2026-02-20

Effectively managing a sourcing business requires data-driven decisions. For PinguBuy users, a well-structured spreadsheet is a powerful tool to track and analyze key performance indicators (KPIs) like refund rates, Quality Control (QC) pass rates, and shipping costs. This guide walks you through setting up charts to visualize these metrics over time.

1. Structuring Your Data

First, organize your raw data in a table with consistent monthly (or weekly) entries. Essential columns should include:

2024-02 165 5 90 85 1380.00

Calculation Columns:

  • Refund Ratio:
  • QC Pass Rate:
  • Avg. Shipping Cost per Order:

  • 2. Creating Insightful Charts
