Price Comparison and Value-Based Decision Making

Pricing varies significantly among suppliers based on scale, location, customization level, and included services (e.g., tooling, firmware development, certification support). While cost is important, focusing solely on unit price can lead to hidden expenses related to rework, delays, or non-compliance.

Case Study: Comparing Quotations for 5,000 Units

Suppose you're sourcing a mid-tier iOS-compatible smartwatch with heart rate monitoring, IP68 rating, and stainless steel casing. Here’s how different suppliers might quote:

Supplier	Unit Price (FOB)	MOQ Flexibility	Included Services	Lead Time
Zhejiang Zhuoyue Electronics	$24.50	High (negotiable down to 3k)	Firmware dev, MFi prep, SGS testing	50 days
Shenzhen Lemons SLMM Technology	$19.80	Medium (min 2k)	Basic firmware, no compliance testing	60 days
ShenZhen ZTX Technology	$22.00	Low (fixed at 5k)	Custom UI, RoHS only	55 days

At first glance, Shenzhen Lemons SLMM Technology Co., Ltd. appears to offer the lowest price. However, the absence of MFi preparation and third-party testing could result in additional costs of $15,000+ if outsourced later. Moreover, longer lead times increase inventory financing costs.

In contrast, Zhejiang Zhuoyue Electronics offers a higher upfront cost but includes critical value-added services that reduce risk and accelerate time-to-market. For regulated markets like the EU or North America, this bundled compliance support can be invaluable.

This example underscores the importance of evaluating total cost of ownership—not just per-unit price—when selecting a supplier.
