Registering in eVA
Prince William County Public Schools uses Virginia's eProcurement Portal (eVA) for issuing formal solicitations. Registering with eVA allows vendors to select commodity codes that represent the goods or services for which you would like to receive notices of current bid opportunities. Once your business is registered in eVA, you will automatically receive electronic notices of bid and solicitation opportunities that are relevant to the commodity code(s) you selected during registration.
