After Billing a charge how can I mark it so it will not be billed again?

In order to avoid billing the same charge more than once, mark it as billed. Right click on the Charge > Mark as Billed, or enter the charge details and click on the Mark as Billed button.

If you don’t see the Mark as Billed option, this is because the charge’s status is Not Billable. To bill this charge, modify its status to Billable.
