Learning Objective 15-C2: Explain job cost sheets and how they are used in job order costing. Skip to question In a job order costing system, the costs of producing each job are accumulated on a separate job cost sheet. Costs of direct materials, direct labor, and overhead applied are accumulated separately on the job cost sheet and then added to determine the total cost of a job. Job cost sheets for jobs in process, finished jobs, and jobs sold make up subsidiary records controlled by general ledger accounts.
