Guide to Manufacturing Account Formats in Malaysia

A manufacturing account calculates the total cost of producing goods during a financial period. It records raw materials, labour, factory overheads, and work-in-progress adjustments before transferring the final cost of production to the trading account.

Running a factory in Malaysian industrial zones like Shah Alam, Nilai, or Penang’s Bayan Lepas rarely involves simple costs. 

Raw materials fluctuate in price, electricity bills swing with production output, and labour costs include EPF, SOCSO, and EIS contributions. Without a proper manufacturing account format, production margins can easily be miscalculated.

Hence our accounting firm will explain:

• How manufacturing accounts work in Malaysia
• Correct format used by accountants
• Components needed to produce accurate production cost calculations.

Manufacturing vs Trading Accounts: What Is the Difference?

Manufacturing accounts and trading accounts serve different roles in financial reporting.

A manufacturing account calculates production cost, while a trading account calculates profit from selling finished goods.

Manufacturing accounts are mainly used by manufacturers, factory accountants, and cost controllers, while trading accounts are used for overall financial performance evaluation.

Example of a Manufacturing Account Format (Vertical Layout)

The vertical format is the most common structure used in Malaysian accounting systems and ERP software.

This final Cost of Production figure is transferred to the Trading Account, where it forms part of the Cost of Goods Sold.

Who Needs a Manufacturing Account?

A manufacturing account is required for businesses that produce goods from raw materials or components before selling them. It helps track production costs accurately before calculating profit.

Businesses that typically require manufacturing accounts include:

Manufacturing companies

Factories that convert raw materials into finished goods, such as:

• Furniture manufacturers
• Electronics manufacturers
• Plastic injection moulding factories
• Metal fabrication companies
• Food processing plants

These businesses need manufacturing accounts to determine true production costs and product pricing.

Businesses that do NOT require manufacturing accounts

Retailers and trading businesses usually do not prepare manufacturing accounts because they purchase finished goods rather than produce them.

Examples include:

• Retail stores
• Wholesale distributors
• Online resellers
• Importers of finished products

These businesses typically prepare only trading accounts and profit and loss statements.

How Do Manufacturing Account Formats Work in Malaysia?

The modern manufacturing account format follows a multi-stage calculation process to capture every layer of production cost.

The typical calculation flow is:

Raw Materials → Prime Cost → Factory Cost → WIP Adjustment → Cost of Production

Under MPERS Section 13, Malaysian manufacturers must allocate fixed production overheads based on normal production capacity rather than peak output.

Example scenario:

A furniture manufacturer in Muar must classify production costs correctly:

• Wood and hardware components are Direct Materials
• Carpenter wages are Direct Labour
• Factory electricity and maintenance are Factory Overheads

Accurate classification ensures that financial statements remain compliant with Malaysian accounting standards.

What Are the Main Components of a Malaysian Manufacturing Account?

Manufacturing accounts divide costs into three primary categories.

Direct Materials

Direct materials refer to raw materials physically used in production.

Formula:

Opening Stock

• Purchases
• Carriage Inwards
  − Closing Stock

= Raw Materials Consumed

Examples include:

• Plastic pellets for injection moulding
• Fabric for garment manufacturing
• Steel components in metal fabrication

Direct Labour

Direct labour includes wages for employees directly involved in production.

This usually includes:

• Production line workers
• Machine operators
• Assembly staff

In Malaysia, direct labour costs often include statutory contributions such as:

• EPF (KWSP)
• SOCSO (PERKESO)
• EIS contributions

These costs are included because they are directly tied to production workers.

Factory Overheads

Factory overheads include indirect production costs necessary to operate the factory.

Examples include:

• Factory rent
• Machine depreciation
• Factory utilities
• Supervisor salaries
• Equipment maintenance

These costs cannot be traced to individual units but are essential for the manufacturing process.

What Is Prime Cost in Manufacturing Accounts?

Prime Cost represents the total direct production cost required to manufacture goods.

It consists of three elements:

1. Direct materials
2. Direct labour
3. Direct expenses

Formula:

Prime Cost = Direct Materials + Direct Labour + Direct Expenses

Example:

A garment factory may calculate prime cost as:

Factory overheads are added only after prime cost has been calculated.

Why Is WIP Adjustment Critical for Production Costs?

Work-in-Progress (WIP) refers to goods that have started production but are not yet finished.

WIP adjustments prevent production costs from being assigned to the wrong accounting period.

The formula works as follows:

Factory Cost

• Opening WIP
  − Closing WIP

= Cost of Production

Without this adjustment, financial statements may overstate or understate production efficiency.

Under MFRS 102, WIP must be valued at the lower of cost or net realisable value.

Expenses That Should NOT Be Included in a Manufacturing Account

Not all company expenses belong in the manufacturing account.

Costs that must not be included are:

• Marketing and advertising expenses
• Office administrative salaries
• Sales commissions
• Delivery expenses to customers
• Office utilities and rent

These belong in the Profit and Loss Statement, not production cost calculations.

How Are Raw Materials and WIP Valued in Malaysia?

Inventory valuation is governed by MFRS 102 and MPERS Section 13.

Inventory must be recorded at the lower of cost or net realisable value (NRV).

Common costing methods include:

FIFO is the most widely used method among Malaysian SMEs due to its simplicity and compatibility with accounting software.

How Manufacturing Accounts Link to Financial Statements

Manufacturing accounts form part of a larger financial reporting structure.

The cost flow follows this sequence:

The Cost of Production figure is transferred to the Trading Account, where it becomes part of the Cost of Goods Sold (COGS) calculation.

This makes sure that production costs are properly matched with sales revenue.

How Does LHDN E-Invoicing Affect Manufacturing Accounts?

Malaysia’s E-Invoicing rollout between 2024 and 2026 is changing how manufacturing costs must be documented.

Every purchase of raw materials must now be supported by a validated electronic invoice.

This means:

• Raw material purchases require verified supplier invoices
• Digital audit trails must exist for tax deductions
• Procurement systems must integrate with accounting software

Manufacturers without proper documentation may risk disallowed tax deductions during LHDN audits.

Step-by-Step Of How to Prepare a Manufacturing Account

Preparing a manufacturing account follows a clear sequence.

Step 1: Calculate Raw Materials Consumed

Opening Raw Materials

• Purchases
• Carriage Inwards
  − Closing Raw Materials

Step 2: Calculate Prime Cost

Raw Materials Consumed

• Direct Labour
• Direct Expenses

Step 3: Add Factory Overheads

Include all indirect production costs.

Examples include:

• Factory rent
• Depreciation of machinery
• Factory utilities
• Maintenance costs

Step 4: Adjust for Work in Progress

Factory Cost

• Opening WIP
  − Closing WIP

Step 5: Transfer Cost of Production

The final amount is transferred to the Trading Account.

Common Mistakes When Preparing Manufacturing Accounts

Many SMEs make avoidable errors when structuring their manufacturing accounts.

Common mistakes include:

Mixing factory and administrative costs

Office rent, marketing expenses, and administrative salaries do not belong in manufacturing accounts.

Ignoring Work-in-Progress adjustments

Failure to record WIP may distort production costs and profitability.

Incorrect overhead allocation

Factory overheads should be allocated based on normal production capacity, not maximum output.

Missing documentation for E-Invoicing

Manufacturing expenses without valid digital invoices may not be tax deductible.

Conclusion: True Cost of Production

Manufacturing accounts allow Malaysian manufacturers to clearly understand the true cost of producing goods before calculating profit.
