How to become an ExxonMobil supplier: registration, supplier diversity, and the realistic on-ramp

ExxonMobil reported more than $6.8 billion in spend with diverse U.S. suppliers in 2024, against a public goal of $6 billion a year by 2025. Those are the kinds of numbers that make a small business owner want a foot in the door. The good news: getting into ExxonMobil's supplier diversity database is free and takes an afternoon. The honest part: registering is the easy step, and it is not the same thing as winning a contract.

This guide separates the two. First, how to actually register, in the right portal, with the right documents. Then, the part most articles skip, what moves you from a profile in a database to a purchase order.

ExxonMobil runs two different supplier systems

This trips people up constantly, so get it straight before you start. ExxonMobil sources through more than one system, and the one you use depends on where you are in the process.

SupplierOne is the supplier diversity database. It is ExxonMobil's branded front end for the Supplier.io platform, which a thousand-plus corporations use to find and verify diverse and small suppliers. Registering here is free, open to any business, and it is how procurement professionals discover you during market research. If you are a diverse or small business and want to be found, this is your first stop.

The ExxonMobil supplier portal, running on ServiceNow, is the transactional side. This is where companies that are already doing business with ExxonMobil manage onboarding, invoicing, payment status, and purchase orders. You generally land here after a buyer has decided to work with you, not before. Behind it sit systems like SAP Business Network for shipping and invoicing, and Taulia for early-payment options.

The mistake is treating the ServiceNow vendor portal as a way to get hired. It isn't. It is plumbing for an existing relationship. The discovery work happens in SupplierOne and in the conversations that come after.

What ExxonMobil counts as a diverse supplier

ExxonMobil recognizes suppliers that are at least 51% owned, managed, and operated by people who are ethnic minorities, women, people with disabilities, U.S. military veterans, or LGBTQ, plus small businesses as defined by the U.S. Small Business Administration. That is the same ownership bar most corporate programs use.

What carries weight is third-party certification. ExxonMobil's supplier diversity page points to five certifying bodies:

• National Minority Supplier Development Council (NMSDC) for minority-owned businesses (MBE). ExxonMobil has been a member since 1980.
• Women's Business Enterprise National Council (WBENC) for women-owned businesses (WBE). ExxonMobil was a founding member in 1997 and sits in WBENC's America's Top Corporations Hall of Fame.
• National LGBT Chamber of Commerce (NGLCC) for LGBTQ-owned businesses (LGBTBE).
• Disability:IN for disability-owned businesses (DOBE).
• National Veteran Business Development Council for veteran-owned businesses (VBE).

Outside the U.S., ExxonMobil references WEConnect International for women-owned businesses. Self-certification counts toward visibility in the database and toward the company's stated spend goals, but a national certification from one of those bodies is what gives a buyer confidence and what lets your status flow into the corporate reporting that supplier diversity teams answer for.

If you don't hold one of those certifications yet, that is worth fixing before you chase a relationship, because it is the credential the program is built around. Our corporate programs directory shows which certifications each large buyer recognizes, so you can match the credential to the buyers you actually want.

How to register in SupplierOne

The registration itself is short. Pull these together first so you aren't stalling halfway through:

• Legal business name and address exactly as they appear on your tax and certification records.
• Your federal tax ID (EIN).
• Your diversity certification documents, the actual certificate PDFs from NMSDC, WBENC, NGLCC, Disability:IN, or the veteran council, so you can upload them.
• Your NAICS codes and a tight description of what you sell. Oil and gas procurement is specific; a buyer searching the database is filtering by capability, so vague descriptions get skipped.
• A capability statement if you have one. It is the document a procurement contact will ask for first.

Then:

1. Go to ExxonMobil's supplier diversity page and follow the link to register in SupplierOne. Registration is free.
2. Create your profile. Note that ExxonMobil's diversity system allows only one user logon per supplier, so use a shared, durable email rather than one person's address.
3. Enter your business details, NAICS codes, and capabilities. Be specific and use the keywords a buyer would search.
4. Upload your certification documents. This is the step that separates a serious profile from a placeholder.
5. Keep it current. The database is described as the first stop in supplier searches, which only helps you if your information is accurate and your certifications haven't lapsed.

That is the whole registration. An afternoon, no fee.

Why registered isn't hired

Here is the part that matters. A profile in SupplierOne makes you findable. It does not put work in front of you. ExxonMobil's procurement is concentrated in capital projects, drilling and production services, refining, chemicals, logistics, MRO, and professional services, and most of that spend moves through established suppliers and competitive sourcing events.

To turn a registration into revenue, three things have to be true.

You fit a category ExxonMobil actually buys. A safety-gear distributor, an industrial-services firm, a staffing agency, a software vendor, these map to real procurement categories. If your offering doesn't, no database listing changes that. Read ExxonMobil's procurement pages and be honest about where you fit.

You can pass prequalification. Large operators run technical, financial, and safety screening before they buy, especially for anything that touches a facility or a worksite. Insurance, safety record, financial stability, and relevant past performance get checked. Get those in order before you pitch, not during.

You get in front of a human. Databases feed discovery, but contracts come from relationships. Supplier diversity teams attend NMSDC and WBENC events, regional council matchmakers, and energy-sector procurement fairs. That is where a buyer with a real need meets a supplier who fits it. Showing up certified, prepared, and specific beats a cold profile every time.

The Tier 2 path most owners overlook

If you can't land ExxonMobil as a direct (Tier 1) supplier yet, there is a side door. ExxonMobil runs a second-tier supplier diversity program, which asks its large prime suppliers to track and report their own spend with diverse subcontractors. That means the engineering firm, the logistics company, or the integrated-services contractor already holding an ExxonMobil contract has its own reason to bring diverse subcontractors into the work.

For a newer or smaller business, subcontracting to one of ExxonMobil's primes is often a faster, more realistic on-ramp than a direct award. You build a relationship, you get real energy-sector past performance, and you become a name the prime can point to in its Tier 2 reporting. Then a direct relationship gets easier. When you research the corporate programs directory, look at the large engineering and oilfield-services firms too, not just the brand-name end buyer.

A note on the 2025 climate

Corporate diversity language shifted in 2025. In early 2025 ExxonMobil softened references to diversity in its corporate 10-K filing, leaning toward terms like meritocracy and professional development, in line with a broader pullback across large U.S. companies. At the time of writing, the procurement-side supplier diversity page still used supplier diversity framing and still pointed to the same certifying bodies. The practical takeaway: the certifications and the supplier database are still the mechanics buyers use, but program emphasis and public language can move. Verify the current program on ExxonMobil's own procurement pages before you build a plan around it, and don't bet your pipeline on a single corporation. Spread your certifications across multiple buyers.

Your next three moves

1. Get certified, or confirm your certification is current, with NMSDC, WBENC, NGLCC, Disability:IN, or the National Veteran Business Development Council. This is the credential the whole program runs on. If you're juggling multiple applications across agencies and bodies, CertifyAll handles the filing in one pass instead of one portal at a time.
2. Register in SupplierOne with complete details, the right NAICS codes, and uploaded certificates.
3. Build the rest of your profile so a buyer who finds you reads you as a serious vendor. A public, polished supplier profile and a tight capability statement do more than a database listing alone.

ExxonMobil is one large buyer with a real supplier diversity track record, but it is one of dozens. The smarter play is to register where you fit, certify once, and target the buyers whose categories match what you sell. Start with the corporate programs directory to see which Fortune 500 programs recognize your certification, then work the ones that buy what you make.
