Abstract: The present invention provides a comprehensive, integrated, computerized system for facilitating transactions in goods or services. The system is capable of facilitating transactions from early or initial stages, such as an electronically proposed purchase order, through to later or final stages, such as payment on an invoice or invoices relating to the transaction. The system is integrated to include the participation of various providers of services ancillary to transactions, such as guarantors, insurers, and shippers. The system may allow sellers or buyers to electronically propose amendments and counter-amendments to, and to amend, through mutual agreement, a purchase order agreement. Any amendments are accounted for in later stages of the transaction facilitated by the system.
