Notification of Defense Agency Initiative Release 12 (DAI R12) Upgrade

Due to the R12 upgrade the DAI system will be down from April 23 - May 3, 2015. Payments issued through the DAI system ("for self"), or where DAI is required to support prevalidation processes for payments in other entitlement systems, will be held until the upgrade is complete.  It is anticipated that the DAI downtime will have a minimal impact on the overall timeliness of the payment processes, but emergency requests (both payments and prevalidations) can be processed on an as needed basis.

For planning purposes please note the following key dates for the upgrade:

  • Friday, April 17 - Final DAI foreign currency payment cycle
  • Tuesday, April 21 - Final DAI "for self" payment cycle
  • Wednesday, April 22 - Final prevalidation files processed*
  • Monday, May 4 - Prevalidation processing resumes
  • Tuesday, May 5 - "For self" payment processing resumes

*Note - The prevalidation files must be available in DAI for processing by April 22 to be approved prior to the downtime.  For example, MOCAS prevalidation requests must be included on the MOCAS file that will interface to DAI on the night of April 21.

Important information for MOCAS Pay Office DoDAACs: HQ0337, HQ0338 and HQ0339:

DFAS is working to minimize delays in processing payments for invoices with missing Receiving Reports. To help with this effort, DFAS recommends that all invoices include the Proof of Delivery document as an attachment in WAWF. Adding this document helps Receiving Activities validate that all items delivered were properly received and accepted in accordance with regulatory requirements. This will help facilitate a faster payment to you.


Accelerated Payments to Prime Contractors

DFAS will begin accelerated payments to Prime Contractors on August 1, 2014 as directed by OMB Memorandum M-14-10 (July 10, 2014) and OMB Memorandum M-12-16.

The agency goal is to release payments as soon as possible upon receipt of the required documentation, which includes the following:

  • Valid Invoice
  • A properly signed Receiving Report (Government Acceptance)
  • Sufficient obligation of funds


If payments are delayed because of DFAS processing, Prompt Payment Interest will be calculated based on the Net terms of the contract.

Please utilize the DFAS self-service tools to inquire as to the status of your invoice, located at

Additional questions can be directed to our customer care center, 1-800-756-4571.

Accelerated payments to all Small Business Contractors will continue to remain in place.
