How these are counted: from this site's records only, so they grow as more states are researched. 4 states appear in the record in all, including replaced systems. Contract totals are approved ceilings or current contract values as the source states them, not money paid, and they are summed only where a state was researched in depth.

Every state system and contract action on this site that names Carahsoft. Figures are as stated in each source; follow the state link for the full record.

Every fact links to its source and carries a label: Public record Vendor claim Press / secondary
