Duke University and Duke University Health System buy from thousands of vendors, from lab reagents and IT hardware to construction, food service, and professional services. If you want a piece of that spend, the first thing to understand is that Duke runs two related but separate systems: one for getting paid as an approved vendor, and one for being found and tracked as a diverse or local supplier. Knowing which door you are walking through saves weeks.
You cannot self-register first: the invitation modelHere is the part that trips up most new suppliers. You do not become a Duke vendor by filling out a form on your own. Duke uses PaymentWorks as its required vendor and payee registration platform, and registration is triggered when a Duke business unit sends you an invitation. A department, lab, or buyer has to want to work with you and initiate the invite. Once they do, you receive a link to register in PaymentWorks.
PaymentWorks is where you enter your tax information and banking details. Duke built the workflow this way for two reasons: payment security and electronic payment. Vendors enter bank account data directly into the secure portal so Duke can pay via ACH instead of mailing paper checks. The registration then routes to Corporate Accounts Payable and Procurement & Supply Chain Management for review.
The rule that matters: Procurement & Supply Chain Management must register every new vendor before an order is placed or any contractual relationship begins. No registration, no purchase order. So the practical sequence is: get a Duke buyer interested in your offering, they invite you into PaymentWorks, you complete registration, and only then can a PO flow to you.
This is the same pattern you will see across most large institutional buyers. If you have read our broader institutional procurement guides, the "get sponsored by an internal buyer, then formalize the relationship" model should look familiar. Duke is not unusual here. It is just well systematized.
The supplier diversity track: SupplierGatewayThe second system is where diverse and local businesses get visible. Duke's Supplier Diversity Program exists to build supplier relationships while supporting the growth of minority, women, veteran, small, and LGBTQ owned businesses. To run it, Duke partnered with SupplierGateway and operates a dedicated portal at dukesdportal.suppliergateway.com.
That portal does two things for you. It lets Duke track diverse-supplier spend metrics, and it surfaces RFP opportunities that you can respond to. Registering in the diversity portal is how you put your business on the radar of Duke's category buyers before they have ever heard your name, which is the closest thing Duke offers to a self-initiated entry point.
A point worth being honest about: registering in the SupplierGateway diversity portal is not the same as being an approved, payable vendor. The portal is for discovery and spend tracking. PaymentWorks is for getting paid. Most suppliers who succeed at Duke end up in both. Treat the diversity portal as marketing and the PaymentWorks invitation as the contract.
What Duke actually values: local and diverseDuke states plainly that it wants its supplier base to reflect its community, and that Supply Chain Management actively pursues partnerships with local suppliers in Durham and the surrounding counties. Geography is a real lever here. A diverse business based in the Research Triangle, or one with a Durham-area footprint, has a structural advantage in Duke's stated priorities that a vendor three states away does not.
On certifications, Duke's program covers the standard diversity categories: minority-owned (generally 51% owned by members of socially and economically disadvantaged groups), women-owned, veteran-owned, small, and LGBTQ-owned. The Duke pages reviewed describe these categories but do not name one single mandatory certifying body, so the practical advice is to hold a recognized third-party certification appropriate to your category rather than to chase a Duke-specific badge.
For minority-owned firms, that typically means an NMSDC affiliate MBE certification; for women-owned firms, a WBENC WBE certification; for veteran and LGBTQ firms, the corresponding national programs. If you are unsure which certification fits your ownership, our certification overview walks through what each one signals to a buyer like Duke and who issues it. You can also see which corporate and institutional programs recognize each certification in the program directory.
Duke Health adds a clinical layerIf you are selling into the hospital and clinical side, there is an extra step. Duke Health uses Vendormate for vendor credentialing for representatives who visit clinical and patient-care areas. That covers things like immunization records, training, and compliance attestations for people physically entering hospital space. It is separate from PaymentWorks registration and SupplierGateway diversity registration. If your product or service involves clinical access, expect to clear Vendormate before your reps set foot on a Duke Health unit.
A realistic plan to get startedSequence your effort instead of doing everything at once.
1. Get certified first
2. Register in the SupplierGateway diversity portal
3. Cultivate an internal sponsor
4. Complete PaymentWorks when invited
5. Clear Vendormate if you sell into Duke Health
Next stepThe thing that unlocks both Duke tracks is a current, recognized diversity certification. If you have not certified yet, or you are juggling which certifications your ownership actually qualifies for, CertifyAll handles the paperwork and submissions across the federal and state programs you qualify for, so you can spend your time courting Duke buyers instead of filling out forms. Once your certification is in hand, register in Duke's SupplierGateway portal and start watching for RFPs.
