Prospective Suppliers

Thank you for your interest in doing business with Capital One. Please complete the registration process in Ariba® Discovery™ to be considered for participation in our request for proposal process; we exclusively use Ariba® Discovery™ to capture all inquiries from potential suppliers.


  • If you become an active supplier to Capital One, you will need to complete a separate supplier setup process. Registering on Ariba® Discovery™ does not set up your company for invoicing and purchase orders.
  • If you are a current supplier to Capital One, you do not need to complete the registration process.
  • If you previously registered on Ariba® Discovery™, you do not need to register again.
  • Registration does not constitute a commitment to any level of business with Capital One. We will be in touch only if there are opportunities that our business needs, and at our sole option. No contact means there are no opportunities for products and services in your category at this time.

Capital One is committed to ensuring all suppliers have access to our supply chain. We specifically register and track Diversity suppliers using a different tool. If your firm is a certified diverse supplier, please register as a new Diversity Supplier.
