What does the "dumb room" in the hotel cashier system mean?

Virtual room number/front desk work account/dumb room /PM room can be regarded as a concept, that is, the hotel front desk is an account for non-residential rooms, which is generally used for auditing account adjustment.

You can also add one more account, that is, the unpaid account cannot be linked to accounts receivable because there is no relevant agreement, but guests can also make a fake room-a dumb room to hang accounts. Now there are many system supports, such as temporary account or single room check-out, but the room account cannot be settled, which is also the same reason. These accounts need auditors to supervise the front desk to clean up regularly. If there are many such accounts, the front desk staff should be required to provide details of the projects that should be closed every week and explain the reasons. In the meantime, the financial department will supervise them. If an account is not closed regularly, financial follow-up can be taken.
