The lowest unit price is frequently the highest total cost. Total cost of ownership (TCO) sourcing captures the quality, logistics, and risk costs that unit price hides.
What Unit Price Hides
Freight, tariffs, quality escapes, expediting, carrying cost, and supplier risk all live outside the quoted price. A cheaper part that fails inspection or arrives late costs more than a pricier reliable one.
Building a TCO Model
Add landed cost, quality cost (scrap, rework, RMA), lead-time and carrying cost, and a risk premium for single-source or distant suppliers. Compare suppliers on total cost, not quoted price.
When Local Wins
Local strategic sourcing often wins on TCO even at a higher unit price — lower freight, shorter lead times, less buffer inventory, and easier quality management. We have documented seven-figure annual savings from local resourcing.
Key Takeaways
- Lowest unit price is often highest total cost.
- Model landed, quality, carrying, and risk costs together.
- Local sourcing frequently wins on TCO despite higher unit price.
