How can you use a backflush costing system to optimize inventory valuation?

1 What is backflush costing?

Backflush costing is a method of inventory valuation that delays the recording of costs until the finished goods are sold. Instead of allocating costs to work-in-process inventory at each stage of production, backflush costing assigns costs to finished goods based on standard or predetermined rates. This means that you do not need to track the inventory movements or the overhead costs for each production activity. You only need to record the costs of raw materials when they are purchased and the costs of finished goods when they are sold.

3 What are the challenges of backflush costing?

Backflush costing is not without its drawbacks, however. You may lose some information and control over the production process, which can affect your planning, budgeting, and decision-making. Additionally, you may not comply with the matching principle or generally accepted accounting principles (GAAP) or international financial reporting standards (IFRS). Furthermore, you may face resistance and skepticism from internal and external stakeholders, requiring you to provide supplementary information or reconciliations to support your inventory valuation and costing system. All of these challenges can make backflush costing difficult to use.

4 How can you implement backflush costing?

If you decide to use backflush costing for your inventory valuation, you need to take several steps to ensure its successful implementation. Firstly, evaluate your production process and environment. This includes ensuring that your production process is lean, stable, and standardized, and that your inventory levels are low and consistent. Additionally, assess the suitability and feasibility of backflush costing for your industry, product, and market. Secondly, establish your cost drivers and rates by identifying the cost drivers that affect your production costs and determining the standard or predetermined rates for each cost driver. Thirdly, design your accounting system and procedures to record the costs of raw materials when they are purchased and the costs of finished goods when they are sold. Lastly, monitor and adjust your backflush costing system by evaluating its performance and accuracy, comparing it with actual costs and outputs, adjusting cost drivers and rates periodically, and accounting for any variances or discrepancies that may arise.

5 What are some examples of backflush costing?

Backflush costing is a system commonly used by companies that operate in a lean or just-in-time production environment, with minimal inventory and short production cycles. This system is employed by the automotive, electronics, and pharmaceutical industries. For example, Toyota and Honda use backflush costing to account for their inventory costs, as they produce cars based on customer orders and specifications. Similarly, Apple and Samsung rely on backflush costing to account for their inventory costs, as they produce high-tech devices that have short life cycles, high demand, and low inventory turnover. The pharmaceutical industry also utilizes this system; companies such as Pfizer and Merck use backflush costing to account for their inventory costs due to strict quality standards, high research and development costs, and low inventory levels.
