Management Accounting Report: Job Order Costing, ABC, and Overheads

This report examines management accounting principles, specifically focusing on job order costing and activity-based costing (ABC) within the context of Turramurra Furniture. It explores the suitability of job order costing for customized furniture production, detailing the Work-in-Process (WIP) balance and calculating the cost of chairs in finished goods inventory. The report includes the computation of over or under applied overhead, different treatments for adjusting these over-applied overheads, and proposes an approach for adjusting over-applied material costs. Additionally, the report discusses the application of ABC for improved cost data reliability, especially considering potential product range expansion and overhead allocation concerns. The conclusion emphasizes the effectiveness of job order costing for specialized products, the adjustment of over-applied overhead, and the benefits of implementing ABC for accurate overhead allocation. References from academic journals and books are also included.

Introduction:
Turramurra furniture manufactures furniture, specialised for using with computers.
There are different furniture, produced under different job numbers. This report is prepared to
determine the cost of each type of furniture and explain the process of cost estimation under
job order costing system.
Body:
Suitable Circumstances for Job Order Costing System:
There are various circumstances in which the process of job order costing system can
be used by the organizations and individuals. The job order costing system is usually
employed by the firms that produce a number of products that are different in nature. It is an
extensively exploited costing system in the production along with the industries associated
with the service sector. The production firms that are using the job costing process generally
gain he orders for customised services and products (Öker and Adıgüzel 2016). These orders
that are customised in nature are known as batches or jobs. When a firm grants jobs and
orders for various products, the cost assignment to the product becomes a complex task. In
this scenario, the record of the cost for every specific job is kept due to the fact that each of
the jobs has various products and the various costs related with it (Trépanier et al. 2014). The
cost per unit of a specific job is calculated by dividing the overall cost allocated to that job by
the number of specific units associated with the job. The three basic elements of job costing
system include the materials, labour cost and the factory overhead.

Approach for Adjusting Over Applied Material Cost:
In order to mitigate the issues that is associated to the over or under application of the
overhead material, Turramurra Furniture Company looks to debit the manufacturing overhead
and credit the cost of goods sold and the second treatment of the manufacturing overhead is
debiting the manufacturing overhead cost with the work in process and debit the work in
process with the cost of goods sold. This would be able to mitigate the issues that is present
with the over and under application of the manufacturing overhead.

7MANAGEMENT ACCOUNTING
Activity Based Costing
The organization is concerned with their calculations and the application of the
overhead and is of the idea of using Activity Based Costing as it is looking for an expansion
of their product range and is even concerned about the overhead applications. Activity Based
Costing is generally utilised by the manufacturing companies as it improves the reliability of
the cost data and thereby manufacturing close to the true and authentic cost and better
categorising the costs that has been incurred by the firm during the time of the manufacturing
process (Tsai et al. 2014). The costing process is exploited in the product costing, target
costing, customer profitability, service pricing and profitability assessment. It has been
hugely popular as the companies can create an improved corporate strategy and concentration
if the costs are grasped effectively. The process of Activity Based Costing makes use of the
numerous costing pools managed by the activity in order to allocate the overhead costs
(Dong, Liu and Lin 2014). The idea has been that the activities are needed to manufacture the
products like the establishment of the machinery, purchasing the materials, examining the
finished products and assembling the the products. These activities can be expensive and
therefore the expense of the activities needs to be allocated to the product reliant on the usage
of the activities of the products.
An activity is a method that looks to consume the overhead resources. The aim is to
understand all the operations that is essential to manufacture the products of the organization
(Coşar, Guner and Tybout, 2016). This step requires the overhead costs related with every
activity that is to be assigned to the operations. Hence, Activity Based Costing is essential for
considering the product range and the overhead applications.

8MANAGEMENT ACCOUNTING
Conclusion:
It can be stated from the above discussion and calculations that job order costing is
very effective for determining the cost of different specialized products. The management has
allocated the overhead to the product cost at higher rate than the actual overhead rate.
However, the management can adjust the over applied overhead in different methods and
under both the methods, the cost of goods sold would get reduced.
The company can minimize the discrepancy related to the overhead allocation by
introducing activity based costing method. It would help the company to allocate the
overheads as per the benefits consumed by each product and also to determine the cost more
appropriately.
