INTERNATIONAL SOFTWARE SYSTEMS INC

International Software Systems Inc. specializes in custom computer programming and systems design services tailored to federal agency needs, with deep expertise in developing and sustaining mission-critical software solutions. The contractor delivers end-to-end programming services, including integration of complex regulatory frameworks like MOA 2024 into existing procurement systems, and supports long-term contract extensions through iterative software enhancements. Their technical proficiency spans full lifecycle software development, system architecture design, and engineering services that bridge operational requirements with scalable IT infrastructure. They demonstrate a strong command of federal compliance environments, particularly in deploying solutions that align with ongoing procurement and service delivery frameworks under GSA Schedules and Seaport-NXG platforms. The company has established sustained relationships with key federal agencies including the Department of Defense, Department of Transportation, General Services Administration, and Department of Health and Human Services. For DoD, they provide engineering services supporting naval acquisition systems; for DOT, they enhance transportation procurement platforms; for GSA, they maintain and extend Federal Supply Schedule capabilities; and for HHS, they design and extend enterprise-level systems supporting public health operations. Their engagements reflect a pattern of recurring, multi-year support rather than one-off deliveries, indicating trusted, long-term partnership status. Their primary focus lies in NAICS 541511 (custom computer programming) and 541512 (computer systems design), with supplementary work in engineering services under 541330. This positions them as a niche provider for federal agencies requiring bespoke software integration, legacy system modernization, and compliance-driven development—particularly in procurement, logistics, and public health domains. As a small business structured as a 2L entity based in Greenbelt, MD, International Software Systems Inc. operates with agility suited to federal contracting cycles. While currently holding no formal government certifications, their consistent performance across high-compliance agencies underscores their reliability and understanding of federal IT standards and acquisition protocols.
