- You cannot "unpost" a manual bill. Instead, you have to reverse it.
- When a bill is unposted, all edits made to that bill are lost.
- Once a bill is unposted, a new prebill must be generated.
- Unposting can not be reversed. If you accidentally unpost the wrong bill, or need to reverse an unposted bill for any other reason, you must re-bill exactly as originally billed.
