New Vendor Registration
To complete the vendor registration process, users can only
use Internet Explorer.
If you're new to MARTA (meaning you've never done business with us), you'll have to
register an account. Once your account is approved, you'll receive access to MARTA’s iSupplier Portal. This portal allows registered suppliers (including contractors, vendors and service providers) to conduct online transactions with MARTA.
Registering with MARTA is a two-part process.
- First, you'll apply for registration and upload tax documentation.
- Second, after receiving approval, you'll login to the iSupplier Portal and enter all of your vendor information.
After filling out your vendor information, you'll have full access to the iSupplier Portal and its admin features. Check out our
iSupplier training video and our
iSupplier FAQs (see below) to learn what all the platform offers.
