2.2 Billing Processes
2.2.1. Interfund Billings. Intragovernmental transactions between or within DoD
Components for the purchase of goods will be processed through the interfund billing system when
initiated and supported by the supply and accounting systems of both trading partners (also see
Volume 4, Chapter 3, section 5.0 for additional policy on intragovernmental receivables). As
prescribed by the Defense Logistics Management Standards (DLMS), Defense Logistics Manual
(DLM) 4000.25, Volume 4, Chapter 5, (C5.1.2), Interfund Billing System Procedures, the GSA,
Federal Aviation Administration, and the National Oceanic and Atmospheric Administration are
authorized federal agencies that may also bill DoD through the interfund billing system for goods
purchased. The interfund billing system allows suppliers to reimburse themselves at the time of
the billing from appropriations designated by the customer. The supplier forwards an automated
billing to the billed office and reports to the U.S. Department of the Treasury (Treasury) a
reimbursement of the supplier’s funds with an offsetting charge to the customer’s funds. Interfund
bills, therefore, serve as both a billing and a notice to the customer that its funds have been charged
and the bill has been paid. Only the billing office or the Central Accounts Office is authorized to
adjust, or otherwise reverse, reimbursements reported to the Treasury on behalf of the billing
office. See the DLM 4000.25, Volume 4 for detailed interfund billing system procedures.
* 2.2.2. Non-Interfund Billings. Intragovernmental transactions between DoD Components
that are not initiated and supported by the supply and accounting systems of both trading partners,
and are unable to be processed through the interfund billing system (described in subparagraph
2.2.1), are classified as non-interfund transactions. This includes intragovernmental transactions
between a DoD Component and a non-DoD entity, which are not authorized for interfund billing
in accordance with the DLM 4000.25, Volume 4, Chapter 5. The TFM, Volume 1, Part 2, Chapter
4700, Appendix 8, section 2.6, provides policy and guidance on the use of the Intragovernmental
Payment and Collection (IPAC) system by federal entities, including the DoD, to electronically bill
and pay for non-interfund intragovernmental transactions. Appendix 8, section 1 of the referenced
TFM also provides guidance and information related to the development, use of, and required
implementation dates of G-Invoicing as the platform for creating and managing intragovernmental
transactions. G-Invoicing is not an accounting system nor a procurement system; instead, it serves
as a gateway for federal entities to agree upon the funding terms and the accounting treatment of
their reimbursable activity, and exchange that data with one another for consistent financial
reporting. IPAC will continue to operate as the application for the settlement of funds between
federal entities, even in a G-Invoicing environment, per the TFM. The IPAC system communicates
to the Treasury and the trading partner agency that the online billing and payment for services and
supplies has occurred. Refer to TFM, Volume 1, Part 2, Chapter 4700, Appendix 8 for additional
information on G-Invoicing and IPAC respectively. See Volume 5, Chapter 11 for disbursing policy
related to IPAC processes and Volume 4, Chapter 3 for accounting policy related to non-interfund
receivables policy. Volume 5, Chapter 11, paragraph 4.4 provides policy concerning monthly cutoff
dates for IPAC processing.
2.2.3. Advance Payments. Unless the DoD Component is specifically authorized by law,
legislative action, or Presidential authorization, funds are not to be advanced to non-DoD federal
entities, or be used to pay for advance billings without the receipt of goods or services. The
constructive delivery and drop from inventory methods described in paragraph 2.4 are exceptions
