What Is PIEE, and What Do Defense Office Codes Mean?
PIEE is the Defense Department's online procurement system. Some Defense notices link to its Solicitation Module, where you get the solicitation and submit your offer, and Defense contractors send invoices through it.
PIEE (Procurement Integrated Enterprise Environment) in plain English
A notice that says "PIEE Solicitation Module Link" posts its files, and often takes offers, in PIEE instead of on SAM.gov. You need your own PIEE vendor account, tied to your company's CAGE code, to submit there, so set it up well before the due date. Defense invoicing (Wide Area Workflow) runs in PIEE too.
Defense offices are known by a six-character code (a DoD activity address code). The first letter shows the service: W for the Army, N for the Navy, F for the Air Force and SP for the Defense Logistics Agency. An office line such as "W07V ENDIST St Louis" is SAM.gov's short name for an Army Corps of Engineers district office.
The solicitation number starts with that code, then the last two digits of the fiscal year, then a letter for the type: Q for a request for quotations, R for a request for proposals and B for an invitation for bids.
Example: W912P927QA001 comes from Army office W912P9, in fiscal year 2027, and is a request for quotations.
