Bidders / Suppliers Registration

iSupplier System

The system is a shared database with Loudoun County Public Schools. iSupplier allows multiple users to access the same company profile if needed such as representatives for government and non-government sales.

• Allows prospective (new) bidders and current suppliers to register as a source for formal procurements and small purchases as well as benefiting from additional online capabilities.
• Required information to register a company profile can be found on the iSupplier Registration and Login page
• During the registration process, a commodity code(s) must be selected to indicate the products and services you provide. Register for all commodity codes related to your business.
• Once approved, the company’s self-service profile becomes a registered supplier record.

Registration Benefits

Suppliers once registered receive solicitation notices as an invite. Suppliers have the ability to view solicitations, bid online, view orders, and track payments issued to the supplier. In addition, suppliers can maintain their company profile information and assign online access to multiple users.

Sourcing & Online Bidding

Sourcing is used to send notices to registered (bidders) suppliers based on the applicable commodity codes selected for a solicitation. Registered Suppliers will login to iSupplier to access the Sourcing home page and have the ability to view a solicitation and bid online. Once a solicitation is awarded, the suppliers who bid will receive notice of the award.
