Costs of subcontracted work	50,000	To completed projects	350,000
Direct staff costs	125,000
Studio overhead	250,000

Scott’s Outdoor Design is a service firm, so the names of the accounts it uses are different from the names used in manufacturing companies. Costs of Subcontracted Work is comparable to Direct Materials, Direct Staff Costs is equivalent to Direct Labour, Studio Overhead is equivalent to Manufacturing Overhead, and Completed Projects is equivalent to Finished Goods. Apart from the difference in terms, the accounting methods used by the company are identical to the methods used by manufacturing companies.

The company uses a job-order costing system and applies studio overhead to Work in Process on the basis of direct staff costs. At the end of January, only one job was still in process. This job (the XYZ Corporation headquarters project) had been charged with $20,800 in direct staff costs.
