Is it possible to define a balance account of a vendor from which money will be deducted each time the vendor's service is sold? For example, I've a balance of $1000 in vendor A's account, selling service VA, its cost automatically deducted from vendor A's account.
On the other hand, vendor B doesn't hold any balance from us, but bills us for every service package sold. So, once service VB is sold, a vendor bill automatically added using the cost price of the service.
Can the default installation of Odoo 11 do either of those?
Also, which model holds the cost price defined for each product?
