When to Move Your eCommerce Operations from Direct Fulfilment to a Multi Hub 3PL

Growth does not usually break a warehouse all at once. It breaks it in November. Here is how to tell the moment is coming, and what to do about it before peak season decides for you.

Australians spent $82.6 billion online in 2025, up 14 per cent year on year, and online purchases now make up roughly 24 per cent of all retail spending, according to the Australia Post eCommerce Report 2026. Growth at that pace is good news for merchants right up until the warehouse stops coping.

Most Australian eCommerce businesses never really decide to outsource fulfilment. They run out of racking, run out of casual staff in November, and make the call under pressure mid peak. That is an expensive way to choose a logistics model.

Here is what you need to know about the thresholds that signal a move, how a multi hub model works across Australian geography, what it costs, and how to migrate stock without disrupting trading.

What is a multi hub 3PL?

A multi hub 3PL is a third party logistics provider that holds your inventory across two or more fulfilment centres and allocates each order to whichever site reaches the customer fastest or most cheaply. A single hub 3PL runs one warehouse on your behalf. The difference sounds technical. Commercially it is the gap between a two day delivery promise and a five day one.

That distinction matters more here than in almost any comparable market. Demand is concentrated on the east coast. The landmass is not. A well placed Sydney or Melbourne site reaches a large share of the population inside two working days. Perth sits four to seven days away by road.

Five signs direct fulfilment has reached its ceiling

Merchants feel these before they can measure them. If three or more sound familiar, the model is already under strain.

You are renting space you cannot use properly. Mezzanine floors, shipping containers in the yard and a second short term lease across town are symptoms of a site that has outgrown its footprint, not a business that needs more square metres.

Pick and pack accuracy is slipping. Error rates climb with SKU count rather than order volume. When your mispick rate moves the wrong way despite a stable team, the layout is the problem.

Peak season runs on casual labour. If November and December depend on inducting temporary staff into a complex process, you are paying a training premium annually for capacity you use for eight weeks.

Delivery promises vary by postcode. Quoting three days to Sydney and seven to Perth from a single site is a conversion problem, not a logistics one. Last Mile Delivery performance is where most single site models visibly fail.

Founders are still in the warehouse. The clearest signal of all. Senior time spent packing cartons is time not spent on merchandising, acquisition or margin.

The numbers that signal it is time to move

Symptoms are useful. Numbers are actionable. Four measures are worth tracking monthly.

1. Cost per order, fully loaded. Include rent, labour, packaging, equipment finance, software, insurance, shrinkage and your own time at a realistic hourly rate. Most merchants who run this calculation honestly find their true cost per order is 20 to 40 per cent higher than they assumed, because idle capacity and management time never appear on the invoice.
2. Order volume against site capacity. There is no universal switching point, but the economics of outsourcing usually start working between 1,000 and 3,000 orders a month, and become hard to argue with above that. The figure depends far more on product size and SKU count than on order count alone.
3. Delivery lead times by state. Map your actual transit times to Sydney, Melbourne, Brisbane, Adelaide, Perth and regional postcodes. Australia Post research found that 26 per cent of shoppers expect same or next day delivery when an order is urgent, and 69 per cent want a choice of delivery options at checkout. THE ICONIC has reported a conversion drop of between 3 and 10 per cent for every additional day of delivery time.
4. Where your customers actually are. This one surprises people. The highest delivery volume postcode in 2025 was Toowoomba in Queensland, followed by Mackay and Point Cook in Victoria. Demand density is not confined to inner metro areas. Node placement should follow the parcels, not the population headline.

How many fulfilment nodes does an Australian merchant need?

More nodes is not automatically better. Every site adds safety stock, working capital and complexity. The right answer is usually one of three.

One hub, well placed. Suitable for merchants under roughly 2,000 orders a month with a concentrated east coast customer base. A Sydney or Melbourne site covers the majority of demand at acceptable transit times. NSW alone accounted for $26.4 billion of online spend in 2025, or one in every three dollars spent online nationally, on CommBank iQ figures cited by Australia Post.

Two hubs, east and west or north and south. The most common upgrade. A Sydney or Melbourne primary paired with a Perth or Brisbane secondary removes the worst of the lead time penalty without doubling inventory. Fast moving lines are held in both. Slow movers stay central. B dynamic Logistics sets up this kind of multi-state stock positioning regularly, and assigns a dedicated account contact to manage the split as your velocity data changes.

Full national coverage. Justified when volume, delivery expectations or product weight make long lanes prohibitive. A provider with existing sites across Sydney, Melbourne, Brisbane, Adelaide and Perth changes the arithmetic here, because you rent into an established network rather than building one. B dynamic Logistics operates on that footprint, with presence in New Zealand.

The practical rule: split inventory by velocity, not evenly. Your top 20 per cent of SKUs justify duplication. The tail does not.

Node count is a customer experience decision as much as a freight one. Australia Post found three in four shoppers say a good delivery experience makes them shop online more often. A promise met consistently is worth more than a faster one broken occasionally.

What outsourcing actually costs against running your own site

The honest comparison is fixed cost against variable cost, and it has shifted in the past 18 months.

Prime industrial net face rents in the first quarter of 2026 sat at roughly $228 per square metre in Western Sydney, $187 in Brisbane, $164 in Perth, $147 in Adelaide and about $144 in Melbourne, on Knight Frank figures. Leasing incentives have also risen sharply, reaching close to 22 per cent in Western Sydney and 20.5 per cent in Melbourne, which means effective rents are materially below face rents in those markets right now.

That softening is real and it does make holding your own site cheaper than it was. It does not change the structure of the decision. A lease is a fixed commitment across five or seven years. Fulfilment charged per order is variable. If your volume is seasonal, uneven or genuinely uncertain, converting a fixed cost into a variable one is worth paying a margin for.

