GM buys from thousands of companies, and almost none of them got in by filling out a form on gm.com. That's the first thing to understand before you spend a weekend hunting for an application. General Motors does not award direct business off a cold submission. There's a process, it favors suppliers a GM buyer already wants, and it has changed in important ways since 2024.
Here's how it actually works, what the 2025 diversity shift means for you, and the realistic order to approach it in.
Two different doors, and you need to know which one you're atPeople searching "how to become a GM supplier" are usually standing at one of two very different doors, and they get conflated constantly.
The first is GM SupplyPower, the transactional portal (run on Covisint) that GM's active Tier 1 and approved Tier 2 suppliers use to manage purchase orders, quality, shipping, and compliance. You cannot self-register for SupplyPower. Access is invitation-only: a GM buyer or engineering contact sponsors you, and you need a verified DUNS number from Dun & Bradstreet before they can onboard you. If a website offers to "register you for GM SupplyPower" for a fee, close the tab. SupplyPower is the door you walk through after GM has decided to buy from you, not before.
The second is GM Supplier Acceleration, GM's outward-facing program for small businesses that want to build a relationship and get developed into the supply base over time. This is the door most new suppliers should actually approach. It's the one with an open registration form. We'll spend most of this guide here.
What GM Supplier Acceleration isGM Supplier Acceleration is the current name for what most people still call GM's supplier diversity program. GM ran a formal supplier diversity program starting in 1968, one of the first automakers to do so, and for decades it tracked billions in spend with minority- and women-owned firms. As recently as 2023, GM reported roughly $8.5 billion in purchasing with diverse suppliers in North America.
That framing changed. In April 2025, GM stopped publicly counting its diverse-supplier spend, part of a broader pullback across the auto industry after federal executive orders targeting diversity programs. The program didn't disappear. It was rebranded and reframed around "economic inclusion" and small-business growth rather than demographic categories.
Read the current eligibility language and you'll see the shift in plain terms. To register for Supplier Acceleration, a business must be considered small and be headquartered in North America, and must "demonstrate a commitment to supporting and promoting economic growth and inclusion in local communities." GM states that all programming "will be equally available to all registered suppliers who meet these criteria without regard to the race/ethnicity, gender or other protected characteristics of the business owners or leadership."
In other words: GM still wants to develop small suppliers, but it is no longer a program you qualify for by being minority-, women-, veteran-, or LGBTQ-owned. If you're a certified diverse business, that's still useful for credibility and for other buyers' programs. It is no longer a GM gatekeeper.
How to register for Supplier AccelerationThe registration itself is short. From gmsupplieracceleration.com, the Registration page links out to an online form (currently hosted on an OutSystems portal) where you submit your company details. There's no fee.
Before you fill it out, get these in order so your profile reads like a serious vendor:
- Your DUNS number. GM's systems run on it. If you don't have one, request it free from Dun & Bradstreet first.
- A tight capability statement. One page: what you make or do, your NAICS codes, certifications, plant or service footprint, and named customers. GM buyers think in commodities and platforms, so describe what you supply in their language, not yours.
- Your relevant certifications. ISO/IATF quality certs matter enormously in automotive. Diversity certifications (NMSDC, WBENC, NGLCC, Disability:IN, NaVOBA) still signal credibility to corporate procurement broadly, even though GM's own program no longer requires them.
- Realistic capacity numbers. Revenue, employee count, and the largest order you can actually fulfill. Overstating here gets found out fast.
Registering puts you on GM's radar and into its development programming. It does not put a purchase order in your hand.
The realistic timeline, and why most suppliers don't get in fastSet expectations now. Suppliers routinely describe years between first contact with GM and a first direct award. Automotive sourcing runs on long program cycles, brutal quality and cost requirements, and incumbents who've held their commodity for a decade. A small company rarely wins a Tier 1 production contract straight off the street.
That isn't a reason to skip GM. It's a reason to approach it the way that actually works.
Start at Tier 2, not Tier 1. Most realistic entry points into a big automaker run through its existing Tier 1 suppliers. GM expects its primes to develop their own subcontracting base, and a Tier 1 that wants to show a healthy, growing supply chain is often an easier first customer than GM's central purchasing. Win work with a company that already sells to GM, deliver flawlessly, and you build the past performance that makes you credible for direct work later.
Use the program for what it's for. Supplier Acceleration is development, not procurement. Treat the training, the introductions, and the buyer exposure as the point. Show up, perform, and let GM's team see you're someone they'd want in the chain.
Get specific about who buys what you sell. GM purchasing is organized by commodity. A generic "we'd love to work with GM" goes nowhere. Knowing which buyer or which Tier 1 owns your commodity is worth more than any form.
Where diversity certification still pays offIf you're a minority-, women-, veteran-, or LGBTQ-owned business, GM's policy change shouldn't talk you out of certifying. It should change why you certify.
Plenty of automakers and Fortune 500 buyers still run active supplier diversity programs with real spend goals, and many require third-party certification from bodies like NMSDC for minority-owned firms, WBENC for women-owned, NGLCC for LGBTQ-owned, Disability:IN for disability-owned, and NaVOBA for veteran-owned. A certification you earn for one buyer travels to all of them. The work to get certified is the same regardless of which corporation you're chasing, so do it once and use it everywhere.
If you're weighing which certifications fit your business and want the filings handled across multiple bodies at once, CertifyAll takes your information one time and prepares the applications, so you're not running each certifier's process separately.
A practical order of operations- Get your DUNS number and a one-page capability statement straight. Nothing moves without these.
- Register for GM Supplier Acceleration at gmsupplieracceleration.com. It's free and it's the right open door for a new supplier.
- Map your commodity to GM's Tier 1 suppliers and start pursuing subcontract work there. This is usually the faster path to real revenue.
- Get certified if you qualify, for the broader corporate market rather than GM specifically.
- List your business where corporate buyers look. A complete, searchable profile on a supplier directory means procurement teams can find you when they're sourcing your commodity, instead of waiting for you to find them.
GM is one large, slow, demanding customer. Building a business around landing it is risky even for strong suppliers. The owners who do best treat GM as one target inside a wider corporate pipeline, and they work several programs at once.
That's the honest play here. Register with GM, pursue its Tier 1s, and at the same time build relationships across other corporate supplier diversity and small-business programs that match what you sell. For a step-by-step on running that wider process, read how to get into corporate supplier diversity programs.
