What is a 3PL? Third-party logistics explained
A 3PL is an outsourced fulfilment partner.
Brands send them stock; the 3PL warehouses, picks, packs and ships on the brand's behalf.
A 3PL is an outsourced fulfilment partner.
Brands send them stock; the 3PL warehouses it, picks orders, packs, and ships under the brand's name.
Here is the honest definition and how the software stack actually works.
The one-line definition
A 3PL (third-party logistics provider) is an outsourced operations partner that handles warehousing, fulfilment, and shipping on behalf of brands that do not want to run their own warehouse. The brand sends inventory to the 3PL's facility; orders flow from the brand's storefront (Shopify, marketplaces, B2B portal) to the 3PL's WMS; the 3PL picks, packs, and dispatches under the brand's name and packaging.
The defining shape: the brand owns the inventory and the customer relationship; the 3PL owns the warehouse and the workflow.
What a 3PL actually does
- Receives inbound stock against PO
- Stores and tracks inventory at bin-level
- Receives orders from the brand's storefront and marketplaces
- Picks, packs, and dispatches under the brand's packaging
- Handles returns receiving and disposition
- Books carrier pickups and submits manifests
- Reports KPIs back to the brand (throughput, accuracy, dispatch SLA)
What a 3PL is not
A 3PL is not the brand's ecommerce platform — Shopify, WooCommerce, marketplaces stay on the brand's side. A 3PL is not the brand's OMS — order routing across channels is usually still the brand's decision. A 3PL is not the brand's finance system — inventory ownership and revenue stay on the brand's books.
3PLs sometimes get called "4PL" or "5PL" providers when they take on broader scope (4PL = logistics orchestration across multiple 3PLs; 5PL = strategic supply chain partner). For most ANZ operators, "3PL" is the right term.
When does a brand use a 3PL?
The honest triggers:
- Order volume has outgrown the founder's garage or warehouse
- The brand wants to expand to a new region without opening a warehouse there
- Capital allocation favours marketing and product over operations
- Fulfilment quality matters but is not the brand's differentiator
- Seasonal volume spikes (Black Friday, Christmas) need flex capacity
Brands that run their own fulfilment ("in-house" or "1PL") usually do so because the customer experience around dispatch IS the differentiator — custom packaging, white-glove delivery, founder-signed cards.
The 3PL software stack
A modern 3PL runs on a WMS designed for multi-client operations. The key requirements:
- Client isolation — each brand's inventory is segregated; one brand's stock cannot bleed into another's order
- Per-client billing — storage fees, pick fees, pack fees, value-added service charges all tracked per brand
- Channel integrations — the WMS receives orders from each brand's Shopify / WooCommerce / marketplaces
- Reporting per client — each brand gets a self-serve dashboard
- Receiving by ASN — inbound stock is matched against advance ship notices, not improvised
3PL software options in ANZ
Three common shapes:
- Dedicated 3PL WMS — Mintsoft, SoftEon, Logiwa, Cin7 Omni at the upper-SMB end. Built specifically for multi-client ops.
- Modular ERP with 3PL capability — OpsUI, NetSuite OneWorld with WMS+. Treats 3PL as a client-isolation pattern within a broader ops product.
- Enterprise WMS — Manhattan, Blue Yonder, Korber for 3PLs above ~50,000 orders/day. Heavy implementation, deep capability.
For ANZ 3PLs serving SMB and lower-mid-market brands, the OpsUI shape is usually the cheapest path — modular pricing means a small 3PL can start with Inventory + Warehouse + Shipping modules and add CRM, Analytics, or Finance as the operation grows.

Frequently asked
What does 3PL stand for?
3PL stands for third-party logistics. A 3PL is an outsourced operations partner that handles warehousing, fulfilment, and shipping on behalf of brands that do not want to run their own warehouse. The brand owns the inventory and the customer relationship; the 3PL owns the warehouse and the workflow.
What is the difference between a 3PL and a fulfilment centre?
In practice, they are usually the same thing. "Fulfilment centre" is the more retail-friendly term (made common by Amazon FBA). "3PL" is the logistics industry term and tends to imply a broader service scope — possibly including kitting, light assembly, returns processing, and value-added services beyond just pick-and-pack.
How much does using a 3PL cost?
A 3PL typically bills per transaction — receiving fees, storage fees per cubic metre per month, pick fees per line, pack fees per order, plus shipping cost. Realistic ANZ ranges for SMB brands: receiving NZ$5–15 per pallet, storage NZ$15–40 per cubic metre per month, pick NZ$1.50–4 per line, pack NZ$2–6 per order. A 500-order/month brand typically pays NZ$2,000–5,000/month all-in.
Is a 3PL the same as a freight forwarder?
No. A freight forwarder moves goods between locations (origin to port to destination); a 3PL stores and ships individual orders from a warehouse. Some companies do both, but the 3PL function is fulfilment, while the freight forwarder function is movement. For ANZ brands importing from China, you usually have one of each in the stack.
What software do 3PLs use in ANZ?
The three common shapes: dedicated 3PL WMS (Mintsoft, SoftEon, Logiwa, Cin7 Omni), modular ERP with 3PL capability (OpsUI, NetSuite OneWorld with WMS+), or enterprise WMS (Manhattan, Blue Yonder, Korber) for 3PLs above ~50,000 orders/day. For ANZ 3PLs serving SMB and lower-mid-market brands, the modular ERP shape is usually the cheapest path.
