When you select an invoice method different than 'No Invoice', all the
parts lines except the 'Remove' ones and the fee lines will be invoiced.
When you print a quotation, the price of parts and fees is shown
only if you have an invoice method (you only have the quantity if you
don't invoice)
The invoice is available through a stat button.
The price of removed parts is set to 0.0 by default as it won't be
invoiced.
Now that property is computed automatically.
In some case, the compute will take the first on available.
So, the order (sequence) allow to specify the priority.
