NASA Implements E-Invoicing Solution

NASA's implementation of Department of Defense's Wide Area Workflow (WAWF) eInvoicing solution recently went live for nearly 50 NASA contracts identified with Defense Contract Audit Agency (DCAA) /Defense Contract Management Agency (DCMA) approved invoices.   WAWF is a secure web-based system for electronic invoicing, receipt and acceptance. WAWF allows government vendors to submit and track invoices and receipt/acceptance documents over the web and allows government personnel to process those invoices in a real-time, paperless environment.


Transitioning to WAWF has many benefits. WAWF will provide vendors with an electronic mechanism to submit invoices and eliminate the requirement to submit a paper invoice. The implementation will also allow for improved payment cycle time, and reductions in late payments and interest penalties, and the cost of processing transactions.
