If we send a quotation or confirm a sales order, confirmation is send to the contact (mostly a purchaser) of the company, who send us the order or requests a quotation. The confirmation should be adressed to this contact. The quotation or sales order should be linked to the company. How to establish this?
More info: If we use the contact as "customer", the sales order / quotation is linked to this contact, not to the company anymore. I cannot use invoice or delivery address, because they can be different too.
