On occasion there could be payments which fail to post in Opera. This can happen even though the payers card was charged. This error most commonly occurs when the reservation is left open at the property when the payment is attempted.
To balance Opera & your bank account, the property must manually post the payment into Opera.
To do this, you need manual posting credit card types set up.
If they are not already existing in your PMS, please take the following steps:
Opera configuration < cashiering < payment types < add new < manual VISA.
(repeat for other credit card types).
If you do not have access to these screens in Opera, you will need to reach out to Opera Support to have them created.
