Job costing The Gonzalez Company uses a job order costing system at its plant in Green Bay, Wisconsin. The plant has a machining department and a finishing department. The company uses two cost driver rates for allocating manufacturing overhead costs to job orders: one on the basis of machine hours for allocating machining department overhead costs and the other on the basis of direct labor cost for allocating the finishing department overhead costs.
