FishGoo: A Seller Performance Dashboard Using Spreadsheet Data Visualization

2025-12-17

Managing multiple vendors requires clear, actionable insights. Spreadsheet-based dashboards transform raw vendor data into a visual command center, enabling you to track critical metrics like refund rates, quality control, and delivery reliability efficiently.

1. Data Foundation: Structuring Your Raw Data

Consistent data entry is crucial. Maintain a master spreadsheet with the following columns per transaction or batch:

  • Vendor ID/Name
  • Order Date & Delivery Date
  • QC Pass/Fail Rate
  • Refund Status
  • Promised vs. Actual Delivery Days

2. Building the Performance Dashboard

Use pivot tables and charts in tools like Google Sheets or Excel to create a one-page summary.

Key Visualizations:

A. Refund Rate Trend Line Chart

Track the percentage of refunds per vendor over time. A rising trend signals product or listing issues.

Chart Tip: Use a separate line for each major vendor for quick comparison.

B. QC Results Bar or Gauge Chart

Visualize the monthly QC pass rate. A gauge chart can instantly show if a vendor is in the "green zone" (e.g., >98%).

C. Delivery Consistency Heat Map

Create a calendar-style heat map shading late deliveries (red) vs. on-time deliveries (green) per vendor. This highlights reliability patterns.

3. From Visualization to Action

The dashboard's power lies in driving decisions.

Metric Alert Potential Action
Refund rate spikes above 5% Initiate a product audit and discuss with the vendor.
QC rate drops below target Enforce stricter pre-shipment inspections for that vendor.
Consistent late deliveries Adjust lead time in listings or diversify suppliers.
