Manufacturing companies manage complex operations involving raw materials, production processes, inventory, machinery, staff and customer orders. Their financial statements may include significant stock balances, work in progress, production costs, equipment, leases and estimates about obsolete or slow-moving goods. These areas require careful records and sound accounting judgements.
An independent audit provides an examination of a company’s financial statements and supporting records. It can give directors, shareholders, lenders, investors and other stakeholders greater confidence in the reported financial information.
Koh & Lim Audit PAC provides audit services for manufacturing companies in Singapore. We work with businesses involved in food production, electronics, precision engineering, chemicals, industrial components, packaging, consumer products and other manufacturing activities.
Independent audit services for manufacturers
An audit involves gathering evidence to assess whether a company’s financial statements are prepared, in all material respects, in accordance with the applicable financial reporting framework and relevant requirements.
For a manufacturer, an audit may involve more than checking sales invoices and bank transactions. The audit team needs to understand how the company purchases materials, manages production, calculates product costs, values inventory and records revenue. The nature of the audit work depends on the company’s size, operations, systems, locations and financial reporting risks.
Our audit approach is designed around the company’s circumstances. We discuss how the business operates, understand its accounting processes and plan procedures that address relevant areas of the financial statements. We also communicate information needs and audit matters to management throughout the engagement.
Why manufacturing companies may need an audit
A manufacturing company may need an audit to meet statutory requirements, satisfy a parent company, comply with financing terms or provide assurance requested by shareholders, investors or business partners. Even where an audit is not required by statute, a bank, investor or overseas group may request audited financial statements.
Some Singapore companies may qualify for an audit exemption, subject to the applicable criteria and circumstances. ACRA’s guidance explains the small company audit exemption framework. Companies should confirm their eligibility based on their specific situation rather than assume that being privately owned or small automatically removes the audit requirement. www.acra.gov.sg
Directors remain responsible for the company’s financial reporting. ACRA states that directors of companies that are not audit exempt must present audited financial statements. www.acra.gov.sg The applicable accounting standards also depend on the company and its circumstances. www.acra.gov.sg
An audit may also support discussions with lenders, investors and other stakeholders by providing an independent report on the financial statements. For manufacturing groups, the audit may be part of a wider reporting process involving a parent company, subsidiaries or overseas operations.
Understanding manufacturing accounting
Manufacturers commonly purchase raw materials and convert them into finished products through a series of production activities. The company may also hold partially completed goods, packaging, spare parts and goods awaiting delivery.
Financial reporting therefore requires processes that connect purchasing, production, inventory, sales and general ledger records. During the audit, we may consider how the company:
- Records purchases of raw materials and production supplies
- Tracks materials issued to production
- Allocates labour and manufacturing overhead
- Calculates work in progress and finished goods
- Assesses inventory at the reporting date
- Identifies damaged, obsolete or slow-moving stock
- Records sales, customer discounts and returns
- Accounts for rebates, warranties and other customer obligations
- Records machinery, production lines and other fixed assets
- Reconciles operational records with the accounting system
Reliable production and inventory records help management monitor margins and capacity. They also provide evidence to support the amounts reported in the financial statements.
Inventory and stocktake procedures
Inventory can be a significant asset for a manufacturing business. It may include raw materials, consumables, work in progress, finished goods and spare parts. The company needs processes to record stock movements and determine what inventory it owns at the reporting date.
The audit may include attending a physical stocktake, observing management’s count procedures, performing test counts and reviewing how inventory records are reconciled to the general ledger. The timing and nature of these procedures depend on the audit circumstances and the company’s inventory systems.
Where the stocktake is conducted on a date other than year-end, the company should maintain records that allow stock movements between the count date and reporting date to be reconciled. These may include goods received notes, production records, delivery documents, sales records and inventory adjustments.
For inventory held at third-party warehouses or customer sites, the company may need to maintain appropriate records and obtain evidence of quantities held. Management should also identify stock that is damaged, expired, discontinued or no longer expected to be sold in the ordinary course of business.
Valuation of raw materials, work in progress and finished goods
Manufacturing inventory may require different costing methods depending on the company’s systems and accounting policies. Raw materials may be valued using purchase costs, while work in progress and finished goods may include materials, direct labour and an allocation of production overheads.
The audit may examine how the company calculates product costs, whether the costing method is applied consistently and whether the records support the amounts included in inventory. We may compare the cost calculations with purchase invoices, payroll records, production reports and overhead schedules.
Work in progress can be more difficult to measure because products may be at different stages of completion. The company should have a method for assessing how much material, labour and production activity has been applied to items still in process. Clear production records and consistent stage-of-completion assumptions help support the valuation.
Inventory values may also need to reflect changes in selling prices, production costs or market demand. If goods are slow-moving or expected to sell below cost, management should assess whether an adjustment is required under the applicable accounting framework. The audit may review ageing reports, subsequent sales, inventory movements and management’s assessment of recoverability.
Production costs and overhead allocation
Manufacturing costs may include raw materials, direct labour, machine operating costs, factory rent, utilities, depreciation, maintenance and quality control. The audit may assess whether these costs are correctly classified, recorded in the proper period and allocated consistently between inventory and expenses.
A manufacturer should be able to explain how it allocates indirect production costs to products. These may include factory supervision, equipment depreciation, utilities and other shared production expenses. The basis of allocation should be applied consistently and supported by reliable production data.
Where production volume changes significantly, the company may need to review how it treats fixed manufacturing overhead. Underutilised capacity, factory downtime, production interruptions or exceptional wastage may affect how costs should be reflected in the financial statements. Management should keep records of unusual operating conditions and explain how they have been considered in its accounting.
