Proximity to Customers vs. Suppliers

The location question in fulfillment is rarely an either-or decision. In practice, two goals compete: short delivery times for your customers and low procurement effort through short routes to suppliers. If you optimize for only one factor, pressure often increases on the other side of the supply chain. That is exactly why location selection needs a sound, data-driven logic instead of gut feeling.

This guide shows how to weigh proximity to customers and suppliers cleanly against each other, which metrics really matter, and how to make a viable decision for the next three to five years.

Why the trade-off is strategic

A warehouse location affects more than transport costs alone. It directly impacts:

• Delivery speed and customer satisfaction
• Inventory levels and capital tie-up
• Responsiveness during demand peaks
• Risk of delays in goods receipt
• Scalability during growth or channel expansion

Depending on the business model, weighting can vary significantly. D2C brands with high service promises often prioritize customer proximity. Import-heavy assortments with large volume frequently benefit from supplier proximity or port connectivity.

Decision logic: customer proximity or supplier proximity?

Basic principle

• Customer proximity reduces last-mile lead times, lowers SLA risks, and improves conversion and repeat purchase rate.
• Supplier proximity reduces inbound costs, shortens replenishment cycles, and stabilizes inventory.

The best choice emerges when you evaluate both sides in a shared target system. Individual averages are not enough. You need segmentation by product groups, shipping regions, and procurement channels.

Typical goal conflicts

1. Short customer distance often increases rent in metropolitan areas.
2. Supplier proximity in industrial clusters can worsen last-mile times.
3. A central location simplifies control but can jeopardize service promises in peripheral regions.
4. A decentralized approach improves delivery time but increases complexity and safety stock.

Metrics that support your decision

Customer side

• Share of orders per target region
• Target SLA (e.g. 24h or 48h)
• Average order value and margin per shipment
• Return rate by region
• Abandonment rate due to excessively long delivery time

Supplier side

• Origin clusters of top SKUs
• Replenishment time per supplier
• Minimum order quantities and delivery frequency
• Volume and weight drivers in inbound
• Disruption susceptibility (e.g. port, border, seasonality)

Shared control variables

Workflow: location decision in 6 steps

Three proven location strategies

1) Customer-proximate main location

Suitable for brands with a clear core target region and high delivery time pressure.

Advantages:

• Fast delivery in core markets
• High service quality with standard shipping
• Potentially lower last-mile costs in the target region

Risks:

• More expensive space and personnel
• Higher inbound costs from distant procurement regions

2) Supplier-proximate main location

Suitable for assortment-heavy providers with heavy, bulky, or inbound cost-intensive product ranges.

Advantages:

• Lower procurement costs
• Faster replenishment with high SKU breadth
• More stable product availability

Risks:

• Higher outbound costs to distant sales markets
• Harder to meet ambitious delivery time promises

3) Hybrid model with pre-distribution

One main warehouse near suppliers plus smaller regional pre-distribution or cross-dock points.

Advantages:

• Balance between inbound efficiency and customer proximity
• Better peak resilience

Risks:

• Higher process and system complexity
• More control effort for inventory and routing

Practical scoring matrix for location selection

Use a weighted point system. It is important that weights come from your strategy, not from habit.

Step by step to the decision

1. Define 3–5 location candidates based on your sales and procurement data.
2. Calculate inbound, warehouse, and outbound costs uniformly for each candidate.
3. Simulate SLA achievement for core regions and peak scenarios.
4. Assess risks (supplier failure, traffic, labor market, permits).
5. Make the decision only with clear abort criteria and target values.

Checklist: go-live readiness for location

• Cost model validated with at least 12 months of real-world data
• SLA simulation completed for at least 80 % of shipment volume
• Emergency plan for delivery disruptions and carrier bottlenecks documented
• Staff planning secured for peaks and sick days
• System integration for WMS, ERP, and carrier endpoints tested
• KPI set for the first 90 days defined bindingly

Common mistakes and how to avoid them

• Looking only at transport price: The total cost perspective including service effects is decisive.
• Not simulating peaks: Peak phases massively distort profitability.
• Overlooking regional demand: Averages conceal critical hotspots.
• Committing long-term too early: Pilot first, then long-term space decision.
• Underestimating system integration: Without clean data flows, even good locations lose impact.

Conclusion

The question "proximity to customers or proximity to suppliers" has no universal answer. Success comes to those who make the goal conflict transparent, evaluate with uniform metrics, and align the decision with both service and profitability. For many companies, not the extreme but a well-controlled hybrid model is the most stable path.
