Set up PIEE before your first award ships. Allow time for the CAM and EB POC approvals.

Step 1: Set up your company in PIEE

1. Register in SAM.gov. This is required, and it's where your CAGE code and Electronic Business point of contact (EB POC) come from.
2. Get your CAGE code into the PIEE vendor group structure. This is a one-time step.
3. Designate a Contractor Administrator (CAM). Every vendor group needs at least one. The CAM manages PIEE access for your company's users. If the EB POC listed in SAM.gov registers as CAM, no extra paperwork is needed. If someone else is CAM, the EB POC has to approve it.
4. The CAM self-registers in PIEE. Only the Contractor Administrator role can be added at first.
5. Add roles and users. Once the CAM is active, request WAWF vendor roles for whoever will submit invoices. PIEE notes that registering for WAWF also gives you access to myInvoice.

At a very small company, one person may be EB POC, CAM and invoice submitter. That's fine. Just make sure the EB POC in SAM.gov is current, or the CAM approval stalls.

Step 2: Read the WAWF instructions in your contract

• Document type. For fixed-price line items that ship a deliverable, you submit the invoice and receiving report the contracting officer specifies.
• Routing DoDAACs, including Inspect By and Accept at Other, from the Routing Data Table. Match them to the inspection and acceptance points on your award. Copy the DoDAACs from the contract exactly.

Step 3: Create the invoice and receiving report

In WAWF, as a vendor:

1. Start a new document and enter your contract number (the PIID) and, for orders under a basic contract, the delivery order number.
2. Enter the pay office DoDAAC from the contract. WAWF shows the document types available for that pay office.
3. Pick the document type your contract specifies, such as Invoice and Receiving Report (Combo).
4. Fill in the routing codes. WAWF tries to prefill from the contract record. Check every field against your award.
5. On the line items, enter the CLIN, quantity shipped, unit of issue and unit price, matching the contract line exactly.
6. Add shipment details: shipment number, ship date and, where it applies, the tracking or bill of lading number.
7. Attach what the contract asks for, then submit.

WAWF's training also notes a catch for combo documents. If the inspector or acceptor DoDAAC has no active users in WAWF, the web screen tells you to submit a stand-alone invoice instead.

Step 4: Track payment in myInvoice

Once you submit, the receiving report goes to the government inspector or acceptor, and the invoice goes to the pay office. Use myInvoice, which you can reach through PIEE, to see where an invoice is in that process. If a document is rejected, WAWF sends it back with a reason. Fix that exact problem and resubmit rather than starting a duplicate.

Common WAWF mistakes that delay payment

• Wrong document type. Use the one in your contract's 252.232-7006 clause.
• Routing codes typed from memory. Pay office, admin and inspector DoDAACs differ by contract. Copy them from the award.
• Line items that don't match the contract. CLIN, unit of issue, quantity and unit price must match. A per-piece price on a per-package line gets rejected.
• Wrong inspection or acceptance location. It has to match the award.
• Duplicate invoices. Resubmitting a rejected document as a new one creates confusion. Correct and resubmit.
• An inactive CAM. If your only CAM leaves the company, nobody can add or restore users. Keep a backup.
