External Audit for Manufacturing Companies in Laguna and Cavite

Manufacturing in Laguna and Cavite

Laguna and Cavite are among the Philippines' largest manufacturing provinces, hosting industrial estates, export processing zones, and a wide range of companies in automotive parts, electronics, food processing, chemicals, and other sectors. Many of these companies are registered with PEZA and operate within special economic zones.

Manufacturing companies in these provinces have accounting and audit requirements that differ from service or trading companies, particularly in the areas of inventory valuation, cost of goods sold, fixed asset-intensive operations, and PEZA compliance.

Inventory Audit Considerations

Inventory is typically one of the most significant balance sheet items for manufacturing companies and receives close attention in the external audit. Auditors verify inventory balances through physical observation of the inventory count, testing of the valuation method, and review of raw materials, work-in-process, and finished goods classifications.

Preparing for the inventory audit includes conducting a systematic physical count at or near year-end, maintaining accurate inventory records throughout the year, and ensuring that valuation methods — whether FIFO, weighted average, or specific identification — are consistently applied and documented.

Cost Accounting and Cost of Goods Sold

External auditors review the cost of goods sold and gross margin as part of the income statement audit. For manufacturing companies, this requires organized cost accounting records including direct materials, direct labor, and overhead allocation. Auditors will test the reasonableness of cost allocations and verify that costs are properly classified between manufacturing cost, selling expense, and administrative expense.

Maintaining organized cost accounting records throughout the year — rather than reconstructing them at year-end — significantly reduces audit time.

PEZA-Registered Companies: Additional Considerations

PEZA-registered companies are required to maintain separate books for PEZA-registered activities and non-PEZA activities where applicable, and to ensure that financial statements reflect compliance with PEZA reporting requirements. Auditors familiar with PEZA-registered entities understand the need to segregate PEZA-incentivized income from income subject to regular corporate income tax.

PEZA compliance documentation — including activity-specific financial records, cost center accounting, and PEZA annual reports — should be organized and available for the auditor to review.

Fixed Assets and Capital Expenditures

Manufacturing companies often have significant investments in property, plant, and equipment. Auditors verify that fixed assets exist, are properly valued, and that depreciation is calculated correctly. Capital expenditures made during the year must be distinguished from repairs and maintenance expenses.

A complete and up-to-date fixed asset register — with asset descriptions, acquisition dates, costs, accumulated depreciation, and disposals — is essential preparation for the audit.

BIR and SEC Compliance

Manufacturing companies must comply with SEC filing requirements for audited financial statements and with BIR requirements for annual income tax returns with attached audited statements. Companies with revenues above the VAT threshold must also file VAT returns and maintain VAT records aligned with the audited statements.
