First, it is necessary to separate two terms, Total and Total Due (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, sale an item or with the surcharge but not when you take payment.
Total Due or Balance Due - the remaining amount to be charged.
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 Payments tab:
On click on this button 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.