The audit may also compare actual costs with budgets, standard costs or prior periods. Significant differences may arise from changes in material prices, energy costs, labour rates, production yields or supplier terms. Explaining these movements helps management and the audit team understand changes in gross margins.
Revenue, sales cut-off and customer returns
Manufacturers may sell products to local or overseas distributors, retailers, wholesalers or direct customers. The timing of revenue recognition can depend on the contract terms, delivery arrangements, customer acceptance requirements and the applicable financial reporting framework.
The audit may examine customer contracts, purchase orders, invoices, delivery records, shipping documents, acceptance certificates, credit notes and receipts after year-end. These records help assess whether revenue was recorded in the correct period and whether the recorded sale is supported.
Sales cut-off is particularly important around the financial year-end. The company should be able to identify goods that have been dispatched, delivered or accepted before and after year-end, based on the relevant contract terms. This helps ensure that sales and inventory movements are recorded in the appropriate period.
The audit may also review customer rebates, discounts, returns and warranty arrangements. Manufacturers should maintain records of sales incentives, credit notes issued after year-end, return requests and warranty claims. These items may affect the amount of revenue recorded or require a liability or other adjustment.
Suppliers, purchasing and foreign currency
Manufacturers often rely on multiple suppliers for raw materials, components, packaging and machinery. The audit may examine purchasing controls, supplier balances, goods received records and invoices to assess whether purchases and liabilities are complete and recorded in the right period.
Goods may be received before the supplier’s invoice arrives. The company should have a process to identify these items and record the related liability or accrual when required. Matching purchase orders, receiving documents and supplier invoices can help identify differences in quantity, pricing or delivery terms.
Where materials or equipment are purchased from overseas suppliers, transactions may be denominated in foreign currencies. The audit may review how foreign currency transactions and year-end balances are recorded and translated, as well as the related gains or losses.
Machinery, production lines and leased assets
Manufacturing businesses may invest in production equipment, factory machinery, tooling, testing systems, vehicles and warehouse equipment. The audit may examine additions, disposals, depreciation, impairment indicators and the completeness of the company’s fixed asset register.
The company should keep records that identify each significant asset, its cost, location, date placed into use and depreciation policy. Where equipment is under construction or installation, management should track the related costs and determine when the asset is ready for use.
Leased factory premises, machinery and equipment may require specific accounting treatment. The audit may review lease contracts, payment schedules, renewal options and management’s accounting calculations. The company should also consider whether its asset records reflect disposals, upgrades or equipment that is no longer in use.
If machinery becomes idle, damaged or technologically outdated, management may need to consider whether there are indicators that its carrying value should be reviewed. Keeping an up-to-date asset register and maintenance records can support this assessment.
Payroll, production staff and subcontracted work
A manufacturer’s costs may include wages, overtime, bonuses, employer contributions and other employee benefits. The audit may review payroll records, staff cost allocations and amounts owed to employees at year-end.
Where employees work across different production lines, departments or projects, the company may allocate labour costs using time records, production hours or another consistent basis. Clear timekeeping and payroll records help support the allocation.
Some manufacturers also use subcontractors for assembly, packaging, transport, maintenance or specialised processes. These costs should be supported by contracts, invoices, delivery records or service confirmations. Work received before year-end but invoiced later may need to be accrued.
Borrowings, cash flow and commitments
Manufacturing companies may need financing for machinery, inventory, factory premises and working capital. The audit may include reviewing bank balances, loan agreements, interest costs, security arrangements and any borrowing covenants.
The company may also have commitments to purchase materials, acquire machinery or complete factory upgrades. Management should identify significant commitments and assess whether they need to be disclosed in the financial statements.
Cash flow can be affected by changes in inventory levels, customer payment terms, supplier pricing and production schedules. If the company faces losses, declining demand, overdue receivables or difficulties renewing financing, directors may need to consider the effect on the company’s financial position and its ability to continue operating.
Audit preparation for manufacturing companies
Organising records before the audit begins can help the engagement progress more smoothly. Manufacturing companies may find it useful to prepare:
- The trial balance and draft financial statements
- Bank statements and reconciliations
- Inventory listings by category and location
- Stocktake instructions, count sheets and reconciliation records
- Work in progress and product costing schedules
- Raw material, labour and overhead calculations
- Sales records, delivery documents and customer contracts
- Supplier statements, invoices and goods received records
- Fixed asset and lease schedules
- Payroll records and staff cost allocations
- Loan agreements and covenant calculations
- Details of obsolete stock, claims, warranties and commitments
A staff member who can coordinate audit requests and explain production or inventory processes can help reduce delays. Management should also prepare explanations for unusual variances, year-end adjustments and material changes in stock levels or gross margins.
Our audit process
Our audit process starts with understanding the company’s manufacturing activities, financial reporting timetable and accounting systems. We discuss significant changes during the year, such as new products, production lines, facilities, suppliers or customer arrangements.
We then plan the audit work and agree on the information needed. Procedures may include testing transactions, reviewing estimates, observing inventory counts, examining contracts, confirming balances and assessing financial statement disclosures.
At the end of the audit, we discuss significant findings and proposed adjustments with management. The auditor’s report is issued based on the audit evidence obtained and the applicable professional requirements.
The timing of the audit depends on the readiness of the records, the number of locations, the complexity of inventory and production costing, and how quickly outstanding questions are resolved. Early preparation is especially useful when the company has multiple warehouses, overseas suppliers or a large year-end stocktake.
Choosing an auditor for a manufacturing company
When choosing an auditor, manufacturers may want to consider whether the audit team understands inventory, production costs and fixed assets. Clear communication, practical information requests and an agreed timetable can also help the finance and operations teams prepare.
An audit does not replace management’s own inventory controls, production monitoring or financial reporting responsibilities. The company remains responsible for accurate records and for preparing financial statements in accordance with the applicable requirements.
