Abstract: A distributed computing system is disclosed that practically applies networked computing technology and machine-readable indicia to support traceability of products from providers to clients, the system comprising a plurality of distributed computers for connection over a network regarding a product identified by machine-readable indicia, for which a record is maintained in memory, and which is distributed through a supply chain that includes the provider, a transporting entity, an aggregation facility, a back haul provider, a distribution facility, and the client. The distributed computers include first, second, third, and fourth computers that cooperate with each other to support compliance with client rules and tracking of the order from the provider to the client through the participants in the supply chain via the machine-readable indicia and associations that are created in the memory to link the product with its passage through the supply chain.
