This section is designed to provide information for individuals and entities (“suppliers”) providing goods or services to, or being reimbursed by, Yale. It also provides information for Yale individuals and departments who engage with suppliers for these purposes.

To engage with this topic, consult the selection of resources in this section. For additional support, connect with the contacts or submit an inquiry to the appropriate area listed at the bottom of this page.

Departments who require information to navigate the Supplier Set Up and Change Request process should refer to the Procurement Toolkit. Departments who require support in the Sourcing/Buying process should submit a support request via the Purchasing Intake Portal.

To become a supplier for Yale University, you should start by emailing supplier.development@yale.edu about the Yale University Supplier Registration & Questionnaire form. Once your questionnaire is reviewed, you may be invited to register through the Yale Supplier Gateway, where you will receive login credentials and instructions to complete your registration. During registration, you’ll need to provide required documentation such as IRS tax forms (W-9 for domestic, W-8BEN for international), business contact information, bank account verification, and, if applicable, a certificate of insurance.

For additional tools and resources, refer to the Supplier Set Up and Change Request process. If you have questions or need support, contact the Finance Support Center (FSC) at askfinance@yale.edu.

Once the completed Form 3401 FR.10 Supplier Gateway – Contact Form is received back from the Supplier and reviewed for accuracy and completeness, the requestor may proceed with sending an invitation through the Yale Supplier Gateway by following the steps below:

Steps to Invite a Supplier:

  1. Log in to the Yale Supplier Gateway.
  2. Select “Invite Supplier.”
  3. Complete all required fields marked with a red asterisk (*).
  4. Click Submit to send the invitation.

Requestors who wish to track a Supplier’s progress after the invitation has been sent can do so by accessing the “My Suppliers” section within the portal.

Important:

If the system times out before the invitation is submitted, progress is automatically saved. Users can search for the saved invitation upon logging back in to resume.

If a Supplier does not log in using the initial invite, after 21 days the Supplier record will be deleted from the system. If you still require the supplier, you will need to send a new invitation.

After a Yale community member submits an invitation via the Yale Supplier Gateway, the prospective Supplier receives an email containing login credentials and step-by-step instructions to complete their registration.

  • Communication of Yale’s Purchase Order Terms & Condition

Standard Payment Terms are Net45

Yale’s preferred disbursement option is ACH.

  • All domestic suppliers are encouraged to sign-up for ACH to ensure fast and secure payment.
  • International Suppliers are encouraged to sign-up for wire payments. The information a Supplier needs to provide for international wire transfers depends on the country and bank. When entering banking information into Supplier Gateway, Supplier Gateway will outline to the Supplier what information will be needed.
  • International Suppliers are encouraged to sign-up for wire payments.
  • Virtual credit card payments are available for domestic and international suppliers who meet specific criteria.
  • Payment by check is available, but strongly discouraged; payments rendered by check will result in a longer turn-around time for payment and expose both suppliers and Yale University to fraud.

The most efficient method of verifying the status of invoices/payments is through Yale’s Supplier Portal (iSupplier).

To gain access to the Supplier portal, please fill out the Supplier Portal Disclaimer form and send to askfinance@yale.edu with “Supplier Portal Disclaimer” in the subject line of the email.
