Federal Aviation Administration (FAA) contractors and vendors are advised that all FAA Accounting Office's will have a "very limited" payment capability between September 27 to November 5 due to activities supporting conversion to FAA's new accounting system, DELPHI.

For, this reason vendors who receive payment from the FAA William J. Hughes Technical Center, Accounting Services Group (ACX-32) should consider accelerating invoicing cycles, where needed, to preclude cash flow problems affecting continuation of FAA services during the transition. Vendors desiring to accelerate billing should plan to have invoices for most recent completed and/or delivered services, material, and supplies delivered to ACX-32 no later than COB September 16th to assure payments can be reviewed, approved, and processed prior to the September 27 deadline.

The Accounting Office will still require invoices to be reviewed and approved by the appropriate FAA Contracting Officer Technical Representative (COTR) before payment. Vendors are therefore advised to submit a courtesy copy of their invoice to the FAA COTR where deemed appropriate, to facilitate a timely review and approval. Invoices received during transition will be paid after DELPHI becomes operational on November 5.

Please also be aware that vendor revenues from purchases made with the Government purchase card will not be impacted by conversion. Vendors will receive payment from Bank of America as usual.
