A parcel trace system for tracing parcels handled by a service provider for a plurality of clients. The system includes relay (30) adapted to communicate with the clients across the Internet and with a server database. The server database stores a plurality of parcel objects, each parcel object including a parcel identifier attribute and a parcel location attribute. The server database further includes a URL attribute for each client. A client database (80) includes a plurality of parcel objects, each object corresponding to a parcel being handled for the client and including a parcel identifier and a parcel location attribute. A client database controller (70) communicates with the relay, and across a second network, possibly the Internet with the client. The relay is responsive to a change in state of the parcel location attribute to relay the change in state of the parcel location attribute to the client database controller across the Internet. The client database controller responds to receipt of the change in state of parcel location to write the change of state to the client database. The client database controller is further responsive to parcel location requests from the client across the second network to return a location and a parcel identifier for any parcels requested by the client.
