Become A SLAC Supplier
Partner with SLAC
SLAC partners with qualified suppliers and supports small business growth. Our procurement process follows federal requirements and SLAC policies, but we’ve made registering and getting started as simple as possible.
The process to become prequalified to do business with SLAC has three required steps:
- Register with SAM.gov. (All Awards status is required.)
- Submit the Prospective Supplier Information Form or the Construction Supplier Form.
- Initiate your PeopleSoft vendor profile.
After suppliers complete the Prospective Supplier Information Form(s) and initiate their vendor profile, and are approved by SLAC, they are added to our searchable database, which is accessible to all employees.
Prospective Supplier Requirements
You must complete all three required steps to become a SLAC Supplier.
The process is straightforward, but please remember that SLAC cannot issue contracts or purchase orders until you have completed all the steps.
For more detailed information, please see the section below, "Completing Supplier Registration."

Completing Supplier Registration
Below is detailed information on completing the three steps in SLAC’s supplier registration process.
You must complete all three steps to become a qualified vendor.
Register on SAM.gov
To do business with SLAC, your company must have a valid registration in the U.S. Government’s System for Award Management (SAM.gov). This federal requirement must be completed before any other steps in SLAC’s supplier process. All domestic suppliers are required to have an Active “All Awards” status.
SAM.gov registration is free and must be renewed annually. If you're awarded a SLAC purchase order or contract, your SAM registration must remain active for the full duration of that agreement.
IMPORTANT
SAM.gov Support
SLAC does not provide support with registering on SAM.gov. It is a federal website, not managed by SLAC. Find information on SAM.gov support.
No Fees Required
SAM.gov registration and renewal are always free. The U.S. Government does not charge any fees, and support is available at no cost. Read more about this in the FAQs below.

Submit a Prospective Supplier or Contractor Information Form
Once your SAM.gov registration is complete, the next step is submitting the appropriate form to be considered for SLAC’s Supplier Database. SLAC employees use this database to find qualified suppliers and contractors for projects and purchases.
Completing this form also allows SLAC’s procurement team to evaluate your qualifications. You’ll be listed in the database if approved, making your business more visible for future opportunities.
Choose the Right Form
SLAC qualifies prospective suppliers in two ways:
Prospective Supplier Information Form
Use this form if your company offers goods or services
Construction Supplier Information Form
Use this form if your company offers general contracting, preconstruction, or construction trade services.
You only need to submit one form, depending on the nature of your business.

SAM.gov (System for Award Management) is the official U.S. government website where businesses register to be eligible for federal contracts and grants.
All SLAC suppliers must have a Unique Entity ID (UEI). U.S.-based suppliers must also have an active SAM.gov registration (All Awards Status). These are required before a purchase order or contract can be issued.d
Registration is free, and support is available through the Federal Service Desk.

No, SAM.gov registration is entirely free. Be cautious of anyone offering to complete or expedite your registration for a fee or provide access to government contracts.
Read this article on SAM.gov for more information about fraudulent fees.
A Unique Entity ID (UEI) is a 12-character alphanumeric code assigned by SAM.gov to identify your business in federal systems. It replaces the older DUNS number and is required for all organizations doing business with SLAC. Both U.S.-based and foreign suppliers must obtain a UEI through SAM.gov, even if they are not required to maintain an active SAM registration.
A NAICS Code (North American Industry Classification System) is a six-digit code used by the U.S. government to classify businesses based on their products or services. SLAC requires suppliers to provide at least one NAICS Code to help identify your business’s industry and determine procurement eligibility, including small business status.
PeopleSoft is SLAC’s internal system that manages supplier records and processes payments. To receive payment for any work or contract with SLAC, you must be registered in PeopleSoft, regardless of whether you are a U.S.-based or foreign supplier.
Enrolling in PeopleSoft allows SLAC to:
- Issue purchase orders
- Process invoices
- Send payments via ACH or wire transfer
- Ensure tax and banking information is securely stored
This step is separate from submitting your Prospective Supplier Information Form and must be completed before any purchase order or contract can be awarded.
To enroll in PeopleSoft as a U.S.-based supplier, follow these steps:
- Obtain a Unique Entity ID (UEI) by registering your business at SAM.gov. Ensure your registration is active and has an “All Awards” status.
- Gather required documents:
- A completed W-9 form
- A bank document showing your account and routing numbers (This can be a letter from your bank or a signed company letter.)
- Visit the Supplier Registration Portal
- Click User Registration
- Select Register as U.S. Supplier and follow the prompts
- Enter your business information exactly as it appears on your W-9
- Provide your NAICS code, business type, and website (if applicable)
- Make sure to upload your W-9 form and bank document, and submit your information
Once submitted, SLAC will review your registration. You’ll be contacted if any additional information is needed.
To enroll in PeopleSoft as a foreign supplier, follow these steps:
- Obtain a Unique Entity ID (UEI) from SAM.gov. Foreign suppliers do not need an active SAM registration but must have a UEI.
- Gather required documents:
- A current and signed W-8 form
- A bank document showing your account and routing numbers, including:
- Account number and Bank ID (routing number)
- IBAN and SWIFT code
- Bank name, address, and phone (if available)
- Visit the Supplier Registration Portal
- Click User Registration
- Select Register as Foreign Supplier and follow the prompts
- Enter your business information exactly as shown on your W-8 form
- Upload your W-8 and bank document
- Provide your NAICS code(s), business website (if applicable), and indicate:
- Whether you will be providing goods, services, or both
- And, if services are performed in the U.S. or California
- Confirm that your form is complete and accurate, you have attached your W-8 and bank document, and submit your registration form.
Once submitted, SLAC will review your registration. If additional details are needed, you may be contacted.
SLAC’s Supplier Database is an internal tool that SLAC staff, researchers, and faculty use to identify prospective suppliers for goods and services. After review, businesses that submit the Prospective Supplier Information Form or Construction Supplier Information Form are reviewed for eligibility, and if approved, added to this directory.
The database helps SLAC employees search for and evaluate suppliers based on key criteria, including:
- Business name
- Goods or services provided
- NAICS codes
- Business type and socioeconomic status
- Capability statements and relevant qualifications
Each listing includes a detailed supplier profile with contact information, service descriptions, and—if applicable—construction licensure, bonding, safety records, and availability of audited financial records.
Being included in the Supplier Directory increases your business’s visibility to SLAC teams across the lab, but it does not complete your vendor registration or authorize payment.
You must register with SAM.gov and complete SLAC’s PeopleSoft Vendor System registration to complete the process.
Both steps serve different purposes and are required to do business with SLAC.
If approved, the Prospective Supplier Information Form or Construction Supplier Information Form adds your business to SLAC’s Internal Supplier Directory, making your goods or services visible to SLAC staff searching for qualified vendors. This step supports sourcing and vendor selection but does not authorize purchases or payments.
PeopleSoft enrollment is SLAC’s Vendor System. Without it, SLAC cannot issue purchase orders or process payments, even if you've been selected for a project.
To become a fully onboarded supplier, you must complete both steps after registering with SAM.gov and obtaining a Unique Entity ID (UEI).
PROCUREMENT TRANSPARENCY & COMPLIANCE
Stanford University operates SLAC for the U.S. Department of Energy (DOE), which oversees all purchasing activity. As a federally funded research and development center, SLAC must report all procurement activity to the DOE and comply with both federal regulations and internal SLAC policies. The Procurement Group manages supplier relationships, supports small business growth, and ensures all goods and services are acquired in accordance with these requirements.
Please note that completing the Prospective Supplier Information Form(s) does not guarantee a solicitation or contract award by SLAC or any affiliated entity.
