Sierra Design is an interior design firm. The firm uses a job cost system in which each client is a different "job." Sierra Design traces direct labor, licensing costs, and travel costs directly to each job (client). It allocates indirect costs to jobs based on a predetermined indirect cost allocation rate computed as a percentage of direct labor costs.
