Most guides to selling into a Fortune 500 pharma company stop at "fill out the form." With Eli Lilly, the form is real and it's open to anyone, which is exactly why filling it out accomplishes almost nothing on its own. The registration is a database entry. The decision to buy from you happens somewhere else entirely. This walks through both: the mechanical registration, and the thing that actually gets you a contract.
What Eli Lilly buysLilly is a roughly $40B+ revenue pharmaceutical company headquartered in Indianapolis, and its spend reflects that. The obvious categories are direct: active pharmaceutical ingredients, lab consumables, clinical trial services, packaging, cold-chain logistics. The larger and more accessible bucket for most diverse businesses is indirect spend — facilities and construction, IT and software, marketing and creative, professional services, staffing, travel, and the long tail of operational vendors that keep a global manufacturer running.
If you're a smaller firm, the indirect side is where you start. Lilly does not need a 12-person consultancy to make insulin. It does need printers, translators, event producers, data analysts, electricians, and dozens of other services it would rather not staff internally.
How registration actually worksLilly runs an open application through its Online Supplier Form (OSF) at prospectivesupplier.lilly.com. There's no invitation gate to submit it. Anyone can register their company, capabilities, and diversity classifications.
Be clear-eyed about what that buys you. Lilly's own language is direct: "If there is a need for your services, someone from Lilly will contact you." Translation: the OSF is a searchable supplier database, not an application that triggers a review. You're making yourself findable to a category buyer who already has a need. You're not getting in a queue that someone works through.
Once Lilly decides to onboard you, the relationship moves onto SAP Ariba (the SAP Business Network). Lilly uses it for sourcing events — RFx and reverse auctions — and for contracts. When onboarding starts, you'll get an email inviting you to connect with Lilly on the network and complete the formal registration there. So the practical sequence is: OSF first (you raise your hand), Ariba second (Lilly pulls you in). Don't expect to skip to Ariba on your own.
How to actually get noticedSince the form is passive, your job is to make a buyer want to search for you and find you specifically. A few things move the odds.
Get your capabilities described in the buyer's vocabulary, not yours. A category manager searches for "bilingual patient-education content" or "GMP facility electrical contractor," not "innovative communications partner." Write your OSF profile and your one-page capability statement in concrete, category-matched terms with NAICS codes attached. If you don't have a tight capability statement yet, our free capability statement builder and supporting tools will get you a usable one.
Be present where Lilly's supplier diversity team already looks. Lilly works through third-party certifying organizations to verify diverse status, and it participates in the certification ecosystem the way most large pharma buyers do. Showing up in NMSDC and WBENC matchmaking and conference settings puts a face on the database entry. A profile a buyer can find plus a person they've met is a very different position than a cold form.
List yourself in the public directories diverse-supplier scouts actually browse. A complete profile in our diverse supplier directory is one more surface where a Lilly category buyer or one of its primes can find you without you cold-emailing anyone.
The diversity-certification angleThis is where Lilly is unusually specific, and where most applicants leave value on the table. Lilly's Supplier Development program recognizes a defined set of classifications, and getting certified into the right one is what lets a buyer filter for you and report your spend.
The classifications Lilly recognizes include:
- Small Business Enterprise (SBE) and Small Disadvantaged Business (SDB)
- Woman-Owned Small Business (WOSB) — via the SBA or WBENC
- Veteran-Owned Small Business (VOSB) and Service-Disabled Veteran-Owned Small Business (SDVOSB)
- Veteran Business Enterprise (VBE)
- HUBZone business
- Disability-Owned Business Enterprise (DOBE)
- Under-Leveraged Business (ULB) — Lilly's own proprietary classification for small and underrepresented firms that don't fit the standard buckets
Notice what's load-bearing here: Lilly verifies status through outside certifiers. A self-declared "minority-owned" checkbox is weaker than a current NMSDC MBE certificate or a WBENC WBE certificate sitting on your profile. If you're minority-owned and not yet certified, the NMSDC route is usually the highest-leverage credential for corporate pharma buyers — our NMSDC certification guide walks through eligibility, cost, and timeline.
One practical note: get certified before you chase the relationship, not after. Certification can take weeks to months, and a buyer who finds you mid-application can't report you as diverse spend yet. The certificate is the thing that makes you countable, and countable is what their internal targets reward.
The Tier 2 side doorHere's the path most small firms miss. Lilly runs a Tier 2 reporting process, which means it tracks and credits diverse spend that flows through its prime suppliers, not just the diverse vendors it pays directly (Tier 1).
What that means for you: you don't have to win a direct Lilly contract to do business connected to Lilly. If you subcontract to one of Lilly's existing large suppliers — a facilities firm, a staffing agency, an IT integrator, a marketing holding company — that prime can report your work as Tier 2 diverse spend toward Lilly's goals. Primes are often actively looking for certified diverse subcontractors precisely because their contracts with companies like Lilly carry diversity-spend expectations.
So a realistic plan for a small certified business is often two-pronged. Register on the OSF for direct visibility, and separately go find the primes who already hold Lilly contracts in your category and pitch them on the Tier 2 value you create for their Lilly relationship. The second path frequently closes faster, because you're solving a reporting problem the prime already has.
A grounded next stepEli Lilly's program is open, specific about certifications, and built on a Tier 1 plus Tier 2 structure that rewards certified firms who make themselves easy to find and easy to count. Register through the OSF, get the certification that matches your ownership, and work both the direct and Tier 2 angles.
Lilly is one buyer. If you want to see which other corporate programs recognize the same certifications and run comparable open registrations, our corporate program directory lets you line them up and apply your certification across several at once.
