Abstract: A method and computer-readable medium for managing order entry by a user via remote connection to an account database system of a service provider are provided. According to the method, order information is received from the user via the remote connection for an account of the user. Payment information is outputted to an external payment service for authorization of payment, and, if the authorization is successful, order information is received and written to a custom database of the service provider. A transaction record is then written to an account transactions file of the service provider, thereby triggering execution of an accounting program for posting the order information to the user's account and to records of the service provider. The updated order information may then be outputted to the user.

Abstract: A method and computer-readable medium for managing an account balance of a user via remote connection to an account database system of a service provider are provided. According to the method, payment information is received from the user via the remote connection for a selected invoice of an account of the user. The payment information is outputted to an external payment service for settlement of payment, and, if the settlement is successful, authorization and settlement data are received from the external payment service and written to a payment file of the user. A transaction record is then written to an account transactions file of the service provider, thereby triggering execution of an accounting program for posting the authorization and settlement data to the user's account and to financial records of the service provider. The updated invoice information may then be outputted to the user.
