A local computer system that records information to facilitate a purchase transaction across a network. In one embodiment, the local system operates by receiving a request for billing information relating to a purchase transaction from a remote computer system. The local system then retrieves the billing information from its local store, and sends the billing information to a remote system. After the remote system completes the purchase transaction, the local system receives confirmation information from the remote system. The local system then records this confirmation information in the local store which enables a user of the local system to subsequently look up the confirmation information based on a purchase transaction identifier. Methods associated with the local computer system are also disclosed.
