Top 5 KPIs Every Fashion Brand Should Track in Their Supply Chain
As the fashion industry becomes more global and consumer expectations rise, supply chain management can no longer rely on instinct or outdated metrics. To stay agile, ethical, and profitable, fashion brands must ground their decisions in real-time, measurable data. Key Performance Indicators (KPIs) help supply chain teams evaluate what’s working — and flag what’s not — before small inefficiencies balloon into costly delays or reputational damage.
Here’s what every forward-thinking fashion brand should be tracking — and why these KPIs matter now more than ever.
Operational Precision: On-Time Delivery
Consistent delivery performance is a hallmark of supply chain maturity. Tracking on-time delivery doesn’t just help reduce last-minute air freight or missed season launches — it also reveals hidden issues with upstream suppliers or freight partners.
A recent report by McKinsey & Company emphasizes that the most resilient fashion supply chains maintain over 95% on-time delivery, even during high-volatility periods like peak season or geopolitical disruption.
Agility Metric: Supplier Lead Time
Supplier lead time — the average number of days from order to delivery — defines how quickly your brand can respond to market shifts. In today’s fast fashion and micro-season environment, shaving even a few days off lead times can significantly increase responsiveness and reduce inventory risk.

Quality Assurance: First Pass Yield (FPY)
First Pass Yield measures how many units pass inspection without needing rework or rejection. It's a gold standard for quality control. Low FPY could indicate training gaps, poor raw material quality, or misaligned expectations between buyers and factories — all of which can lead to costly delays or product returns.
A high FPY score means smoother production runs and fewer surprises — essential for on-time delivery and brand reputation.
Financial Health: Inventory Turnover Ratio
Inventory Turnover reflects how many times inventory sells and is replaced during a period. It’s a direct indicator of product-market fit, demand planning accuracy, and supply chain responsiveness. A sluggish turnover suggests either overproduction or misaligned forecasting.
Brands aiming for data-driven planning can explore how Zara maintains strong turnover through integrated planning and just-in-time production (Harvard Business Review).
Sustainability Score: Supplier ESG Compliance Rate
Sustainability is now more than a branding choice — it’s a commercial and regulatory requirement. One key KPI is ESG (Environmental, Social, Governance) compliance among your suppliers. Whether it’s ensuring proper labor standards or tracking emissions, having a clear view into which suppliers are aligned can make or break your ESG strategy.
More on supplier ESG readiness can be found in this Earth.org overview on fashion supply chain ethics, which highlights current risks in unmonitored sourcing regions.
Conclusion
Tracking the right KPIs empowers fashion brands to move faster, cut costs, meet compliance standards, and build longer-lasting partnerships with their suppliers. These five metrics — on-time delivery, lead time, FPY, inventory turnover, and ESG compliance — should be the foundation of any modern supply chain dashboard.
You don’t need to measure everything. But you do need to measure what matters.
