Insourcing vs. Outsourcing: Evaluating Labour-Intensive Job Functions

Understanding Labour-Intensive Roles

For large-scale, customer-facing businesses and complexes, many critical roles are labour-intensive. These teams, including cleaning, waste management, landscaping, or maintenance, work together to deliver exceptional customer experiences. Whether front-of-house or back-of-house, highly technical specialists or dynamic generalists, there comes a time when businesses must weigh the benefits of keeping these teams in-house against the costs of outsourcing.

Careful consideration is essential to make informed decisions. For example, we recently assisted a client in retendering a labour-intensive waste management function, comparing tender responses to an in-house cost estimate. This benchmark ensured the client had access to the best available options.

Financial Considerations for Insourcing vs. Outsourcing

The primary financial metric for comparison is the weighted average labour rate. This rate is influenced by several factors:

1. Enterprise Bargaining Agreement (EBA)

The EBA is a legally binding agreement between employers and employees (often represented by a union) that sets minimum working conditions, including labour rates for regular hours, weekends, public holidays, and overtime.

2. Organisational Structure and Timesheet Estimates

Managerial roles are essential but costly. Key questions to ensure accurate analysis include:

  • Does the team always require a shift manager?
  • How does headcount vary during peak periods?
  • What contingency margin is needed for unexpected surges?

Incorporating detailed data from on-the-ground operations improves the accuracy of the weighted average labour rate.

3. Client Savings Pressures

While the EBA sets the minimum cost, the maximum is limited by current expenditure and potential savings. Balancing these factors creates an optimal scenario where workers receive fair wages while delivering cost savings to the client.

Additional Cost Factors

1. Staffing Onboarding Costs

Annual labour-related costs include:

  • Sick and annual leave allowances
  • Superannuation and payroll tax
  • Training and upskilling expenses

2. Fixed Assets

Labour-intensive roles often require equipment, which may put insourcing at a disadvantage compared to outsourced tenders that include equipment in their offers. Examples include:

  • Vehicles for transportation
  • Handheld equipment and uniforms
  • Relevant infrastructure

Depreciation and ownership costs of these assets must also be factored in.

3. Variable, Consumable Assets

These include:

  • Cleaning supplies
  • Fuel or bins
  • Maintenance and replacement costs

Note that Year 1 costs for insourcing are typically higher due to fixed asset acquisition and onboarding expenses, but costs often stabilize from Year 2 onward.

Qualitative Pros and Cons

Beyond financials, qualitative factors play a significant role. Below is a comparison of insourcing and outsourcing:

By carefully gathering and analyzing the above factors, businesses can estimate total yearly costs and compare them to the weighted average labour rate. This approach provides clarity in complex procurement decisions, whether the goal is to pursue a managerially preferred insourcing option or to use insourcing estimates to drive competitive pressure in outsourcing tenders.

Ultimately, a well-informed insourcing vs. outsourcing decision can deliver significant savings while maintaining quality.
