Across all 50 states, over 33 state central purchasing offices and thousands of county governments, municipal utilities, public university systems, transit authorities, and K-12 school districts obligate approximately $1.6 Billion annually under NIGP 946-20, generating 510+ Bids active Invitations for Bid (IFBs), Requests for Proposals (RFPs), and informal quote requests each year. The NIGP taxonomy uses a hierarchical structure where the 3-digit Class (946) identifies the broad commodity or service family (Financial Services) and the 5-digit Class-Item code (946-20) pinpoints the specific service (cpa audit) deliverable. When state and municipal buyers post solicitations on portals such as Texas ESBD & ISDs, New York NYSCR, California Cal eProcure, and Pennsylvania eMarketplace, automated bid invitations are dispatched exclusively to vendors who have added NIGP Class 946 and Item 946-20 to their supplier registration profiles.
