Optimizing Your Sourcing: How to Rank KAKOBUY Sellers by QC Performance

2026-04-03

Selecting reliable suppliers is crucial for business success on platforms like KAKOBUY. This guide details a systematic method to rank and compare sellers using a weighted scoring system within a spreadsheet, focusing on three key performance indicators (KPIs).

The Core Performance Pillars

Our ranking model evaluates sellers based on three weighted criteria:

  • Inspection Success Rate (Weight: 50%): The most critical factor. This measures the percentage of shipments that pass quality control inspection without major defects.
  • Communication Speed (Weight: 30%): Reflects the seller's responsiveness to inquiries, issue resolution, and overall professionalism.
  • Delivery Punctuality (Weight: 20%): Tracks the seller's adherence to promised shipping or production deadlines.

Building the KAKOBUY Seller Ranking Spreadsheet

Step 1: Data Collection & Input

Create a table with the following columns for each seller:

Seller Name Inspection Pass Rate (%) Avg. Response Time (Hours) On-Time Delivery Rate (%) Weighted Score Rank
Sample Supplier A 95 2.5 98 -- --

Step 2: Normalizing Scores & Applying Weights

Convert different metrics to a consistent scale (e.g., 0-10) before applying weights.

Sample Calculation for "Supplier A":

Inspection Score: (95% / 100) * 10 * 0.50 = 4.75
Communication Score: Assume faster time is better. Formula: ((48 - 2.5) / 48)*10 * 0.30 ≈ 2.84
(Using a 48-hour benchmark for normalization)
Delivery Score: (98% / 100) * 10 * 0.20 = 1.96
TOTAL WEIGHTED SCORE: 4.75 + 2.84 + 1.96 = 9.55

Step 3: Automating the Rank
