Register as a City Supplier (Vendor)

Do you have services or products you think would be useful to the City of Miami?

Registering as a supplier will allow you to receive purchase orders, track invoices and payments, update your company profile information, and add users to your account. You will not be awarded City business unless you are registered as a City vendor.

Note:  It is the suppliers responsibility to ensure that the information in the supplier profile, including email addresses, are up to date to ensure POs are delivered correctly through our ERP system, and that the Certificate of Insurance (COI) is renewed prior to expiration (if required). 


Gather Your Information.

Make sure you have the following information:

  • Company Name
  • FEIN (Federal Employer Identification Number) or SSN (Social Security Number)
  • An email address that will remain valid/live, even if an employee leaves, and/or an email address that is reviewed by more than one person

Register on the City’s iSupplier Platform.

Tips while registering:

  • We recommend listing a company email, rather than a single person
  • Have all of the information available and on hand to complete the application
  • Ensure you hit submit once complete 
  • Do not forget to submit your W9, as any application without a W9 submitted will not be processed
