28. What is the difference between job order costing and process costing?

Answer: C

Explanation:

Job order costing traces product costs to the product itself.

In job order costing, costs are specifically traced to individual jobs or products, allowing for precise cost allocation and tracking for each unique order.

A) Finished goods inventory consists of completed units at per-unit cost in job order costing.

This option is incorrect because while finished goods inventory does include completed units, the per-unit cost is not the primary distinction of job order costing. Job order costing is more focused on tracking costs for specific jobs rather than just the finished goods inventory.

B) Product costs are assigned to departments or processes in job order costing.

This statement is incorrect. Job order costing does not assign costs to departments or processes; that is a characteristic of process costing. Job order costing assigns costs directly to individual jobs.

C) Product costs are traced to the product in job order costing.

This option is correct as job order costing involves tracing product costs directly to specific jobs or orders, enabling detailed tracking of expenses associated with each unique product.

D) Finished goods inventory includes unsold completed products in process costing.

This option is incorrect. Process costing manages costs across processes but does not focus on individual job tracking. It does include finished goods, but the statement does not pertain to the distinction between job order and process costing.

Conclusion

The correct answer, C, clearly highlights that job order costing emphasizes the tracing of product costs to specific products, distinguishing it from other costing methods. All other options either mischaracterize job order costing or relate to process costing, which does not focus on individual job tracking.
