About the company
Mcdemus & Co LLC, doing business as Mcdemus & Co., CPA, is an SBA 8(a) certified small disadvantaged business based in Manassas, Virginia, providing federal audit support and accounting services as a prime contractor (100% of recent awards) on a GSA Multiple Award Schedule. The vendor is a black American-owned, minority-owned limited liability company certified as a Small Disadvantaged Business and DOT-certified Disadvantaged Business Enterprise, with an 8(a) Program Participant designation running through January 2027.
Mcdemus & Co has delivered two federal prime awards in the source data spanning 2017 to 2023, totaling $1.8 million in combined potential value. The Department of the Interior and the GSA Federal Acquisition Service each account for one award. The primary named engagement is a time-and-materials delivery order valued at $818,359.20 awarded by the Department of Interior's Office of Policy Management and Budget on September 15, 2023, for audit support services to the Indirect Cost and Contract Audit Division within DOI's Financial Management Directorate. The work runs through September 30, 2026, under the GSA Multiple Award Schedule and carries a Total Small Business set-aside designation. This contract represents continuation of audit expertise critical to DOI's indirect cost rate reviews and contract audit functions across departmental entities and contractors. A second award of approximately $1 million was issued by GSA Federal Acquisition Service. Both awards sit outside defense and intelligence markets — they address civilian financial management and compliance audit needs.
The vendor operates solely as a prime (100% of awards) with no subcontractor footprint in the source data. On the GSA Schedule, Mcdemus & Co offers three labor categories ranging from $59.47/hr for a Staff Accountant (bachelor's degree, one year experience, no clearance) through $89.20/hr for a Project Manager (technical school or certification, five years experience). No cleared labor roles are offered. Service Contract Inventory data shows minimal invoiced activity — $90 thousand across FY2024 with 0.8 FTEs on the prime contract — and an effective government-paid rate of $53.86/hr, reflecting the early-stage invoicing under the 2023 award. One award worth $818 thousand reaches ultimate completion within the next twenty-four months and faces recompete exposure in that window. The vendor's footprint is small and narrowly focused on audit and accounting services to interior-sector civilian customers, with no evident defense or intelligence customer base or subcontracting pipeline.
