How To Submit An Invoice

An individual or company not yet registered as a Columbia University vendor must be invited by a Columbia University employee to register as a new vendor via PaymentWorks. Those registered as active Columbia vendors prior to the implementation of the PaymentWorks system do not need to register via PaymentWorks. However, those who need to update information or are not already registered as vendors must complete the PaymentWorks onboarding process.  

  • Vendors/suppliers who submit an invoice to The University Seminars for the first time will need to complete the vendor onboarding process via PaymentWorks. The University Seminars Administrative Assistant, Giran Ceballos, will initiate the invitation to PaymentWorks upon receipt of invoice. New Vendor profiles are reviewed and approved by the Finance department. The approval process can take up to 4 - 8 weeks.
  • View and download the Creating a PaymentWorks Account and Registering as a Columbia University Vendor job aid. 
  • The Finance department will review and approve the Vendor Profile via the PaymentWorks portal. This review/approval process can take up to eight weeks. Our Administrative Assistant, Giran Ceballos, will monitor this process closely.
  • Once the New Vendor Registration is approved and a vendor profile is created in the University's accounting system, our Administrative Assistant will process the invoice for payment. Payment is contingent on approval from Columbia University's auditing department. This approval process can take an additional two - four weeks to complete.

All invoices can be sent via email to Gesenia Alvarez ([email protected]) for processing and must include all of the following:

    Name, address, phone number, and email address (name and address should match your CU vendor profile information and/or your PaymentWorks application.)
