Marketplace Seller Grading System
Objective performance evaluation system that scores sellers on delivery, satisfaction, inventory, and compliance metrics to determine marketplace status.
Solution
This automated grading system objectively evaluates marketplace seller performance using key operational metrics. It scores sellers on four critical dimensions: on-time delivery rate, customer satisfaction ratings, inventory accuracy, and policy compliance. Each metric is assessed against industry-standard thresholds and assigned a 1-5 point score.
The system automatically identifies seller strengths and improvement areas by analyzing performance patterns. Based on the aggregate score calculation, sellers receive a letter grade (A-F), performance status, and specific recommended actions. Top performers gain premium status with enhanced visibility, while underperforming sellers receive targeted improvement plans. This creates a fair, transparent framework that motivates sellers to maintain high standards while giving marketplace administrators clear insights for partner management.
How it works
The decision system follows a structured evaluation process:
- Data Collection: Processes seller performance metrics and account information from the marketplace platform.
- Individual Metric Scoring: Evaluates each performance indicator against defined thresholds:
- On-time delivery (≥98% = 5 points, scaling down to <85% = 1 point)
- Customer satisfaction (≥4.8 = 5 points, scaling down to <3.5 = 1 point)
- Inventory accuracy (≥99% = 5 points, scaling down to <85% = 1 point)
- Policy compliance (≥98% = 5 points, scaling down to <85% = 1 point)
- Score Aggregation: Calculates the average score across all metrics and identifies specific strengths (scores ≥4) and improvement areas (scores ≤2).
- Grade Assignment: Assigns letter grades based on the average score:
- A grade (≥4.5) = "Outstanding" with premium seller status
- B grade (≥3.5) = "Good" with featured seller status
- C grade (≥2.5) = "Satisfactory" with standard privileges
- D grade (≥1.5) = "Needs Improvement" requiring a performance plan
- F grade (<1.5) = "Poor" triggering account review
