Integrated Negotiation Engine

A computer-implemented method for producing a set of transaction terms for a transaction between a purchaser and a supplier, the method comprising:

• receiving supplier data and transaction data from one or more data sources via a communications network;
• storing the received supplier data and transaction data in a memory;
• accessing selected supplier data and selected transaction data from the memory;
• generating one or more simulations of the transaction from the selected supplier data and selected transaction data;
• and
• generating an interactive graphical representation of selected simulations of the one or more simulations in a graphical user interface.

An article comprising tangibly embodied computer-readable media operable to cause data processing apparatus to perform operations for producing a set of transaction terms for a transaction between a purchaser and a supplier, the operations comprising:

• receive supplier data and transaction data from one or more data sources via a communications network;
• store the received supplier data and transaction data in a memory;
• access selected supplier data and selected transaction data from the memory;
• generate one or more simulations of the transaction from the selected supplier data and selected transaction data;
• and
• store the one or more simulations of the transaction in a second memory.
