Selling to Prime Contractors: How Space Suppliers Win Work
TL;DR: Selling to a prime contractor means selling to its supply chain, engineering and small business teams, not to the government directly. Find the programs that need your capability, get on the prime's supplier radar through its small business office, events and SBA's SUBNet, pass its qualification process and market with proof that you'll deliver on time and to spec. Primes often have formal reasons to buy from small businesses, so make it easy for them to say yes.
Key takeaways
- Primes buy through supply chain, engineering and small business teams. Market to all three.
- Many large federal contracts require small business subcontracting plans with goals.
- Qualification and quality systems matter as much as price.
- Relationships start at events and industry days, long before a purchase order.
Why should space suppliers sell to prime contractors?
For many components, software and services, primes are where the volume is. They hold large government contracts and need suppliers to deliver them. Selling to a prime can also build the past performance you need to win government work directly later.
There's a structural reason primes look for small suppliers too. The SBA explains that federal contracts awarded to other than small businesses over a certain dollar threshold must contain a small business subcontracting plan, following the requirements of FAR 52.219-9, in which the prime sets goals for what it plans to subcontract to small businesses. That gives primes a real incentive to find capable small suppliers.
Who do you actually sell to at a prime?
A prime is not one buyer. Map at least three groups:
| Team | What they care about | How to reach them |
|---|---|---|
| Supply chain / procurement | Price, delivery, terms, supplier risk | Supplier portals, small business office, RFQs |
| Engineering / program | Specs, performance, integration, heritage | Technical conferences, papers, demos, referrals |
| Small business liaison | Meeting subcontracting goals with capable suppliers | Small business office, outreach events, matchmaking |
Engineering creates the need, supply chain runs the buy and the small business office opens doors. Your marketing should speak to each.
How do you get on a prime contractor's supplier list?
- Register and get your basics in order. SAM.gov registration and a UEI, NAICS codes and size status. The SBA notes that registration in SAM is required to take part in government contracting, and primes often check it.
- Register in the prime's supplier portal. Most large primes have one. Fill it in completely.
- Contact the small business liaison. Send your capability statement and ask how they match suppliers to programs.
- Watch SUBNet. The SBA says primes can post subcontracting opportunities, including solicitations, to its SUBNet database, and small businesses can search them.
- Show up at outreach events. Matchmaking events and industry days put you in front of buyers who are actively looking.
What do primes need to see before they buy?
Primes carry program risk. Before they add you, expect them to look for:
- Quality systems. Certifications and documented processes relevant to your product.
- Delivery record. Evidence you ship on time and to spec.
- Technical proof. Test data, heritage or qualification results.
- Financial stability. Confidence you'll be around for the life of the program.
- Compliance readiness. Export control, cybersecurity and contract flow-down requirements.
Build a proof library that answers each of these, and put the essentials on your website. Our space sales objection guide covers how to answer the risk questions primes ask.
How do you market to prime contractors?
Be specific about programs. "We supply radiation-tested power boards for small satellite buses" beats "we serve aerospace."
Publish engineer-grade content. Datasheets, test summaries and application notes help engineers specify you early.
Make your capability statement excellent. One page, clear capabilities, codes, past performance and a direct contact.
Show up in person. Trade shows and technical conferences are where prime engineers and buyers meet suppliers. Our space industry conferences and trade shows guide lists the events worth your budget.
Use LinkedIn deliberately. Connect with engineers and supply chain managers on your target programs and share real progress. Our LinkedIn ads guide for space companies shows how to target by company and job title.
Follow up like it's a long cycle, because it is. Track every contact in a CRM, tag by program and stay in touch with useful updates. See our guide to lead qualification for space companies for deciding who to prioritize.

How long does it take to become a supplier to a prime?
It varies. Qualification, first-article inspection and program timing all play a part. Plan for months of relationship building, and start well before the program you want reaches its buying phase. Our space industry lead generation approach is designed for exactly this kind of long, account-based cycle.
Should you sell to primes or to the government directly?
Often both, at different times. Primes are frequently the faster first step for components and services, and they build past performance. Direct government work makes sense once you have a product that solves an operational problem on its own. Our guides on how to sell to the Space Force and how to sell to NASA cover the direct paths.
What mistakes do suppliers make with primes?
- Pitching only procurement. Engineering often decides who gets considered.
- Weak capability statements. Vague one-pagers get filed and forgotten.
- Ignoring the small business office. It exists to find suppliers like you.
- Underestimating qualification. Quality systems and documentation take time.
- Disappearing between programs. The prime remembers suppliers who stay in touch.

What does a strong supplier capability statement include?
Primes and their small business liaison officers see a lot of capability statements. Make yours easy to scan:
- Core capabilities in one or two lines each, written in the prime's language.
- Past performance with outcomes, even if it's commercial or subcontract work.
- Differentiators that matter to a prime: schedule reliability, quality systems, test heritage.
- Company data: UEI, CAGE code, NAICS codes and certifications.
- One contact who will answer quickly.
Keep it to one page, tailor it to each prime's programs and bring printed copies to industry days. A capability statement that reads like a sales brochure gets set aside. One that reads like a supplier qualification summary gets filed with the program team.
