MARTA Procurement & Vendor Opportunities (iSupplier Bid Portal)
MARTA (Metropolitan Atlanta Rapid Transit Authority) is a major regional public transportation agency in Georgia. For vendors, its procurement source provides a centralized place to review solicitation outcomes (bid results) and to participate in transactions through MARTA’s supplier portal.
Why MARTA matters in the public-sector buyer landscape
MARTA operates a multi-modal transit system and manages ongoing procurement needs that can span services and support functions used to keep facilities operating. Its procurement source links procurement activity to a supplier portal environment where registered suppliers can manage their supplier profile and transact electronically. For vendors, that combination—public bid outcomes plus a centralized supplier portal—can make MARTA a practical buyer to monitor if you sell the kinds of goods and services MARTA purchases through its solicitation process.
Opportunity signals vendors can monitor on MARTA’s procurement source
MARTA’s bid portal includes a public Bid Results view, where procurement outcomes are published by solicitation (showing bid respondent names and pricing fields in the results table). The same bid portal also references additional areas such as Current Opportunities, Recently Awarded, Cancelled Opportunities, and Anticipated Procurement in the portal navigation. Vendors should verify what is currently posted for the procurement cycle by checking those sections from the procurement links available in the MARTA bid portal.

Vendor readiness steps for MARTA bidding and supplier engagement
To participate in solicitation responses, MARTA states that suppliers must be signed in to submit a response to a solicitation opportunity. MARTA also describes a two-part supplier registration process: (1) apply for registration and upload tax documentation, and (2) after approval, log in to the iSupplier portal and enter vendor information. MARTA further lists supplier portal capabilities that align with ongoing engagement: managing company profile information, viewing and submitting solicitation responses, acknowledging solicitation addenda, monitoring purchase orders/contracts/agreements, and handling invoices and remittances.
Capture and compliance strategy to avoid missed MARTA requirements
Use the procurement source navigation to keep continuity between opportunities and results—MARTA’s portal indicates that solicitation responses and addenda acknowledgements are handled through its supplier portal experience. Build internal controls around registration approval timing and portal access (since MARTA requires suppliers to be signed in to submit responses). When you receive solicitation addenda, acknowledge them through the iSupplier portal capability MARTA lists; this helps ensure your submission aligns with the most current requirements in MARTA’s process.
MARTA procurement links and vendor next steps
Start by reviewing the public procurement source entry points from MARTA’s bid portal navigation (Bid Results and the areas for current opportunities and other procurement status views). For vendor participation, complete MARTA’s iSupplier vendor registration process and then use iSupplier login to submit solicitation responses and acknowledge addenda where applicable. If you encounter bid or iSupplier issues, MARTA provides a customer service contact path and also lists an iSupplier registration assistance email for registration help; verify the latest support contact details on the iSupplier registration page before reaching out.
