In the dynamic world of sourcing, a seller's past performance is your most reliable predictor of future reliability. By systematically analyzing historical data, you can move beyond guesswork and build a network of consistently trustworthy partners. This guide outlines a practical method for comparing seller accuracy using your past Quality Control (QC) and shipping logs.

Key Metrics for Tracking Seller Consistency

| On-Time Shipping Rate (%) | (Number of orders shipped on or before promise date / Total orders) * 100 | Reliability in logistics and supply chain management. |
| Defect Frequency | Average number of major/minor defects per QC report over time. | Whether quality control is improving, stable, or deteriorating. |
