# DoD Clarifies One Pay Invoice Routing Transition

A procurement community discussion clarifies that WAWF is not sunsetting; the reported transition concerns One Pay, a payment system behind WAWF, and does not generally change how contractors submit invoices through PIEE/WAWF. Contractors should review their latest contract modification for any change to the Pay Office DoDAAC before invoicing, as invoices routed to a former destination may be rejected. The discussion also reports that vendor roles remain unchanged, while PIEE accounts may deactivate after 34 days of inactivity.

- Check the latest contract modification for a changed Pay Office DoDAAC and route invoices to the updated destination where applicable.
- Contractors can continue using their existing PIEE/WAWF invoicing process unless their contract modification specifies a routing change.
- Keep PIEE accounts active; the discussion reports that accounts may deactivate after 34 days of inactivity.

### Key Quotes
> Before your next invoice, pull your most recent contract modification and check whether the Pay DoDAAC changed. If it did, route to the new one. Invoices sent to the old DoDAAC get rejected.
