5. The Nature of Process Cost Systems
Similarities and Differences Between Job Order Cost and Process Cost Systems
Job Order Cost
Costs assigned to each job.
Products have unique characteristics.
Process Cost
Costs tracked through a series of connected manufacturing processes or departments.
Products are uniform or relatively homogeneous and produced in a large volume.
SO 2 Explain the similarities and differences between job order cost and process cost systems.

Similarities and Differences Between Job Order Cost and Process Cost Systems
Illustration 21-3
SO 2 Explain the similarities and differences between job order and process cost systems.

7. The Nature of Process Cost Systems
Similarities
Both costing systems track three manufacturing cost elements—direct materials, direct labor, and manufacturing overhead.
Both costing systems debit
Raw materials to Raw Materials Inventory;
Factory labor to Factory Labor; and
Manufacturing overhead costs to Manufacturing Overhead.
SO 2 Explain the similarities and differences between job order and process cost systems.

8. The Nature of Process Cost Systems
Similarities
Both systems accumulate all manufacturing costs by debits to
Raw Materials Inventory,
Factory Labor, and
Manufacturing Overhead.
Both systems then assign these costs to the same accounts—Work in Process, Finished Goods Inventory, and Cost of Goods Sold.
SO 2 Explain the similarities and differences between job order and process cost systems.

9. The Nature of Process Cost Systems
Differences
Number of WIP accounts used.
Job order uses one Work in Process account.
Process uses multiple work in process accounts.
Documents used to track costs.
Job order charges costs to individual jobs and summarizes them in a job cost sheet.
Process summarizes costs in a production cost report for each department.
SO 2 Explain the similarities and differences between job order and process cost systems.

10. The Nature of Process Cost Systems
Differences
Point at which costs are totaled.
Job order totals costs when the job is completed.
Process totals costs at the end of a period of time.
Unit cost computations.
Job order, unit cost is the total cost per job divided by units produced.
Process, unit cost is total manufacturing costs for the period divided by units produced during the period.

Ruth Company manufactures ZEBO through two processes: blending and bottling. In June, raw materials used were Blending $18,000 and Bottling $4,000. Factory labor costs were Blending $12,000 and Bottling $5,000. Manufacturing overhead costs were Blending $6,000 and Bottling $2,500. The company transfers units completed at a cost of $19,000 in the Blending Department to the Bottling Department.

Costing Systems – Final Comments
Companies often use a combination of a process cost and a job order cost system.
Called operations costing, this hybrid system is similar to process costing in its assumption that standardized methods are used to manufacture the product.
At the same time, the product may have some customized, individual features that require the use of a job order cost system.
