In the competitive world of e-commerce, partnering with reliable suppliers is crucial. Manually tracking vendor performance is time-consuming and prone to error. The KAKOBUY Spreadsheet
To build an effective scoring system, you must first identify and track the key performance indicators (KPIs) that impact your business most. The KAKOBUY framework focuses on three pillars: The power of this system lies in creating a central spreadsheet that calculates a Weighted Total Score
Create columns for raw data for each vendor: Not all metrics are equally important. Decide on a weight for each category (e.g., QC: 50%, Refunds: 30%, Shipping: 20%). The total must equal 100%. The core weighted formula for each vendor row will look like this: This formula inverts negative rates (so lower failure rates score higher) and combines them into a single, comparable number, typically scaled from 0-100. Use spreadsheet functions to make this dynamic. For example: The KAKOBUY Spreadsheet
Start by defining your weights, structuring your data, and let the formulas do the ranking for you.The Core Metrics: What to Measure
Building Your Automated Scoring Engine
Step 1: Data Input & Normalization
QC_Failures, Units_Inspected, Refunds_Issued, Total_Orders, Late_Shipments, etc. Then, create calculated columns to normalize data into rates or scores (e.g., =QC_Failures/Units_Inspected).Step 2: Assigning Weights & Creating the Formula
Total_Score = (QC_Weight * (1 - QC_Failure_Rate)) +
(Refund_Weight * (1 - Refund_Rate)) +
(Shipping_Weight * Shipping_Reliability_Score)
Step 3: Implementation & Automation
