Costs of subcontracted work are basically the same as direct materials; direct staff costs are the same as direct labour, studio overhead is the same as manufacturing overhead, and completed projects are the same as finished goods. Apart from the difference in terms, the accounting methods used by the company are identical to the methods used by manufacturing companies. HAC uses a job-order costing system, applying studio overhead to work in process on the basis of direct staff costs.
