CNFANS: How to Automate Seller Ratings Using Spreadsheet Formulas
In e-commerce platforms like CNFANS, maintaining accurate seller ratings is crucial for building trust and ensuring marketplace quality. Manual calculations are time-consuming and prone to errors. This guide will show you how to create auto-calculating performance scores using simple spreadsheet formulas based on reliability metrics and refund ratios.
Prerequisites
- Basic spreadsheet software (Excel, Google Sheets, or similar)
- Seller performance data including:
- Total orders completed
- Orders delivered on-time
- Total refund requests
- Refunds processed
Defining Your Rating Metrics
Reliability Ratio
Measures how consistently sellers deliver orders on time.
Refund Ratio
Indicates the percentage of orders that resulted in refunds.
Building the Automated Rating System
Step 1: Set Up Your Data Structure
Organize your spreadsheet with the following columns:
| Seller Name | Total Orders | On-time Deliveries | Refunded Orders | Reliability Ratio | Refund Ratio | Performance Score |
|---|---|---|---|---|---|---|
| Seller A | 150 | 138 | 12 | 92% | 8% | 84 |
Step 2: Calculate Reliability Ratio
In the Reliability Ratio column, use this formula:
Where C2 is On-time Deliveries and B2 is Total Orders.
Step 3: Calculate Refund Ratio
In the Refund Ratio column, use this formula:
Where D2 is Refunded Orders and B2 is Total Orders.
Step 4: Create Performance Score
The performance score combines both metrics with weighted importance:
This formula weights Reliability at 70% and Refund avoidance at 30%. Adjust weights based on your business priorities.
