Business-to-government
Business-to-government or business-to-administration is a derivative of business-to-business marketing and often referred to as a market definition of "public sector marketing". Which encompasses marketing products and services to various government levels through integrated marketing communications techniques such as strategic public relations, branding, marketing communications, advertising, and web-based communications.
Business-to-government networks provide a platform for businesses to bid on government opportunities which are presented as solicitations in the form of requests for proposals in a reverse auction fashion. Public sector organizations generally post tenders in the form of requests for proposals, requests for information, requests for quotations), sources sought and suppliers respond to them.
Government agencies typically have pre-negotiated standing contracts vetting the vendors/suppliers and their products and services for set prices. These can be local or national contracts and some may be grandfathered in by other entities, e.g., California's MAS Multiple Award Schedule will recognize the federal government contract holder's prices on a General Services Administration Schedule.
