NYS Comptroller


Update Vendor Information and Access

As a New York State vendor, you must ensure your business information is accurate and up to date with the Office of the New York State Comptroller (OSC). You have the option to do so online 24/7 through the Vendor Self-Service Portal or manually by mailing in forms AC-3326-S or AC-3327-S, which can take up to eight weeks to process. Additionally, you can create and manage Vendor Self-Service user log-ins for others in your company, allowing those users to access your vendor’s information.

Update Address and Contact Information

Maintain address and contact information by logging in to the Vendor Portal in SFS. You can both update and add addresses and contacts through the Vendor Portal. Your changes will take effect immediately.

Please note that you can’t update the default remittance address or change the primary contact through the Vendor Portal. Instead, you must file the paper form AC-3326-S to update the default remittance address and the paper form AC-3327-S to change the primary contact. Updates made to primary contact information, where the primary contact will remain the same, can still be made through the Vendor Portal (for example, updating a title due to a promotion, phone information due to a move).

  • designate guest roles for other employees to log into the account
