The Finance Sub-Tabs
In the Invoice tab, you can decide if a task should be considered for invoicing when it is finished. If you decide to invoice the task, you can select to use the default payment and invoicing information defined in the client's Payment Terms tab or enter new information specifically for this task. What is more, this tab also records the important payment and invoicing information of this specific task: the task's invoice dates, payment status and payment date can be viewed here.
In the Currency tab, you can review the exchange rate between the base system currency and the currency used in the client's price profile for this task. If you have changed the exchange rate in Configuration, you can mark the date here, as well.
