Bethel Bakery manufactures frosted sugar cookies. They maintain separate work-in-process accounts for their blending, cutting, baking, decorating…

Process costing is an accounting method used when a company produces large volumes of identical or very similar products in a continuous flow. Costs are accumulated for each stage of production or department over a period of time and then averaged over the total units produced. The use of separate Work-in-Process (WIP) accounts for each distinct department (blending, cutting, baking, etc.) is a hallmark of this system, as it allows for tracking the costs incurred at each step of the manufacturing process before they are transferred to the next department.

A. Job costing: This method is used for unique, custom-made products or services where costs can be traced to a specific "job," not for mass-producing homogeneous items like cookies.

C. Departmental costing: This is a general term, often referring to the allocation of overhead using departmental rates. Process costing is the specific costing system that uses departments to accumulate all product costs (materials, labor, and overhead).

D. Activity-based costing: This is a method for allocating overhead costs based on specific activities. It is not a complete costing system itself but a refinement that can be used alongside either job or process costing.

Section 4.1, "Compare and Contrast Job Order Costing and Process Costing," Paragraph 4: "Process costing is the optimal system for a company that produces a homogeneous product using a continuous process. Costs are tracked by each department..." This directly supports the use of process costing for a product like cookies made in a series of departments.

Section 4.4, "Journalize Transactions for a Process Costing System," Figure 4.13: This section illustrates the flow of costs, showing journal entries that debit separate Work in Process Inventory accounts for each department (e.g., WIP–Shaping Department, WIP–Packaging Department) as goods move through production. This confirms the practice described in the question.

Chapter 4, "How Is Process Costing Used to Track Production Costs?," Section 4.1, "A Comparison of Job Costing and Process Costing": "Process costing is used for production processes that result in a large volume of homogenous products... Costs are tracked by processing department." This reference, directly from a Saylor-approved text, validates that the bakery's departmental structure and product type align with process costing.
