A warehousing strategy is the plan for how many warehouses a business needs, where they sit, whether it owns or outsources them, how they are laid out, and how much automation they use. It links storage decisions to customer service goals, inventory levels and total logistics cost.
Good strategy starts with demand and service needs, not with a building.
The main decisions
- Number of sites. More sites bring stock closer to customers and shorten delivery, but raise inventory and fixed costs.
- Location. Proximity to customers, suppliers, ports, highways and labour all matter.
- Ownership model. Own, lease, or use a third-party logistics (3PL) provider.
- Role of each site. Central distribution, regional fulfillment, cross-dock, returns or overflow.
- Layout and storage type. Pallet racking, shelving, bulk floor storage, cold storage and so on.
- Automation level. From manual with scanners to conveyors, shuttles and mobile robots.
Owned, leased or outsourced
| Model | Advantages | Trade-offs |
|---|---|---|
| Owned | Full control, can be tailored to operations | Large capital commitment, hard to scale down |
| Leased | Lower upfront cost, some flexibility on term | Rent exposure, you still run the operation |
| 3PL, dedicated | Provider runs the site for one customer | Contract commitment, less direct control |
| 3PL, shared | Pay per use, flexible capacity | Shared resources, less customisation |
A step-by-step approach
- Define service goals. Delivery times, order cut-offs and fill rates by customer segment.
- Profile demand and products. Volumes by region, order profiles, size and weight, handling needs, seasonality.
- Model network options. Compare scenarios with different numbers and locations of sites using transport, storage and handling costs.
- Select the operating model. Decide what to own, lease or outsource.
- Design each site. Capacity, layout, equipment and systems.
- Plan the transition and review regularly. Demand shifts, so a network that worked once may need adjustment.
Location factors
Transport cost is usually the main driver, which pulls sites toward demand centres and transport hubs. Other factors include land and labour availability, local wages, municipal regulation, climate and resilience to disruption. For Canada, long distances and a spread-out population often lead to a smaller number of hubs near large metropolitan areas, supported by regional partners for remote areas. Cross-border flows add customs and trade-agreement considerations, such as those under CUSMA.
Automation: how much fits
Automation helps when volumes are high, stable and predictable, labour is scarce, and the product range suits the equipment. It is less suitable when volumes swing widely, products vary a great deal, or the business is likely to change locations or models soon. Phasing in automation, starting with scanning, sortation or conveyor sections, lowers risk compared with a single large installation.
Where AI and analytics help
Network modelling tools compare site options; demand forecasts inform capacity plans; slotting analysis suggests storage locations. Results depend on data quality and on assumptions about costs and demand, which should be tested with several scenarios rather than a single forecast.
Checklist for reviewing a warehousing strategy
- Do service goals drive the network design, and are they written down?
- Has the design been tested against higher and lower demand?
- Are lease terms and 3PL contracts aligned with how long the plan is expected to hold?
- Is there contingency capacity if a site is disrupted?
- Are decisions reviewed on a regular schedule?
Common questions
How many warehouses does a business need?
There is no standard number. It depends on customer locations, delivery promises, product value and transport costs. Network modelling helps compare options.
Is a 3PL cheaper than running a warehouse?
Not always. A 3PL can lower fixed costs and add flexibility, but fees, minimums and management of the relationship need to be compared against the cost of running the site directly.
