# Undo Processing
It may be necessary to undo billing processing due to numerous errors that must be corrected (you must also undo the billing run in the case of a selected accounts billing). Any information created by the billing processing will be removed. Select this option any time before selecting Close.
* Select Undo Processing from the Account Billing menu to display the Account Billing Undo window. All of the open billing runs are displayed.
* Select the billing runs that should be undone (by selecting the appropriate checkbox).
* Click Continue. At this point, you will be prompted about whether the billing run should be undone.
* Click Yes to continue. All charges created by the billing run will be reversed, and the undo process will produce the Account Billing Undo report, which lists the control totals for the canceled billing.
