What is Job Order Costing? Definition, Example, And Objective

Job order costing

Job order costing is the method that allows the company to allocate manufacturing expenses to the specific job under consideration.

It’s best to be used when a business does not produce standard units. It’s mostly used in service-based/professional organizations where the scope of services performed for each client is different.

The mechanism of job order costing is based on the fact that each job is different and resources consumed in each of the jobs are different. So, the record for each job needs to be maintained separately.

However, the basic reporting format for the cost sheet remains the same: to report direct material, direct labor, and manufacturing overheads.

Cost order sheet

The cost order sheet is the main document that is used to extract the data for work in process account, finished goods account, and then cost of sales account. Hence, the accuracy of inputs in the job order costing directly impacts the financial statements.

If there are errors in the process to record to cost incurred in the job, it will impact the profitability of the job and the entire business. Depending on the materiality of error, it could even distort the decision of the financial statement users.


Businesses providing professional services

Professional service providers like chartered accountants, lawyers, private investment companies, and advisors can use job-order costing to keep a record of the work done/time spent on the job.

This helps to invoice the client based on the hours spent on the job and the extent of the resource usage.

These professional firms get details of employees’ hours worked on specific jobs by timesheets. This helps the firm to understand how many hours were consumed on the job, and the firms already keep data about the cost of the resource.

Hence, they reach the actual cost consumed in the performance of the job for a specific client in the specific job.

For instance, the firm of chartered accountants audits different clients from small and medium companies to giant listed companies with operations in different jurisdictions. Hence, they charge differently based on the extent of work performed and the risk of engagement.

Businesses in manufacturing industries

The job order costing is only suitable for the companies that produce customized products for their customers. The job order costing helps the business to track usage of the direct material, direct labor, and overheads.

If there is any variance in the job, the business can immediately identify as the span of the job is small compared to production for the whole business.

If the variance identified is un-controllable or due to macroeconomic factors, the business can negotiate the price with the customers based on inflation/changes in the variables.

Although, variance can be identified with process costing. However, it’s easy to allocate the variance for the specific job rather than allocating the variances to several processes/whole business.

Businesses performing medical services

Job order costing can be the best methodology of cost measurement for the medical services business. As the nature of the diseases is different for each patient and hospitals maintain a separate file for each patient admitted.

The patient file contains all the services performed for him/her, including physician check-ups, diagnosis tests, medicines consumed, and all other aspects of the services consumed.

This patient file is a cost order sheet in the eyes of the hospital’s accounting department. They invoice patients based on the patient file, which is different for each patient.

Hence, job order costing works best in the case of hospitals/medical services providers.
