Yes, I'm referring to the Vendor Bill.  I enter the Vendor Bill, mark it billable and note the customer.  BUT, when I go to Customer Invoice, I bill by % complete of an Estimate and not by selecting Add Items.  You need to use Add Items in order to get the Vendor bill applied to the Customer Invoice.

If I'm not using the Add Item of the Vendor Bill, how do I know I invoiced the Custom with the Vendor Bill?  How do I make the BILLABLE of the Vendor Bill noted as billed?
