A system to automatically qualify a party to participate within a computer-based commerce transaction is described. The system receives, from a first party, item information relating to an item to be offered for sale. The system generates user interface information including criterion information and communicates a user interface, over a network, to a client machine. The system receives from the client machine and from the first party at least a portion of the criterion information. The system parses to identify and extract at least one criterion from the criterion information that is automatically satisfied by a second party to qualify the second party to bid on the item via the computer-based commerce system.
