  • SIGMA VSS: Doing business with the State

    The State of Michigan has upgraded its financial and business processes to a new system, SIGMA

    SIGMA improves the way Michigan performs financial activities, including budgeting, accounting, payments, and business and grant opportunities. SIGMA Vendor Self Service (VSS) improves working with vendors, payees and grantees, replacing Contract & Payment Express (C&PE) and Buy4Michigan.

    Key Items

    • You will continue to get paid regardless of whether you have claimed your SIGMA VSS account. 

    • You will need to claim your SIGMA VSS account to respond to business opportunities.

    • Quick reference guides are available below to assist you with claiming your VSS account, registering as a new vendor with the state, or seeing your payment information.

    • Additional user information, along with instructions on how to claim and validate your account, are provided on the SIGMA VSS home page access on the link below. 

    If you had an active account in the C&PE and were converted to the user-friendly SIGMA VSS, you should now claim your VSS account.  Additional user information, along with instructions on how you can claim and validate your account, are provided on the SIGMA VSS home page.
