First, it is necessary to separate two terms, Total and Total Due (or Balance Due).
Total - this is the sum of accommodation, sales and surcharges, the total or charges of a reservation. It changes when you edit reservation price, add a coupon, sell an item or with the surcharge but not when you take payment.
Total Due or Balance Due - the remaining amount to be charged. This corresponds to the Total minus what was already paid.
You can Adjust Balance Due manually if you want to change it without any transaction. You can do it from two places:
- Dropdown reservation menu:
- Adjust Balance button in the Payments tab:
When clicking on Adjust Balance, you will be able to set the balance to the desired amount:
Or just Set 0 and Close:
The information about this action will appear in the reservation history and in Payments tab.
