Please pay attention to the Order Notes
When editing reservation details, you will see some reminders under certain settings, such as the maximum number of guests in the room, the number of rooms remaining for the selected dates, etc. If you accidentally ignore these reminders when adding this information and fill in the information incorrectly, then when you click the “Save” button, a highlighted error message will be displayed in the “Order Notes” box on the right, prompting you that for some reason, the changes you just made were not successfully saved.
Order Statuses and Room Availability
Every order has its current state marked by a status. When creating or editing an order, you will need to set a status for the order. For example, if it needs to be paid, select “Pending payment.”
According to the settings of the WooCommerce plugin, each order status has its own meaning and usage scenario. Please read this official WooCommerce document for details: Order Status in WooCommerce.
Status “Pending Payment”: It should be noted that when the order status is “Pending payment”, the available quantity of the room (stock) will not be reduced after the order is created or updated. When the order status changes to other, such as “Processing”, the available quantity of the room will be reduced accordingly.
Edit-ability of Orders
In some order statuses, you may find that the order content can no longer be edited. For example, when order status is “Processing“, you will see a message: “This order is no longer editable.“
A notification will appear suggesting to change the status to “Pending payment” to edit the order. Once you follow the suggestion and click the “Update” button to apply the changes, the item section will become editable.
Manually send order details emails
When guests book rooms themselves at the frontend, WooCommerce automatically sends corresponding emails to guests and website administrators. Unlike this, when you manually create or edit an order in the backend, these emails will not be sent automatically and you need to send them manually.
After creating or editing an order, you can send the order details (or any changes to the order) to the customer by selecting a corresponding action from the Order Actions drop-down menu on the right.
