The Real Cost of In-House Fulfilment vs. Outsourcing to a 3PL in Australia

Many Australian retailers start by handling fulfilment themselves to save money, until the warehouse rent, wages, and packaging costs add up. Others switch to a Third-Party Logistics (3PL) after spending more time fixing delivery errors than growing sales.

As storage costs climb and deliveries fall behind, the question becomes clear: which model actually works out better for your business, in-house fulfilment or outsourcing to a 3PL?

This article breaks down the real costs, hidden expenses, and when it makes financial sense to outsource fulfilment in Australia.

In-House vs 3PL: A Quick Comparison

Below is a quick breakdown of how in-house and 3PL fulfilment models compare for Australian retailers:

In-House Fulfilment

You store, pick, pack, and ship orders from your own warehouse or workspace,  managing staff, rent, and carriers yourself.

Best for: Small online retailers with steady, predictable order volumes.

Pros: Full control over packaging and stock access. Simple setup for low-order numbers.

Cons: Costs rise fast as volume grows: space, staffing, and time become major limits.

3PL (Third-Party Logistics)

A 3PL stores, packs, and ships your products from their warehouse, handling staff, systems, and transport for you.

Best for: Scaling businesses that want faster, more reliable delivery without new leases or staff hires.

Pros: Predictable costs, professional fulfilment teams, national reach, and integrated tracking.

Cons: You can’t physically check every order. Setup requires coordination and system alignment.

In-house fulfilment suits smaller retailers with steady order volumes, while 3PLs are ideal for growing Australian businesses that need scalability, time savings, and expert logistics support.

If you’re exploring 3PL options, Couriers & Freight connects Australian retailers with trusted local providers and helps you compare costs and choose a fulfilment setup that fits your business.

What In-House Fulfilment Really Costs

Running your own warehouse in Australia comes with more expenses than many business owners expect.

1. Rent and Utilities

In Sydney and Melbourne, warehouse rent now averages between $180 and $200 per square metre. A modest 400 m² space can cost about $7,000 a month before electricity, waste management, and insurance are even added.

2. Labour and Staffing

Warehouse assistants and pickers earn around $28–$33 an hour. Two full-time staff can cost roughly $10,000 a month, and that figure rises quickly during peak sales periods or holidays.

3. Equipment, Supplies, and Systems

Pallet jacks, shelving, barcode scanners, and packaging materials often exceed $20,000 a year. Warehouse management software adds another $200–$600 monthly, depending on order volume.

4. Hidden Costs

These often make the biggest dent in profit. Errors, staff turnover, and time spent managing returns can eat into margins fast. One incorrect order can erase profit once you factor in postage, replacements, and customer service time.

One Brisbane retailer discovered their in-house costs were 25% higher than expected after factoring in admin time and problem-solving. As your business grows, these ongoing costs can outweigh the benefits of managing fulfilment internally, especially compared to working with a 3PL.

The True Cost of Outsourcing to a 3PL

Outsourcing product fulfilment turns fixed warehouse expenses into flexible, pay-per-use costs which is one of the biggest advantages of working with a 3PL in Australia. This is a major advantage for growing Australian retailers.

Typical 3PL pricing in Australia includes:

• Receiving: $15–$30 per pallet
• Storage: $20–$30 per pallet per week (or by cubic metre for small items)
• Pick and Pack: $1.50–$3.00 per order
• Freight: Negotiated through the provider’s carrier network

Most 3PLs include labour, warehouse software, returns handling, and reporting in these fees, so you pay only for what you use. This makes it easier to track costs and scale up or down with seasonal demand.

For example, a 3PL company in Melbourne specialising in fashion fulfilment charges about $2.20 per pick and $25 per pallet per week. A brand sending 1,000 orders a month would spend roughly $7,000, less than half the cost of operating a small in-house warehouse.

A 3PL model also offers built-in flexibility. When order volumes rise, additional staff and space are added automatically. When sales slow, your storage and handling costs reduce. This flexibility makes 3PL fulfilment ideal for businesses expanding nationwide or trialling new product lines in Australia.

Couriers & Freight partners with trusted 3PL providers, including Gold Tiger, TLS, and Mr Express, to help Australian retailers find scalable, cost-effective fulfilment solutions that grow with their business.

4 Factors to Consider When Choosing Between In-House and 3PL

Beyond costs, a few practical factors can help you decide which fulfilment model fits your business best.

1. Order Volume and Seasonality

In-house fulfilment is practical for small Australian retailers sending fewer than 300 orders per month. But as sales grow, managing staff schedules, carrier pickups, and returns becomes difficult. 3PLs can quickly add warehouse staff and extend operating hours during busy seasons. For example, during Christmas or major online sales, a 3PL can process double the usual volume without the need for new hires.

2. Control and Visibility

Many owners worry that switching to a 3PL means losing control over stock. However, one Reddit user said they had been tracking everything manually through spreadsheets and emails from fulfilment partners, but it had become unsustainable. Modern 3PL systems give you online dashboards that show real-time inventory, order progress, and delivery updates. This lets you monitor operations and keep customers informed without being on the warehouse floor.

3. Scalability and Flexibility

Growing your in-house operation requires new leases, extra equipment, and more supervisors. These changes can take months and cost thousands of dollars before you see any return. A 3PL can add new products or cover new locations almost immediately. Their infrastructure is ready, so your cost per order stays steady even as volume increases. This is why many Australian brands switch to a 3PL once they reach 500 monthly orders.

4. Customer Experience

Fast, accurate deliveries build repeat business. Errors or delays cost more than just money; they affect trust. Professional 3PLs maintain strict accuracy targets and partner with multiple carriers to minimise issues. This results in faster deliveries, fewer mistakes, and happier customers.

When weighing in-house vs 3PL options, remember: reliable, accurate fulfilment often matters more than price alone. Reliable service keeps customers coming back. This is where partners such as Couriers & Freight help Australian retailers maintain performance and consistency across every delivery.

Comparing the Numbers: Sample Cost Breakdown

Below is an example monthly cost comparison for a small Australian retailer shipping around 1,000 orders per month.

‍

According to Knight Frank’s Q4 2024 industrial rent data and Fair Work wage rates, running a 400 m² warehouse in Australia can exceed $18,000 per month. By comparison, 3PL fulfilment for around 1,000 orders a month costs roughly between $7,000 and $8,500, including storage and handling.

When to Move from In-House to 3PL

At some point, your warehouse and processes can no longer keep up with orders. Here is how to know you have reached that point.

It’s time to consider outsourcing when fulfilment management starts taking more time than running your business itself. Common signs include:

• Staff regularly work overtime or weekends to meet shipping deadlines.
• Frequent customer complaints about missing items or late deliveries.
• Running out of storage space for new stock.
• Spending hours each week negotiating with couriers or tracking parcels manually.

Several business owners have shared similar experiences online. One commented, “I spent more time chasing couriers than working on my website.” Another said fulfilment eventually became a full-time job on its own.

When fulfilment starts stealing focus from sales and customer growth, it’s time to transition to a 3PL. The right provider can absorb these growing pains, giving you back the time to scale efficiently.
