Pricing Strategies and Value-Based Sourcing

While cost is an important factor, focusing solely on price can compromise product longevity and system integration. Instead, adopt a total cost of ownership (TCO) approach when comparing suppliers.

Price vs. Value: A Real-World Example

Consider two scenarios:

• Supplier A (Low-Cost Option): Offers swing motors at $180/unit with 92.7% on-time delivery (Jining Haide International Trade Co., Ltd.). However, limited reorder rate (20%) and longer lead times suggest possible quality inconsistencies.
• Supplier B (Premium Option): Priced at $220/unit, Guangzhou Sailfish Machinery&Equipment Co., Ltd. delivers 99.9% on-time shipments and a 49% reorder rate—indicating higher satisfaction and fewer field failures.

Assuming 1,000 units annually:

Factor	Supplier A (Jining Haide)	Supplier B (Sailfish)
Total Unit Cost	$180,000	$220,000
Expected Failures (Est. 5% vs 1%)	50 units	10 units
Replacement & Downtime Cost ($500/unit)	$25,000	$5,000
Total Cost (Year 1)	$205,000	$225,000

Although Supplier B charges $40,000 more upfront, the reduced failure rate results in only a $20,000 net difference when factoring in downtime and warranty claims—plus significantly higher uptime and customer trust.
