KAKOBUY: How to Use Spreadsheet Metrics to Identify High-Risk Vendors

2025-11-26

Flag sellers with frequent QC failures, delayed shipments, or excessive refund rates for attention

By KAKOBUY Quality Assurance Team Updated: December 2023

In today's competitive e-commerce landscape, effective vendor management is crucial for maintaining product quality, customer satisfaction, and business reputation. At KAKOBUY, we've developed a systematic approach to identify potential high-risk vendors using simple spreadsheet metrics that every team can implement.

Three Critical Vendor Performance Metrics

1. Quality Control Failure Rate

Calculate the percentage of shipments that fail quality inspection:

QC Failure Rate = (Failed Inspections ÷ Total Inspections) × 100

Low Risk:
Medium Risk:
High Risk:

2. Shipment Delay Rate

Track the frequency of late deliveries against promised timelines:

Delay Rate = (Delayed Shipments ÷ Total Shipments) × 100

Low Risk:
Medium Risk:
High Risk:

3. Customer Refund Rate

Monitor refund requests due to product issues or dissatisfaction:

Refund Rate = (Refunded Orders ÷ Total Orders) × 100

Low Risk:
Medium Risk:
High Risk:

Creating Your Vendor Assessment Spreadsheet

Vendor ID Vendor Name QC Failure Rate Shipment Delay Rate Refund Rate Risk Score Action Required

VEN-001 Alpha Suppliers 1.2% 3.1% 2.4% Low Monitor

VEN-002 Beta Manufacturers 4.7% 15.3% 5.2% High Immediate Review

VEN-003 Gamma Trading 8.9% 7.8% 12.1% High Consider Replacement

Proactive Risk Management Steps

Step 1: Data Collection

Gather data from your QC reports, shipping logs, and customer service records. Update your spreadsheet weekly to ensure timely identification of issues.

Step 2: Calculate Comprehensive Risk Score

Assign weights to each metric based on business priorities and calculate an overall risk score:

Risk Score = (QC Rate × 0.4) + (Delay Rate × 0.3) + (Refund Rate × 0.3)

Step 3: Implement Traffic Light System

Color-code vendors in your spreadsheet:

Step 4: Regular Vendor Reviews

Conduct monthly performance reviews with medium and high-risk vendors. Document improvement plans and track progress.
