A federal contractor is defined by U.S. Code "to include any person who enters into a contract with the United States or any department or agency thereof for the rendition of personal services and whose compensation is paid in whole or in part from funds appropriated by Congress." 
Often, this "means an entity that has submitted the successful bid or proposal in response to a competitive acquisition solicitation."  However, federal contracts are also awarded in the case of non-competitive bid and/or sole source contracts.
