Start by separating federal from state and local markets
Government contracting is not one centralized marketplace. Federal opportunities, state procurements, city and county solicitations, school and university purchases, and other public-sector opportunities can appear through different systems and follow different procedures.
A useful search process starts by deciding which market you are pursuing. Federal opportunity discovery should be treated separately from state and local discovery so that registration requirements, terminology, deadlines, and sources do not become mixed together.
