A server acts as the hub of a collaborative commerce system. Suppliers of goods or services self publish information to the hub. Buyers are able to query the hub for product and service availability, price etc. Buyers are able to integrate real time multi product and multi service orders from multiple suppliers, carriers and field serve providers and thus secure available goods as well as the delivery and installation of those goods from the records available on the hub. Once an order is complete to the buyer's satisfaction, the order is transmitted to the hub. The hub then transmits the appropriate information to the relevant suppliers, carriers and installers as required. The system also provides for a system of virtual partitioning of a supplier's inventory.
