iSupplier Vendor Registration



**NOTICE**

MARTA's Department of Technology is advancing to the next stage of Project Everest. As MARTA prepares for the Authority-wide launch of Oracle Cloud Enterprise Resource Planning (ERP) on January 21, 2026, we want to ensure that you are aware of and prepared for the upcoming cutover.

 

Please be advised that MARTA’s self-managed supplier portal (iSupplier) will be temporarily unavailable beginning Monday, January 5, 2026, at 5:00 p.m., at which time access will be removed. This planned outage is necessary to support our transition to an upgraded procurement and supplier management system designed to enhance functionality, security, and overall user experience. During this downtime, suppliers will be unable to submit or update information through the iSupplier portal.

 

We encourage you to plan accordingly and complete any time-sensitive activities prior to the system shutdown. Access to the iSupplier portal will be restored at 11:00 a.m. on January 21, 2026 and training documents will be available on the iSupplier site.

 

We appreciate your patience and cooperation as we complete this important upgrade and work to better serve our supplier community.
