Procurement Integrated Enterprise Environment (PIEE)

The Procurement Integrated Enterprise Environment (PIEE) is the Department of Defense's consolidated web-based platform for procurement and contract administration tools, replacing the fragmented collection of separate DoD procurement systems with a single sign-on portal.

What is PIEE?

PIEE is managed by the Defense Logistics Agency (DLA) and serves as the access gateway for several critical DoD procurement applications that contractors interact with throughout the contract lifecycle. The platform consolidates Wide Area Workflow (WAWF) for electronic invoicing, Electronic Document Access (EDA) for viewing contract documents, Vendor Pay inquiry for checking payment status, and additional modules for solicitation viewing and contract administration.

Before PIEE, each of these tools had separate registration processes, login credentials, and interfaces. A contractor performing on a DoD contract might need accounts in four or five separate systems to manage a single award. PIEE unified these under a single account structure where a company's Group Administrator manages access and grants permissions to individual users based on role - whether invoicing, receiving, or contract review.

Registration in PIEE requires an active SAM.gov registration with a current Unique Entity Identifier. The company administrator registers the organization at piee.eb.mil, and individual users are then provisioned with role-appropriate access. PIEE uses two-factor authentication and CAC (Common Access Card) compatibility for high-security access tiers. Access is required before a contractor can submit its first invoice or access contract documents on DoD awards.

Why PIEE matters for government contractors

Any company holding or pursuing DoD contracts needs PIEE access established before contract performance begins. Delays in PIEE registration translate directly to delays in getting paid, since WAWF - the only accepted electronic invoicing path for DoD - lives inside PIEE. New contractors frequently underestimate the setup time required and submit their first invoice weeks after it should have gone in, disrupting cash flow. Establishing PIEE access as part of the post-award onboarding process, not after the first delivery milestone, is standard practice among experienced DoD contractors.

Example

A small IT firm wins its first Army contract for software development support. The contracts manager immediately registers the firm in PIEE, designating herself as Group Administrator. She provisions the program manager with WAWF invoicing access and the CFO with vendor pay inquiry access. When the first deliverable milestone passes, the program manager logs into PIEE, opens WAWF, creates a 2-in-1 invoice against CLIN 0001, and submits it electronically. The CFO monitors payment status through the vendor pay module without needing to contact the contracting office. The firm receives payment within 28 days of invoice acceptance.

Frequently Asked Questions

Is PIEE registration the same as SAM.gov registration?

No - they are separate systems. SAM.gov registration establishes your entity in the federal contractor database and is required first. PIEE registration uses your SAM.gov UEI to create an account in the DoD procurement platform. You need both for DoD contracts: SAM.gov to be eligible for award, PIEE to invoice and access contract documents.

What modules are available in PIEE?

The main contractor-facing modules are WAWF (invoicing and receiving), EDA (Electronic Document Access for viewing awarded contracts and modifications), MyInvoice/Pay inquiry (checking payment status), and Solicitation Module (viewing and downloading DoD solicitation documents). The full suite of available modules depends on your user role and the contracts your company holds.

How long does PIEE registration take?

The initial registration process typically takes one to three business days for account approval. However, gaining access to specific modules may require additional approval steps depending on the sensitivity of the data involved. Starting PIEE registration immediately after receiving a contract award notice - not after the first delivery - ensures no payment delays.

What if my company already had a WAWF account before PIEE?

If your company had legacy WAWF access before DLA launched PIEE, those accounts were migrated to PIEE. However, login credentials and the access portal changed. Companies with legacy WAWF accounts should verify that their existing users can still log in through the PIEE portal and that role assignments transferred correctly.
