Step 2: Price Reliability Evaluation
Price_Reliability_Score = (Price_Accuracy + Shipping_Cost_Transparency + Total_Value) / 3
- Final Price Accuracy
- Shipping Cost Transparency
- Overall Value Assessment
- Shipping Cost Transparency
Step 3: Communication Effectiveness Scoring
Communication_Score = (Response_Time + Query_Resolution + Language_Clarity) / 3
- Response Time Rating
- Query Resolution Effectiveness
- Communication Clarity
- Query Resolution Effectiveness
Step 4: Overall Seller Performance Calculation
Overall_Score = (QC_Accuracy×0.4) + (Price_Reliability×0.3) + (Communication×0.3)
This weighted calculation provides a balanced view of seller performance across all critical dimensions.
Long-Term Strategic Insights
✅ Performance Trend Analysis
Track seller rating evolution over 6-12 month periods to identify improvement or decline patterns. Create time-series charts to visualize performance trajectories.
✅ Supplier Comparison Matrix
Compare multiple sellers across identical product categories to identify your most reliable partners for specific item types.
✅ Risk Mitification Strategy
Establish minimum threshold scores for repeat purchases and flag sellers falling below your quality standards.
Spreadsheet Implementation Code
Google Sheets/Excel Formula for Overall Score:
= (B2*0.4) + (C2*0.3) + (D2*0.3)
Where B2=QC_Accuracy, C2=Price_Reliability, D2=Communication_Score
Conditional Formatting Rule for Performance Tiers:
=IF(E2>=4.5,"Premium",IF(E2>=3.5,"Standard","Review Required"))
Apply color coding: Green ≥4.5, Yellow 3.5-4.4, Red <3.5
