GDIT (General Dynamics IT) runs roughly $8 billion in annual revenue as the IT services arm of General Dynamics. Its customers include the Department of Defense, the Department of Homeland Security, the Department of Veterans Affairs, and dozens of other federal agencies. That scale creates a large and active subcontracting market. Prime contracts at this level require detailed subcontracting plans, which means GDIT actively needs small and diverse businesses to fill them.
If you run an IT services, professional services, cybersecurity, logistics, or facilities company, GDIT is worth pursuing. Here is how the process works.
What GDIT buys from external suppliers
GDIT's external spend breaks across a few categories. The largest is IT products and services: hardware, software licenses, cloud infrastructure, cybersecurity tools, and managed services. Professional services come second, including program management support, data analytics, systems engineering, and consulting. Facilities and logistics services round out the third category, covering base operations support, maintenance, and related work tied to GDIT's field presence.
Subcontracts vary from a few hundred thousand dollars on task orders to multi-year arrangements on large programs. Because GDIT operates on cost-plus and firm-fixed-price contracts with federal agencies, subcontractor pricing needs to be competitive and documentable. Come prepared with GSA schedule pricing or current market rate justifications if you have them.
How to register as a supplier
GDIT uses a supplier portal for new vendor registration. Search for "GDIT supplier portal" or navigate to the supplier section of gdit.com to find the current registration link. The portal collects standard procurement information: your legal business name, SAM.gov Unique Entity Identifier (UEI), NAICS codes, business size classification, cage code, and primary contact details.
Before you register, make sure your SAM.gov registration is active. Federal prime contractors are required to verify subcontractor eligibility through SAM, and an expired or missing SAM registration will hold up any purchase order. Registration on SAM is free and takes one to two weeks for initial processing.
Within the GDIT portal, you will also be asked to indicate your small business and diversity certifications. This is not optional or decorative. GDIT's contracting officers use this data when building subcontracting plans and when responding to solicitations that include diversity spend targets. Mark every certification that applies.
Which certifications carry the most weight
GDIT participates in four primary diversity organizations: NMSDC, WBENC, NaVOBA, and Disability:IN. Each maps to a different business owner category.
NMSDC certification (MBE) carries significant weight at GDIT because minority-owned small businesses represent one of the largest tracked categories in federal subcontracting plans. If you are eligible, pursue NMSDC certification through your regional affiliate council. Certification typically takes 60 to 90 days and requires an on-site or virtual review of ownership, control, and day-to-day management.
WBENC certification (WBE) is the standard for women-owned businesses in the corporate supplier diversity space. GDIT tracks WBE spend across its programs, and WBENC-certified firms appear in the WBENC database, which procurement staff search when building diverse supplier slates.
NaVOBA certification (Veteran Business Enterprise) is relevant given how much of GDIT's work sits inside DoD and VA. Federal contracts often include veteran-owned small business targets, and NaVOBA certification complements your federal SDVOSB or VOSB designation if you have one.
Disability:IN certification (Disability-Owned Business Enterprise, or DOBE) reflects GDIT's commitment under its Disability:IN membership. Disability:IN-certified firms get access to the National Supplier Diversity Database and introductions through Disability:IN's corporate-to-supplier matchmaking events.
If you hold federal certifications (8(a), WOSB, SDVOSB, HUBZone), include those in your registration as well. Federal certifications confirm your eligibility on government-funded subcontract dollars, which is most of what GDIT spends.
How diversity certification affects your chances
GDIT files detailed subcontracting plans with every large federal contract award. Those plans commit specific dollar percentages to small business, small disadvantaged business, women-owned small business, veteran-owned, and HUBZone categories. Failing to meet those commitments can affect contract performance ratings and future award decisions.
That creates real demand for certified diverse suppliers, not just symbolic interest. When a GDIT program manager needs to fill a subcontracting plan goal, suppliers already in the system with verified certifications move to the front of the list. Suppliers who show up after the plan is filed are harder to add.
Register and get your certifications documented before you pursue a specific opportunity. Waiting until you have a contract in front of you is too late.
Getting your first order
Cold registration alone rarely leads to work. Here is what actually moves things forward.
Find GDIT subcontracting opportunities through the Small Business Administration's SUB-Net database, where large prime contractors post subcontracting opportunities. GDIT also posts opportunities through its own supplier portal and responds to small business outreach through its procurement team.
Attend events where GDIT procurement staff are present. NMSDC and WBENC hold annual conferences where GDIT participates as a corporate member. Disability:IN's annual conference includes matchmaking sessions with member companies. NaVOBA's conferences serve a similar function for veteran-owned firms. These are not networking events in the generic sense. They are structured meetings where you can get in front of the right people in a format they have pre-approved for supplier discovery.
Request a small business introduction through GDIT's supplier diversity team. GDIT has a dedicated supplier diversity function; the relevant role is typically Director or Manager of Supplier Diversity within the procurement or supply chain organization. Contact information is available through the GDIT website or through your regional NMSDC, WBENC, or NaVOBA affiliate.
If you can match a specific contract vehicle GDIT already holds, mention it. Program managers respond better to "I can support your work on [specific agency] under your existing IDIQ" than to a general capability pitch.
Supplier development programs and events
GDIT participates in supplier development through the diversity organizations it supports. NMSDC regional councils run development programs, mentoring, and matchmaking that GDIT has historically engaged with. WBENC holds regional and national programming that includes corporate member participation.
GDIT also participates in federal small business matchmaking events coordinated through the Small Business Administration and agency-specific outreach days at DHS, VA, and DoD. These events let you register a brief meeting with procurement staff from multiple prime contractors in a single day.
One practical step: check GDIT's active contract vehicles on USASpending.gov. Search the company name, look at their largest active awards, and identify which agencies and program areas have the most spend. Then match your capabilities to those specific programs before reaching out. Generic outreach gets generic responses. Program-specific outreach gets meetings.
