About SDG Systems LLC
SDG Systems LLC SDG Systems Division, a Harmony, Pennsylvania-based sole proprietorship and limited liability company, operates as a prime contractor delivering IT maintenance, software licensing, integration services, and specialized IT equipment and configuration support to federal civilian and defense agencies on a full-and-open basis, with no set-aside posture across its federal footprint.
SDG Systems competes across a highly fragmented customer base. Twenty distinct agencies account for recent awards, with concentration extremely diffuse: the Office of the Secretary of Defense anchors $2.5 million of the vendor's $3.8 million combined potential value (66% by dollars), but accounts for only one award; the GSA Federal Acquisition Service contributes $1 million (26%) across a single award; the Department of the Navy Information Warfare Systems Command, the National Gallery of Art, and the Department of the Air Force round out the top-five customers by potential value. By award count, the Air Force Air Mobility Command leads with three awards ($36 thousand combined), followed by the National Gallery of Art and Navy Information Warfare Systems Command, each with two awards ($45 thousand and $60 thousand respectively). The source names three recent representative contracts: a $39,240 purchase order from the National Gallery of Art for IT software to log and catalog sensitive items associated with art transportation (awarded August 2024, completed August 2025); a $5,555 firm fixed-price purchase order from the National Gallery of Art for IT maintenance services (awarded October 2025, completing October 2026); and a $21,208 purchase order from the Smithsonian Institution for licensing and integration services (awarded August 2023, completed October 2023).
SDG Systems places the bulk of its taskable work — four task orders carrying $2.6 million in combined potential value — under the Federal Supply Schedule GS-35F-0054X. The vendor operates purely as a prime contractor; no subcontract engagement appears in the source. Activity is sparse and episodic: one award each in 2023, 2024, and 2025, with only one award (potential value $6 thousand) reaching ultimate completion inside the next twenty-four months. Work straddles electronic computer manufacturing and custom computer programming (seven awards each), computer and software retail (six awards), and computer peripherals and IT support equipment (five awards combined), reflecting a portfolio oriented toward IT equipment procurement and integration rather than sustained service delivery.
