Why Auditing is Essential for Cleaning & Facility Management Businesses

Cleaning and facility management companies handle multi-location contracts, government tenders, subcontracting agreements, and labor-intensive operations, making financial audits critical. Here’s why audits are crucial:

1. Compliance with Financial & Tax Regulations

• Singapore Companies Act Compliance: Cleaning firms and facility management companies registered as private limited companies must submit audited financial statements to ACRA.
• GST & Tax Compliance:
  • Cleaning and facility management services are taxable under GST, while
  • Certain government-funded cleaning projects and waste disposal services may qualify for zero-rated GST.
  • Auditors verify GST classifications, tax deductions, and compliance with IRAS regulations.
• National Environment Agency (NEA) & Licensing Compliance:
  • Cleaning companies must comply with NEA’s environmental safety regulations, waste disposal licenses, and hygiene standards.
  • Facility management firms must meet Workplace Safety and Health (WSH) regulations for staff handling hazardous materials.

2. Revenue Recognition & Multi-Site Contract Audits

• Cleaning companies generate revenue from contract-based services, ad-hoc cleaning jobs, waste management contracts, and facility maintenance agreements.
• Auditors verify that revenue recognition policies comply with SFRS 15 (Revenue from Contracts with Customers).
• Deferred revenue from long-term service contracts and multi-location maintenance agreements must be accounted for properly.

3. Payroll Compliance & Foreign Worker Levy Audits

• Cleaning and facility management companies employ large numbers of foreign workers and subcontractors, requiring compliance with MOM employment laws.
• Auditors verify that CPF contributions, foreign worker levies, and salary payments comply with MOM regulations.

4. Equipment & Maintenance Cost Audits

• Cleaning firms invest in industrial cleaning equipment, maintenance tools, and fleet vehicles, requiring proper depreciation accounting.
• Auditors assess whether businesses apply the correct depreciation method (straight-line or reducing balance) for cleaning machinery and facility maintenance tools under SFRS 16 (Leases).

5. Fraud Prevention & Government Tender Compliance

• The cleaning and facility management industry is vulnerable to overbilling, ghost employees, fake work reports, and mismanaged subcontractor payments.
• Auditors conduct random payroll verification, contractor payment tracking, and financial risk assessments to detect fraudulent activities.

6. Investor & Government Contract Readiness

• Investors and government agencies require audited financial statements before approving funding for infrastructure maintenance, cleaning projects, and industrial facility contracts.
• Audits improve financial credibility and compliance with National Environment Agency (NEA) and government tendering regulations.

Key Audit Challenges Faced by Cleaning & Facility Management Companies

Despite its importance, auditing cleaning and facility management businesses presents challenges due to multi-location operations, contract-based revenue models, high payroll costs, and regulatory compliance complexities.

1. Multi-Site Contract Revenue Recognition & Deferred Income Accounting

• Cleaning businesses operate multiple client sites under long-term contracts, requiring accurate revenue recognition.
• Auditors must verify that contract-based revenue is properly recorded under SFRS 15 and deferred income is accounted for correctly.
• Delayed client payments or contract disputes can affect cash flow and financial stability.

2. GST Compliance for Service-Based & Government Cleaning Contracts

• Commercial cleaning services, facility maintenance, and waste management contracts are taxable under GST, while
• Some government cleaning contracts may be zero-rated for GST if part of a national hygiene program.
• Auditors verify that GST classifications are correctly applied to service invoices and contract-based revenue.

3. High Payroll Costs & Worker Levy Audits

• Cleaning companies employ high numbers of foreign workers and contract-based staff, requiring accurate payroll tracking.
• Auditors ensure compliance with CPF contributions, foreign worker levies, and wage regulations under MOM’s Employment Act.

4. Equipment Depreciation & Fleet Maintenance Audits

• Facility management firms invest in cleaning machines, HVAC maintenance tools, security equipment, and fleet vehicles, requiring proper asset depreciation tracking.
• Auditors assess whether businesses follow SFRS 16 (Leases) and IFRS 16 (Asset Management) for leased cleaning machinery and service vehicles.

5. Fraud Risks in Payroll & Cleaning Subcontractor Payments

• The industry faces risks related to ghost employees, duplicate contractor invoices, and non-existent work reports.
• Auditors conduct random site audits, contractor verification, and financial fraud detection analyses.

6. Forex & International Supplier Payment Compliance

• Many facility management firms procure industrial cleaning equipment from overseas suppliers, requiring forex compliance.
• Auditors assess whether forex gains/losses and multi-currency transactions are properly accounted for.