Costs merchants routinely omit: forklift finance and servicing, warehouse management software, public liability and stock insurance, shrinkage, workers compensation, and capacity sitting idle for ten months of the year.

The freight side often settles the argument. A 3PL consolidating volume across many clients buys carrier rates no single mid sized merchant can access. Providers such as B dynamic Logistics allocate each consignment across a multi carrier network under a Transportation and Multi Carrier Solutions model rather than defaulting to one contract, and pair that with Warehousing and eCommerce Fulfilment under a single per order charge.

One margin pressure is worth naming. The average Australian online basket has fallen to $96, roughly $10 lower than in 2020, as shoppers spread spending across more brands. Smaller baskets mean freight and handling consume a larger share of every order. A fulfilment cost that was defensible at a $130 average order value can become the difference between a profitable line and a break even one at $96. Review cost per order quarterly, not annually.

How to move without disrupting trading

Migration is the objection that stalls most decisions, reasonably so. A staged approach removes most of the risk.

1. Integrate systems first, move stock second. Connect your platform to the provider’s warehouse management system and run it in parallel for two to four weeks before a single pallet moves. B dynamic Logistics runs this parallel period through its BDL Advantage platform, so you can see stock and order data from both sites side by side before committing to the cutover.
2. Start with a single channel or SKU group. Move your fastest moving lines first. They generate the data you need and expose problems while volume is still recoverable.
3. Use cross docking during changeover. Drop Shipping and Cross Dock arrangements let inbound stock be redirected to the new site and dispatched without ever entering your old one, which shortens the overlap period.
4. Move in the trough, never the peak. February to April is the sensible window for most Australian retailers.
5. Agree the service levels in writing. Dispatch cut off times, pick accuracy targets, inbound turnaround and reporting cadence belong in the agreement, not in an email thread. Established operators such as B dynamic Logistics will put these in a schedule without being asked. Treat reluctance as information.

Oversized products deserve separate treatment. Furniture, whitegoods, machinery and agricultural equipment cannot run through parcel networks at all, and require dedicated handling capability including forklifts, cranes and specialised trailers. Merchants in these categories should assess big and bulky capability specifically rather than general fulfilment credentials, and ask to see the Specialised Machinery and Equipment on site before signing anything. B dynamic Logistics runs a dedicated big and bulky division for exactly this category, with the equipment and trained crews oversized freight requires.

The bottom line

The trigger for moving to a multi hub 3PL is rarely a single number. It is the point where capacity strain, geographic reach and cost per order start pointing the same way at once. Run the fully loaded cost calculation, map your transit times by state, and check where your parcels are actually going. If two of those three work against you, the model has already changed underneath you. Providers including B dynamic Logistics will model those numbers against an existing national network before you commit, which is a cheaper way to test the case than another peak season spent finding out.

Frequently Asked Questions

Ten questions Australian merchants ask most often when weighing up a move.

Q1: At what order volume does moving to a 3PL usually make financial sense?

There is no fixed threshold, but the economics commonly start to favour outsourcing between 1,000 and 3,000 orders a month. Product size, SKU count and geographic spread matter more than order count on its own. A merchant shipping bulky furniture may benefit at 300 orders a month, while a small parcel business might comfortably self fulfil at 4,000.

Q2: What is the difference between a single warehouse 3PL and a multi hub 3PL?

A single warehouse 3PL runs one facility for you. A multi hub 3PL holds inventory across several sites and routes each order from whichever location serves the customer best. The second model reduces transit times and freight costs, but requires more sophisticated inventory planning.

Q3: Will splitting inventory across sites increase my stock holding?

Yes, to a degree. Each node needs its own safety stock, so total inventory typically rises. The offset comes from lower freight costs and faster delivery, which usually improves conversion. Duplicating only your fastest moving lines keeps the working capital increase manageable.

Q4: How long does migration from in house fulfilment to a 3PL take?

Six to twelve weeks is typical for a mid sized merchant. Systems integration accounts for most of that. Physical stock movement, if sequenced properly, can be completed within a fortnight without pausing trading.

Q5: Can a 3PL handle oversized or heavy products?

Some can. Many cannot. Parcel oriented facilities lack the racking, equipment and trained crews that furniture, whitegoods and machinery require. Ask specifically about forklift and crane capability, cantilever or drive in racking, and two person delivery crews before assuming an oversized capability exists.

Q6: How does a multi hub model improve delivery times to Perth and regional Australia?

By holding stock closer to the customer. A Perth node converts a four to seven day road transit from the east coast into a next day or two day metro delivery. For regional postcodes, the gain is usually one to three days plus a reduction in remote area surcharges.

Q7: Do I lose control of the customer experience when I outsource?

Not if the agreement is written properly. Branded packaging, insert cards, gift wrapping and custom labelling are standard value added services. What you do give up is direct oversight of the pick face, which is why pick accuracy and dispatch cut off times should be contracted service levels rather than assumptions.

Q8: What should I look for when comparing 3PL providers in Australia?

Node locations relative to your customer base, carrier network breadth, platform integrations already built, transparency of the pricing schedule, capability with your specific product type, and evidence of performance from existing clients in a comparable category.

Q9: How is 3PL pricing typically structured?

Most providers charge separately for inbound receipting, storage by pallet or cubic metre, pick and pack per order and per line, packaging consumables, and outbound freight. Watch for minimum monthly volumes, peak season surcharges and inbound handling rates, which is where quotes most often diverge from the eventual invoice.

Q10: Should I move everything at once or run both models in parallel?

Run in parallel wherever practical. Keeping your own site operating at reduced volume for four to six weeks gives you a fallback if integration issues surface, and the overlapping cost is almost always cheaper than a failed cutover during a trading period.
