When viewing your Events you can see the total revenue and total costs for it. The revenue and cost figures are the sums of any Sales Invoices and Purchase Orders linked to that Event.
Default Costs are useful when you wish to forecast profitability yet have not created Purchase Orders for your suppliers. The value of the Default Cost will be removed once a Purchase Order is linked to the Event.
You can create Default Costs based on the Private or Public Events and the number of days that the Events will run on. When you create an Event, Administrate will check to see if there is a default cost setup that matches the duration of it and if there is, the Default Cost(s) will be added to the Event financial details.
