E-commerce methods and systems that support the diversity of goods traded in the online open market by using a supplementary order form

摘要

Provided are a method and system that can support goods transaction diversity and extend and promote electronic commercial transactions by improving a process in which a buyer provides a seller with necessary supplementary order information for ordering goods or services that are difficult to trade in an on-line mode, receiving all supplementary order information from the buyer through a supplementary order form registered in an on-line open market without exchanging additional information between the buyer and the seller in an off-line mode in relation to the sale of goods or services requiring the supplementary order information, and allowing the seller to efficiently prepare and deliver the ordered goods or services.
