Methods and systems for supply chain management in accordance with a state model. A supply chain management system includes a transaction state module within an inter-enterprise server assessable by trading partners. The transaction state module can define a state model which allows a trading partner to view a transaction and perform an action in accordance with a state of the transaction. The state model describes, in association with each state, which of the trading partners have visibility to the transaction and ability to perform an action. The trading partners can include consumers, retailers, distributors, etc. The transactions can include a forecast order, a purchase order, a billing, a product shipment, a payment, an invoice, a credit memo, a request for quote (RFQ), and a return material authorization (RMA). States of the transaction can include, for example, create, open, public view, private view, publish, commit, cancel, supersede, and the like.
