Managing multiple suppliers can be challenging. A structured, objective rating system within your MyCNBox spreadsheet transforms subjective impressions into clear, actionable data. Here's a step-by-step guide to building your own supplier ranking dashboard.
Why Implement a Seller Rating System?
Without a formal system, supplier evaluations often rely on memory or recent—sometimes atypical—experiences. A built-in rating system in your procurement spreadsheet helps you:
- Make Objective Decisions:
- Identify Top Performers:
- Pinpoint Improvement Areas:
- Save Time & Reduce Risk:
- Identify Top Performers:
Step 1: Add the Core Scoring Columns
In your main supplier or order tracking spreadsheet, add three dedicated columns next to each supplier's or order's record. These will form the backbone of your evaluation:
| Column Name | Scoring Scale (1-5) | Key Evaluation Criteria |
|---|---|---|
| Reliability Score | 1 (Poor) to 5 (Excellent) | On-time delivery, adherence to quoted lead times, fulfillment accuracy (correct items/quantities). |
| Communication Score | 1 (Poor) to 5 (Excellent) | Response speed, clarity, proactivity in updating issues, professionalism, language fluency. |
| QC Performance Score | 1 (Poor) to 5 (Excellent) | Product quality vs. sample, defect rate, packaging appropriateness, compliance with specifications. |
Consider adding a Comments
Step 2: Establish Consistent Scoring Guidelines
Consistency is key. Define what each number means for your business. For example:
- 5 (Excellent):
- 4 (Good):
- 3 (Average):
- 2 (Below Average):
- 1 (Poor):
- 4 (Good):
Tip: Score each order or interaction shortly after completion, while details are fresh.
Step 3: Calculate the Overall Supplier Rank
Create a Supplier Summary Sheet
Example Formula for Overall Score (using Google Sheets or Excel syntax): This formula averages the three category scores for each supplier to generate a final Overall Score. You can also apply weighting if one category (e.g., QC) is more critical for you:
=IFERROR(
(AVERAGEIF(Orders!$B$2:$B$100, SupplierName, Orders!$C$2:$C$100) + // Avg Reliability
AVERAGEIF(Orders!$B$2:$B$100, SupplierName, Orders!$D$2:$D$100) + // Avg Communication
AVERAGEIF(Orders!$B$2:$B$100, SupplierName, Orders!$E$2:$E$100) // Avg QC
) / 3,
"N/A"
)
(Reliability*0.3 + Communication*0.2 + QC*0.5).
Step 4: Visualize and Use Your Data
Turn your data into an at-a-glance dashboard:
- Create a Ranking List:
- Use Conditional Formatting:
- Generate Charts:
- Use Conditional Formatting:
Use this system to award more business to top-ranked suppliers, have data-driven improvement talks with underperformers, and make informed decisions when sourcing new products.
Conclusion: Data-Driven Sourcing Decisions
Integrating a simple but structured seller rating system into your MyCNBox spreadsheet empowers you to manage your supply chain proactively. By consistently tracking reliability, communication, and QC performance, you build a valuable historical database that reduces uncertainty, saves time in the long run, and ultimately contributes to a more resilient and profitable import business.
