Create new item for invoice

How can I add a new button for the invoice?
Go to the Item Settings under Settings/Items.

Here, you can create a new item, such as breakfast, parking, spa services, or other additional services.

Reception Button: Enable this option if you want the item to be selectable directly in the booking with a single click. This allows staff to quickly add the item during check-in or when making changes.

Charge per Night: Select this option if the item should be charged for each booked night. This is useful, for example, for breakfast, parking, or other recurring services.

After saving, the new item will be available in the invoicing area and can be used directly for bookings or billing.
