MyCNBox: Building a Seller Rating System in Your Spreadsheet

2026-03-15

Learn how to add objective scoring columns for reliability, communication, and quality control to rank and manage your suppliers effectively.

Why You Need a Seller Rating System

Managing multiple suppliers can be challenging. Without a structured system, it's easy to rely on gut feeling, leading to inconsistent decisions and potential risks. A Seller Rating System in your MyCNBox spreadsheet transforms supplier management into a data-driven, objective process. It helps you quickly identify top performers, flag underperformers, and make informed sourcing decisions.

Core Scoring Columns to Add

Create these three key columns next to each supplier's record in your spreadsheet. Rate each category on a scale of 1-5 (where 5 is excellent).

Column Name Rating Scale What to Measure
Reliability Score 1 to 5 On-time delivery, order accuracy, consistency in meeting deadlines and specs.
Communication Score 1 to 5 Response speed, clarity, proactivity in updating issues, language proficiency.
QC Performance Score 1 to 5 Quality of received goods, defect rate, compliance with quality standards.
Overall Rating (Calculated) Average Automated average of the three scores for an objective overall rank.

Step-by-Step Implementation

  1. Expand Your Spreadsheet:Reliability, Communication, QC_Performance, and Overall_Rating.
  2. Define Your Criteria:
  3. Input Scores After Each Order:
  4. Calculate the Overall Rating:=AVERAGE(B2:D2) // Assuming scores are in columns B, C, D
  5. Sort and Rank:Overall_Rating
