SIGMA VSS: Doing business with the State

  • SIGMA VSS

    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.
