Leveraging data visualization to track supplier reliability and shipping efficiency.
For dropshippers and e-commerce entrepreneurs using PinguBuy, maintaining profitability hinges on supplier performance. A well-structured spreadsheet, paired with dynamic charts, transforms raw data into actionable insights. This guide will walk you through analyzing three key metrics: Refund Ratios, Quality Control (QC) Pass Rates, and Average Shipping Costs
1. Structuring Your Performance Spreadsheet
Start with a table that logs data consistently (e.g., weekly or monthly).
| Period (Week/Month) | Total Orders | Refunded Orders | QC Inspections Passed | QC Inspections Failed | Total Shipping Cost |
|---|---|---|---|---|---|
| 2024-W05 | 150 | 12 | 138 | 5 | $845.50 |
| 2024-W06 | 165 | 8 | 160 | 2 | $912.75 |
From this base, you can calculate our three core performance indicators per period:
- Refund Ratio (%)
- QC Pass Rate (%)
- Avg. Shipping Cost ($)
- QC Pass Rate (%)
2. Creating Insightful Charts
Visualize the calculated metrics using a line or combo chart. Most spreadsheet tools (like Google Sheets or Excel) have built-in charting features.
Chart 1: Refund Ratio & QC Pass Rate Trend (Dual-Axis Line Chart)
This chart reveals the correlation between quality and refunds.

Chart 2: Average Shipping Cost Over Time (Line Chart)
This tracks logistics cost efficiency.
