A system and method of developing sales information for use in a buyer-seller environment is directed to providing one or more qualifiers which relate to a sales offering; determining value criteria, for each qualifier, to identify potential value of the sales offering; determining ideal buying criteria based on a competitive analysis; and developing the sales information from the value and buying criteria. The sales information, which can be a letter of understanding (LOU) or a buyer needs assessment, can be stored on a server and updated and accessed by one or more sellers. The updating can be an iterative process that is responsive to feedback about the sales information.
