Sale Order Line Not Billable

This module lets you flag a product as not billable directly on the product form, next to the invoicing policy field. The new 'Billable' checkbox is enabled by default, so existing products keep behaving as before until you uncheck it.

When a sales order contains a non-billable product, the module changes how Odoo calculates what is left to invoice:

• The quantity to invoice for that line is forced to zero, so it never appears as something waiting to be billed.
• The invoiced quantity is set to the ordered quantity, so the line is treated as already fully handled and does not stay open.
• When you create the invoice from the sales order, non-billable lines are filtered out and are not copied into the invoice.

This applies to the sales order and its lines, and to the product form. There are no new menus or reports; the change is visible in the product screen and in the invoicing flow of sales orders. Products without a product set on the line are kept, so only lines linked to a non-billable product are removed.
