Vendor totals add up the award records RFPFinder holds: federal contract awards from USAspending.gov for the agencies and codes behind open notices, and state and local awards from open-data contract registers and purchase-order files. They are not a vendor's complete government revenue, and a register that lists a contract ceiling or repeats a contract can overstate spend. Names are grouped across spellings ("Corp" and "Corporation"); each award links to its source record. Subcontracts are prime contractors' subaward reports on USAspending.gov for the prime awards behind the same agencies and codes, and GSA Schedule contracts come from GSA eLibrary's MAS contractor list; both are matched to vendors by name.
