Transforming raw supplier data into actionable insights using dynamic charts.
The Critical Need for Vendor Analysis
In today's complex supply chains, choosing the right vendor is more than a procurement decision—it's a strategic imperative. Relying on gut feeling or single metrics like price can lead to costly disruptions, quality failures, and reputational damage. At RizzitGo, we advocate for a data-driven approach, leveraging the power of spreadsheet visualization
By systematically tracking and visualizing three core pillars—QC Pass Rates, Refund Frequency, and Feedback Ratings—you can move from guesswork to guided decision-making.
The Three Pillars of Vendor Reliability
1. Quality Control (QC) Pass Rate
The percentage of shipped units that meet all specified quality standards upon inspection. A high, consistent pass rate indicates robust manufacturing processes and effective internal QC.

2. Refund Frequency
The rate at which customer complaints lead to refunds or replacements. This is a direct indicator of end-customer satisfaction and the true cost
3. Feedback Ratings
Aggregate scores from internal procurement teams or end-users. This subjective metric captures intangible factors like communication, problem-solving, and professionalism.

Building Your Dynamic Comparison Dashboard
Here’s how to transform a simple spreadsheet into an interactive vendor analysis tool using charting features available in Excel, Google Sheets, or data visualization tools.
Step 1: Data Structuring
Organize your data in a clean table. Each row should represent a vendor, and columns should include the three core metrics over time (e.g., monthly).
Vendor | Month | QC_Pass_Rate (%) | Refunds_per_1000 | Avg_Rating
-------|-------|------------------|------------------|-----------
Vendor A | Oct | 99.2 | 2.1 | 4.7
Vendor A | Nov | 98.5 | 3.4 | 4.5
Vendor B | Oct | 97.0 | 5.6 | 4.0
Vendor B | Nov | 96.8 | 6.7 | 3.8Step 2: Creating Dynamic Charts
Chart A: Combo Chart for Holistic View
- Use:
- Insight:
Chart B: Scatter Plot for Correlation Analysis
- Use:
- Insight:
Chart C: Trend Lines for Time-Series Analysis
- Use:

Step 3: Making it Interactive
Use drop-down menus (Data Validation) to select a vendor and have all charts update automatically. Add slicers or filters to view data for specific time periods. This turns a static report into a living dashboard.
RizzitGo in Action: A Hypothetical Analysis
Imagine analyzing three electronics vendors. The dashboard reveals:
| Vendor | QC Pass Trend | Refund Trend | Rating Trend | Visualization Insight | Verdict |
|---|---|---|---|---|---|
| AlphaTech | Steady at 99% | Low & Stable | High & Stable | All lines are flat and in the "green zone" across all charts. | High Reliability |
| BetaGadgets | Volatile (92% - 98%) | High & Peaking | Declining | Scatter plot shows a tight negative correlation: low QC points coincide with high refund points. | High Risk |
| GammaParts | Steady but low (96%) | Moderate | Moderate | Consistently in the middle of all charts. No major red flags, but no excellence. | Secondary/Backup |
