Information for Vendors


As of June 1st, 2022, the State of South Dakota Office of Procurement Management will be migrating to the new ESM Source system. In order for you to participate in responding to our solicitations/bid events, you will need to be registered in the new ESM system as the legacy (eschoolmall/mercury commerce) system will be retired by the end of the year.

If you have not already registered with ESM, please click here to complete the process. Once you have registered, we recommend you review your Customers and Email Notification options located in your ESM Profile. This will allow you to customize the emails you receive from the system while controlling which bids you might want to be invited. If you do not choose to customize this information, you will receive emails from all Customers in ESM Sourcing System, not just the State of South Dakota Office of Procurement Management. 

If you have not previously registered for ESM Solutions, you may be presented the opportunity to map your individual supplier account with your companys existing record during registration. If you have an existing ESM Solutions account, you can select the Forgot Password link to reset your password.

If you should have any questions, please do not hesitate to contact Dawn Kassner at or you can reach out to ESM Customer Support at or call 877.969.7246.

Also, we have been informed that the automated emails from ESM ( may go to your junk mail, if this does happen, please add the email address to your address book to help ensure you receive all notices. Thank you!
