Partial Invoices (Multiple Invoices per Rental)

When an invoice is created, there is a billing period in the upper left that shows the beginning and end date covered in the invoice (the period by default is the full duration of the job).

 

The date range can be set to be equal to the days that the user wants to bill for in the first invoice (subsequent invoices will default to the day after the end date you choose).  All resource bars within that date range will have their values show as line items when the invoice is regenerated.  Also all items (flat fees) with dates in that range will show as line items.  This is why having dates on items is important.  If there are no dates on an item it will recur on every invoice.
