Adding Internal / Unbillable Items to Events
You may wish to add items to your events which are needed to execute the event but aren't going to be billed for and shouldn't appear on the proposal, contract, any addendums, or invoices. To mark an item as unbillable (an internal-use-only item), simply check the unbillable box when you add the item to the function or event-wide details:
When you check unbillable the price field will be hidden (since you are not billing for these items), but you are still able to enter a cost if needed. This ensures that the event's profit and loss is calculated accurately.
