Step 1: Define Your Data Structure
Create dedicated columns for each pillar. For example:
| Vendor Name | QC Score (1-10) | Accuracy Score (1-10) | Comm Score (1-10) | Overall Rating | Notes |
|---|---|---|---|---|---|
| Vendor A | 9 | 8 | 10 | 9.0 | Excellent responsiveness |

Leverage Custom Scoring for QC, Accuracy, and Communication to Identify Your Top Vendors
In the world of sourcing, your spreadsheet is more than a data log—it's your command center. For BBDBuy users and sourcing professionals, a static list of vendors falls short. Transforming it with a dynamic Seller Ranking System

- Operational Accuracy:
- Communication & Responsiveness:
- Operational Accuracy:
Step-by-Step: Building the System in Your Spreadsheet
Step 2: Establish a Custom Scoring Logic
Not all pillars are equally weighted. Assign a percentage weight based on your priorities. For instance:
- QC Score: 50%
- Accuracy Score: 30%
- Communication Score: 20%
- Accuracy Score: 30%
In your Overall Rating=(QC*0.5)+(Accuracy*0.3)+(Communication*0.2)
Step 3: Implement Continuous Data Entry & Review
After each order or quarterly review, update the scores. Consistency is key. Use a separate "Transaction Log" tab to record specific incidents that justify score changes, ensuring your rankings are objective and evidence-based.
Step 4: Visualize with Conditional Formatting
Use color scales on the Overall Rating
