Most supplier relationships are established within the departments on the four CU campuses. To be an established supplier, you must be invited by a CU department.
CU Supplier Portal
The CU Supplier Portal is available through the University's eProcurement system, CU Marketplace. As an external supplier, register in the CU Supplier Portal to do the following:
- Register online to become a supplier with CU (this is done by invite only).
- Manage supplier information, such as addresses, contacts, and diversity classification
- View and respond to University solicitations on CU's BidNet Website.
- Submit invoices and view invoice status online (this access replaces the need to submit to apinvoice@cu.edu or to contact the University for invoice status information). Available Late 2024
Individual Payees
If a department wishes to issue you an Honorarium, you will receive an invitation to register as an Individual supplier in the CU Marketplace. Individual suppliers are a condensed registration that is not required to provide as much information as a Company or an Independent Contractor that receives a Purchase Order. Follow the registration steps noted here (Individual Registration Knowledge Article) and in the video below:
Companies/Organizations and Independent Contractors
If your company/organization is working with a CU department, or you are working under a Scope of Work, you will need to complete a Company/Independent Contractor registration. This registration collects more information, such as what types of goods/services you will be providing the University, Small Business designations, and more. Follow the registration steps noted here (Company/Independent Contractor Knowledge Article) and in the video below:
