If you detected that rent charges were not made on some rooms, check if they already had rent charges applied on that day (manually), in some cases it will be the full rent and in others the VAT corresponding to the rent.
In the latter case, these VAT charges correspond to rentals of previous days but the VAT are generated each time a user enters the account and are automatically eliminated when the user leaves the account with the "Exit" button, the problem is that some users do not leave the account management option with the "Exit" button, but directly selecting another option from the menu and this has the effect of leaving the VAT charges alive, it also leaves the active signal that a user is using that account, generating confusion to the other users when they try to use that account since it gives them the message that another user is using the account when that is not true.
In the particular case of the rooms that were charged the rent manually today and that are still in the hotel tonight, the system will not apply the automatic rent because it will detect that they already have a rent applied, therefore they should apply it manually, preferably before running to the audit so that it is reflected with the correct date.
