   項目	必須	説明

   Add-on type	必須	The category — transport, food, service, and so on.
   Price	必須	Zero or more.
   Unit	必須	How it is counted: per stay, per night, per person, per item.
   Tax type	任意	Whether VAT applies.
   Tax included	任意	Whether the price already contains tax.

2. Selling an add-on#

Attach the add-on when taking or editing a booking. It appears as its own invoice line, so revenue from extras stays visible separately from room revenue.

Price an add-on at zero only when it is genuinely free. A zero line still records that it was provided; a missing line records nothing at all.
