Billable Expense on a Customer Profitability Report Disappears when Billed

When you record an expense via Vendor Bills, you have an option to tick the Billable box and associate it with a customer. This amount will appear under the Total Cost column of the Customer Profitability report (under Reports > Customers/Receivables)l. This expense can then be billed back to the customer by invoicing it. However, when you invoice this billable expense, you will notice that the amount will disappear from the report. 


The initial reaction from users is that the cost is will be understated because the it disappeared. But the real reason why the billable expense amount disappeared is because the cost was transferred to the invoice which billed it. Thus, profitability remains intact and correct.
