• Cost of quality failures or rework

Case Study: PCB Assembly Pricing Across Suppliers

For example, when sourcing PCB assemblies, three Shenzhen-based suppliers were quoted for a batch of 2,000 units:

Supplier	Unit Price (USD)	MOQ	Lead Time	Additional Notes
Hongrong (shenzhen) Electronics Co., Ltd.	$4.20	500	12 days	Included free design review and DFM report
Toptek Pcb Co., Limited	$3.85	1,000	15 days	No customization support; standard designs only
Zhixinda Electronics (Shenzhen) Co., Ltd.	$4.50	300	10 days	Offered full turnkey solution with component sourcing

In this scenario, while Toptek offered the lowest price, their lack of flexibility and longer lead time made them less suitable for complex projects. Hongrong provided a balanced mix of cost, responsiveness, and added engineering value. Zhixinda justified its premium with faster turnaround and comprehensive services—ideal for urgent or full-service builds.

This illustrates that the lowest price does not always equate to the best value. Procurement teams should adopt a Total Cost of Ownership (TCO) approach, factoring in speed, service, risk mitigation, and lifecycle support.
