Supply chain optimization is the backbone of any successful business, but for mid-market companies, balancing efficiency and growth can be particularly challenging. Key Performance Indicators (KPIs) play a crucial role in helping businesses track, measure, and improve supply chain performance. With the right KPIs, mid-market companies can uncover inefficiencies, make informed decisions, and achieve sustainable growth.
This blog explores the most essential KPIs for mid-market supply chain optimization, providing actionable insights on how to measure and improve these metrics.
Why KPIs Matter in Supply Chain Optimization
KPIs are measurable metrics that indicate how effectively a company achieves its key business objectives. For mid-market companies, supply chain KPIs provide:
- Visibility: Offer a clear view of supply chain performance across various functions.
- Efficiency: Highlight bottlenecks and inefficiencies, enabling targeted improvements.
- Strategic Insights: Support decision-making by identifying trends and forecasting future outcomes.
- Competitive Edge: Help businesses respond quickly to market changes and customer demands.
By focusing on relevant KPIs, mid-market companies can improve their operations while maintaining the flexibility needed to compete in dynamic markets.
Essential KPIs for Mid-Market Supply Chain Optimization
Below is a list of essential KPIs, each critical for achieving and maintaining supply chain efficiency.

1. On-Time Delivery (OTD)
- Definition: The percentage of orders delivered to customers on or before the promised date.
- Why It Matters: On-time delivery is a strong indicator of customer satisfaction. A delay in delivery can result in lost revenue and harm brand reputation.
- Formula:
OTD = (Orders Delivered on Time / Total Orders Delivered) × 100
- Strategies to Improve:
- Collaborate with logistics providers to minimize transit delays.
- Use technology for real-time tracking and proactive issue resolution.
- Optimize warehouse processes to reduce order cycle times.
2. Inventory Turnover
- Definition: The number of times a company sells and replaces its inventory over a specific period.
- Why It Matters: High inventory turnover reflects efficient inventory management and sales performance, while low turnover could indicate overstocking or low demand.
- Formula:
Inventory Turnover = Cost of Goods Sold (COGS) / Average Inventory Value
- Strategies to Improve:
- Implement demand forecasting tools to align stock levels with customer needs.
- Reduce obsolete inventory through regular reviews and markdown strategies.
- Adopt just-in-time (JIT) inventory practices to minimize holding costs.

3. Perfect Order Rate
- Definition: The percentage of orders delivered without any issues, including timeliness, accuracy, and completeness.
- Why It Matters: A higher perfect order rate demonstrates operational excellence and builds customer trust, reducing costly returns or rework.
- Formula:
Perfect Order Rate = (Perfect Orders / Total Orders) × 100
- Strategies to Improve:
- Invest in warehouse management systems (WMS) to enhance order accuracy.
- Regularly review and refine order-picking processes to eliminate errors.
- Conduct post-mortem reviews on problematic orders to identify improvement areas.
4. Freight Cost Per Unit
- Definition: The cost of shipping per unit of product.
- Why It Matters: Freight costs significantly impact profitability, making it essential to manage transportation expenses effectively.
- Formula:
Freight Cost Per Unit = Total Freight Costs / Units Shipped
- Strategies to Improve:
- Consolidate shipments to maximize truckload efficiency.
- Use transportation management systems (TMS) to optimize delivery routes.
- Negotiate long-term contracts with carriers for better pricing.
5. Days Sales of Inventory (DSI)
- Definition: The average number of days it takes to sell inventory.
- Why It Matters: A lower DSI indicates efficient inventory turnover, whereas a higher DSI may signal slow-moving products and excessive carrying costs.
- Formula:
DSI = (Average Inventory / COGS) × 365
- Strategies to Improve:
- Regularly analyze slow-moving inventory and plan promotions or markdowns.
- Use predictive analytics to anticipate demand fluctuations.
- Review supplier lead times to optimize replenishment cycles.

6. Return Rate
- Definition: The percentage of products returned by customers.
- Why It Matters: High return rates can indicate issues with product quality, fulfillment accuracy, or mismatched customer expectations.
- Formula:
Return Rate = (Total Returns / Total Orders Delivered) × 100
- Strategies to Improve:
- Improve product descriptions and images to reduce mismatched expectations.
- Enhance quality control processes to identify and eliminate defects before shipping.
- Offer better post-purchase support to resolve customer concerns and minimize returns.
