When creating a package, relevant cost items must be added under the 'composition' heading.
For more information about other package settings, read Creating and editing packages
Add all extra cost items that are relevant if this package is booked.
Mandatory cost items are already applied to the reservation, but you can add them to a package to change the price of these cost items for reservations that include this package.
For packages of the type 'Fixed period' or 'Fixed total price', it is important to read the information about mandatory cost items: Mandatory costs in packages using a total price
Some cost items cannot be included in a package
A package cannot include cost items that are a percentage of the total rental amount, because the total rental amount itself contains factors that are based on a percentage. Calculating a percentage of a percentage is not possible, and therefore these types of cost items are not available for a package.
To solve this, change the relevant cost item to a percentage of the standard rent.
