What is Job Order Costing? 

Job Costing, as the name implies, allows companies to track the revenues and costs of each job. Job costing systems record revenues and costs for unique units of product that can be easily distinguished from other units of the product. 

This allows managers to assess the accuracy of cost estimates (for pricing and budgeting purposes), determine profitability, and track costs throughout the project may identify unexpected changes early on.

What is Process Costing?

Process costing allows companies to track the costs associated with a specific process or Activity. Process costing systems record revenues and costs for batches of identical units of product.

Comparison of Job Costing with Process Costing

A process costing system is used by companies that produce similar or identical units of product in batches employing a consistent process. 

A job costing system is used by companies that produce unique products or jobs. 

Process costing systems track costs by processing department, whereas job costing systems track costs by job.

Accounts Used to Track Product Costing

The three inventory accounts that accountants use to track product cost information—raw materials inventory, work-in-process inventory, and finished goods inventory. 

These three inventory accounts are used to record product cost information for both process costing and job costing systems. 

However, several work-in-process inventory accounts are typically used in a process costing system to track the flow of product costs through each production department. Thus each department has its own work-in-process inventory account. 

(For the purposes of this material, assume each department represents a production process. This explains the term process costing because we are tracking costs by process.) 

The sum of all work-in-process inventory accounts represents total work in process for the company.

Recall the three components of product costs—direct materials, direct labor, and manufacturing overhead. 

Assigning these product costs to individual products remains an important goal for process costing, just as with job costing. However, instead of assigning product costs to individual jobs (shown on a job cost sheet), process costing assigns these costs to departments (shown on a departmental production cost report).
