Supply chain distribution is the movement and storage of finished goods from the point of production to the customer, through a distribution network of warehouses, transport links and sales channels. It determines how fast, how reliably and at what cost products reach the market.
Designing it means choosing channels, network shape and transport modes that balance service against cost.
Distribution channels
- Direct: the manufacturer sells and ships to the end customer, for example through its own website.
- Indirect: goods pass through wholesalers, distributors or retailers before reaching the customer.
- Hybrid: a mix, such as selling online directly while also supplying retail partners.
Direct channels give control and customer data but require fulfillment capability. Indirect channels extend reach and reduce handling for the manufacturer, but add margin layers and reduce visibility.
Network structures
| Structure | Description | Trade-offs |
|---|---|---|
| Centralised | One or few large distribution centres | Lower inventory and fixed cost, longer delivery distances |
| Decentralised | Many regional sites near customers | Faster delivery, higher total inventory and cost |
| Hub and spoke | Central hub feeds regional depots | Efficient consolidation, extra handling step |
| Cross-docking | Goods move from inbound to outbound with little storage | Less storage, needs tight scheduling and coordination |
| Direct shipment | Supplier ships straight to the customer | Fewer touches, limited control over service |
Transport modes
Each mode has a typical role. Trucking is flexible and covers most domestic distribution. Rail suits heavy, long-distance freight at lower cost per tonne but slower and less flexible. Ocean carries bulk international volume at low cost with long transit times. Air is fast and expensive, used for urgent or high-value goods. Parcel and courier services handle small shipments to homes and businesses. Many distribution plans combine modes, called intermodal transport, for example rail for the long leg and truck for the final delivery.
In Canada, long distances, winter conditions and the relatively small number of large population centres make rail and consolidated long-haul trucking significant, with cross-border flows to the United States an important part of many networks.
Designing a distribution plan
- Set service levels by customer segment, such as delivery time and order cut-off.
- Map demand by location and product type.
- Compare network options on transport, storage and handling cost together.
- Choose modes and carriers for each lane.
- Decide which parts to run directly and which to outsource.
- Track results and revisit the design when demand shifts.
Cost and service trade-offs
Faster and more frequent delivery generally raises transport cost and may require more stock held near customers. Consolidating shipments lowers transport cost per unit but slows delivery. Total cost thinking, which counts transport, warehousing, inventory and service failures together, avoids optimizing one cost at the expense of another.
Where AI and analytics help
Route optimization, load planning, demand forecasting by region and delivery-time prediction are established uses. Network design tools model scenarios across sites and modes. Results depend on data quality and on realistic assumptions, and the models support decisions rather than replace judgment about service policy.
Checklist
- Are channels matched to customer needs and margins?
- Is the network tested against demand growth and disruption?
- Are carrier performance and costs reviewed regularly?
- Is shipment tracking visible to both the business and its customers?
Common questions
What is the difference between logistics and distribution?
Logistics covers the planning of the flow of goods and information in general, including inbound supply. Distribution focuses on outbound movement of finished goods to customers.
What is a distribution centre?
A facility that receives goods, stores them briefly and ships them to stores, other sites or customers. It focuses on throughput rather than long-term storage.
