My customer has an arrangement for substantial discounts with my supplier (they buy replacement parts directly from the supplier, which is how they achieved the discounts). I manufacture a product for my customer and I get to make use of the discount only if I'm buying it as part of my customer's project. So when quoting work I have 2 raw material costs, a discount cost for Customer A, and the normal cost for Customer B.

Is there a way to arrange this in Odoo, without making different products? How would I (or the system) select which costing to use?
