Step 1: Data Structuring
Create a sheet with raw vendor data. Example columns:
| Vendor ID | Vendor Name | Total Units | QC Failed Units | Total Orders | Refunded Orders | Orders Shipped On Time |
|---|---|---|---|---|---|---|
| V-101 | Alpha Supplies | 500 | 15 | 200 | 10 | 185 |
KAKOBUY Spreadsheet: How to Automate Seller Performance Scoring
2026-02-04
A Guide to Creating Weighted Formulas for Vendor Ranking
Managing a multitude of vendors efficiently is crucial for e-commerce platforms like KAKOBUY. Manually tracking each seller's performance is time-consuming and prone to error. By leveraging a powerful KAKOBUY Performance Spreadsheet
Core Performance Metrics (The Ranking Pillars)
Your scoring system should be built on quantifiable, objective data. For KAKOBUY, we recommend focusing on these three critical areas:
- Quality Control (QC) Fail Rate:
- Refund Rate:
- Shipping Reliability Score:
- Refund Rate:
Building Your Automated Scoring System
Step 2: Calculate Base Metrics
Add calculation columns (formulas automate this):
- QC Score:=1 - (QC Failed Units / Total Units). Example: 1 - (15/500) = 0.97
- Refund Score:=1 - (Refunded Orders / Total Orders). Example: 1 - (10/200) = 0.95
- Shipping Score:=Orders Shipped On Time / Total Orders. Example: 185/200 = 0.925
Each score is now a value between 0 and 1.
Step 3: Create the Weighted Master Formula
This is the core of automation. Assign weights (totaling 100%) based on importance to KAKOBUY. For instance:
- Quality (QC):
- Reliability (Shipping):
- Customer Resolution (Refunds):
- Reliability (Shipping):
The Overall Performance Score
Example for Alpha Supplies: (0.97*0.5) + (0.925*0.3) + (0.95*0.2) = 0.485 + 0.2775 + 0.19 = 0.9525
Overall Score = (QC Score * 0.5) + (Shipping Score * 0.3) + (Refund Score * 0.2)
Step 4: Automate Ranking & Visualization
Use spreadsheet functions to auto-rank vendors:
- Add a Rank=RANK([Overall Score Cell], [Range of All Overall Scores])
- Apply Conditional Formatting
- Create a Dashboard SheetSORT()
