    All vendors must register to do business with the District through PlanetBids.Vendors do not need to pay for a PlanetBids subscription or membership to register as a vendor or access solicitations for the Rialto Unified School District. The District will review all vendor applications in a timely manner and ensure all minimum requirements are met, including a recent copy of a W-9 Form and a complete Conflict of Interest and References form. 

    Changes and updates to vendor profiles will also be received through PlanetBids. Such changes include a change to the business name, address updates, remit to addresses, or change in W-9 information. 

    Vendors are responsible for maintaining their profile information up to date, including contact information and payment information (W-9). The District will not make changes to a vendor's profile unless the changes are made in PlanetBids by the Vendor. 

    Vendors shall not provide goods or services to the District without a signed Purchase Order. The District is not responsible for the payment of goods and services received without a signed Purchase Order. District staff requesting goods and services without a Purchase Order shall be held personally liable for the purchase. 

    Certain services may require additional documents such as a written agreement, employee background checks, or other documents deemed necessary to ensure the District and Vendor are properly covered.
