Each asset can be given a base, unit, and daily cost. The net cost of a reservation is the base cost plus the unit times the number of units or the daily cost times the number of days. In the example here the location would cost $10 plus $1 per hour up to a maximum of 8 hours. Therefore:

A 4 hour reservation would be $14

A 4 hour, 30 minute reservation would be $15

A 10 hour reservation would be $18

In addition each organization and event type can be given a billing factor that represents a discount or surcharge on these rates.
