The online statement feature reduces operational costs when subscribers adopt online statements instead of a printed one. Oracle Self-Service E-Billing can render a statement that looks similar to the paper statement. Taking advantage of the dynamic of the Web, Oracle Self-Service E-Billing can expand or collapse the amount of data displayed, drill down into details, show a more up-to-date statement, and display a previous statement.
