Creating an Account in the System

The process to register your firm with the District is a brief two step process.

First, you must create an account by filling in the information below. After registering your firm, you will be automatically directed to the Vendor Application form.

Important Note: If you received any form of notice from MMSD regarding this system, an account may have been pre-configured for you. Please look up your business to see if an account already exists. You can also check with Customer Service before registering to check for an existing account. If you are currently registered then your firm is already in the system.

Should you have any questions or require additional information, feel free to contact the Procurement Department via email at VendorHelp@mmsd.com or give us a call at (414) 272-5100. Thank you for your cooperation.
