and are two key approaches to tracking production costs. is used for unique, customized products, accumulating costs for each job separately. is used for standardized products made in continuous processes, accumulating costs by department or process.

These costing methods differ in how they track and assign costs. Job order costing uses and traces costs directly to specific jobs. Process costing averages costs over total units produced in each process. Understanding these approaches helps managers choose the right method for their production environment.
