Hi

I am doing work for a catering company. They quite like Odoo however there is a requirement that I cannot seem to satisfy in my testing. 

They order raw ingredients from suppliers and then make food with those ingredients. I can see that the Bill of Materials will suit this very nicely. However they also need to calculate the cost of the items used in the individual Bill of Materials so that they can see if that item is worth selling.

For example, they order from a supplier 1KG of ground beef @ $10 and 1KG of flour @ $10. Their BoM for a Burger will use 250gms of Ground Beef (effectively costing $2.5) and 250gms of Flour (effectively costing $2.5). So...

If the customer orders 1 x Burgers they want Odoo to calculate that the cost of that order was $5

If the customer orders 2 x Burgers they want Odoo to calculate that the cost of that order was $10  

Can Odoo do this? I see that there were some additional community modules for Version 7. Do these exist for Version 9?

Thanks!
