One Stop Business Center LLC

One Stop Business Center LLC, a woman-owned, minority-owned small disadvantaged business operating as a sole proprietorship from Goose Creek, South Carolina, provides janitorial and custodial services to the National Park Service as a prime contractor under total small business set-asides. The vendor competes exclusively under the woman-owned small business (WOSB) and total small business designations, with all four recent awards routed through the Department of the Interior's National Park Service Southeast Region.

One Stop Business Center's federal footprint is narrow and localized. All four prime awards support janitorial operations at four National Park Service sites in the Charleston, South Carolina vicinity: Fort Sumter National Monument, Fort Sumter Liberty Square Visitor Education Center, Fort Moultrie National Historical Park, and Charles Pinckney National Historic Site. The largest award, a definitive contract from January 27, 2024, covers roughly 20,000 square feet across the four sites and runs through July 31, 2026, with a ceiling value of $437,004. A follow-on purchase order from May 4, 2026, valued at $458,796, extends janitorial services at Fort Sumter Liberty Square Visitor Education Center through July 31, 2029, with weekly service delivery, restroom maintenance, glass cleaning, floor care, and biohazard response. A third award, a purchase order from July 12, 2023, valued at $40,104, covered services at Fort Moultrie and Charles Pinckney through January 31, 2024.

Customer concentration is complete: the National Park Service Southeast Region accounts for 100% of recent awards and combined potential value ($1.5 million). The vendor operates exclusively in the janitorial services category (NAICS primary, PSC Housekeeping–Custodial Janitorial across all four awards). Activity is episodic — one award in 2019, then a gap through 2023, followed by one award each in 2023, 2024, and 2026 — reflecting recompete cycles tied to option-year expirations rather than organic growth. One award (the $437,004 definitive contract) faces ultimate completion in the next twenty-four months and triggers a recompete opportunity.

Service Contract Inventory data from FY2024 shows One Stop Business Center reported $531,000 in invoiced revenue on a single prime contract with 21.6 federal FTEs deployed, at a government-paid median hourly rate of $11.80 per hour — consistent with lower-tier janitorial labor markets. The vendor performs zero subcontracting across SCI-reportable prime contracts, indicating a vertically integrated delivery model. The vendor does not hold any parent contract vehicles, IDIQs, or government-wide seats; all work flows from direct purchase orders and definitive contracts issued by NPS.
