On the Billing page of a Customer Account, find the Charge (i.e., Tuition, fee, etc.) in the Transaction History (NOTE: Charges are in red). Click the three dots (to the far right) on the Charge.
Charge Added in Transaction History
If the Charge was added directly to the Transaction History (that is, it is NOT part of an Invoice), then the Edit option will appear.
Click Edit. In the new window that opens, click Delete transaction to delete the transaction (Charge):
Charge as part of an Invoice
If the Charge is part of an Invoice, after clicking on the three dots beside the charge, the option "Go to Invoice" will appear.
This will take you to the Invoice this Charge is on. On the Invoice, you can then click Edit. In the new window that opens, click Delete transaction to delete the transaction (Charge):
Once the Charge is deleted, it will no longer show on the Transaction History or on that Customer's Invoice.
