Choosing the right supplier is critical for success in cross-border e-commerce. The USFANS methodology empowers buyers to make data-driven decisions by systematically tracking supplier performance. This guide explains how to leverage a dedicated spreadsheet to evaluate seller reliability.

1. The Core Metrics: What to Track

Your USFANS spreadsheet should be built around three fundamental pillars of supplier reliability:

  • QC Success Rate:
  • Order Delays:
  • Feedback History:

2. Structuring Your Spreadsheet

Create separate sheets or tables for clear data organization:

Supplier ID/Name QC Pass Rate (%) Avg. Delay (Days) Feedback Score (1-5) Total Orders Notes & Incidents
Supplier_A 95 +2 4.7 50 Excellent communication, minor packaging issues twice.
Supplier_B 82 -1 (Early) 4.0 30 Sometimes slow to respond, but consistently delivers early.

3. Analyzing the Data for Trustworthiness

Interpret QC Rates:

A rate above 90%

Understand Order Delays:

Consistency is key. A supplier with a consistent +3 day

Decode Feedback History:
