Abstract: A transaction management system is described in which transactions between buyers and sellers are monitored to determine sellers qualifying for guaranteed or underwritten status. The sellers log details of their goods or services with the system which are then presented to buyers together with an indication of the seller's underwritten status. A buyer purchasing from a guaranteed or underwritten seller using the system obtains some form of compensation in the event that the seller does not deliver as promised. In a preferred embodiment, the system selects an alternative service or good for delivery to the buyer by the agreed date using the database of sales data. The sellers are advantageously graded into brands using historical transaction-related data.
