PSC R799 is the residual code of the R7 management support series, and the series it closes is a curious one. R7 has dedicated codes for advertising (R701), data collection (R702), accounting (R703), auditing (R704), debt collection (R705), logistics (R706), acquisition support (R707), public relations (R708), financial services (R710), banking (R711), coin minting (R712), and banknote printing (R713). It has no code for the generic "manage this business function for us." That gap is why $3.0 billion landed in R799 during FY2025.
The NAICS profile
Management consulting 541611 leads at $477 million, then engineering services 541330 at $370 million and Facilities Support Services (561210) at $369 million, with 541519 at $265 million and 541512 at $261 million. Consulting, engineering, facilities, and IT within a few hundred million of each other is the signature of a code that means "management support, subject unspecified."
PSC versus NAICS, briefly
Think of the PSC as the receipt line and the NAICS code as the industry label on the solicitation; both appear on every contract action.
If you sell business process or management support, watch R799 alongside R408 and R499. Those three residual and near-residual codes together carry more money than most named service codes in the entire manual.
PSC R799 FAQ
What does PSC R799 cover?
Management support services outside the named R7 codes. The R7 series covers advertising, accounting, auditing, debt collection, logistics, acquisition support, public relations, financial services, banking, and currency production, so R799 takes the remainder.
What NAICS codes win R799 work?
FY2025 obligations spread across 541611 at $477 million, 541330 at $370 million, Facilities Support Services (561210) at $369 million, 541519 at $265 million, and 541512 at $261 million.
How is R799 different from R499?
R499 is the leftover code for professional services, R699 for administrative services, and R799 for management services. The three-way split reflects the R category's own structure, not a real difference in the work being bought.
Does R799 include program management?
It should not. Program management has a dedicated professional-series code, R408. In practice, broadly scoped management support contracts that include a program management component often land in R799 anyway.
