Pro Tips for Effective Auditing

Track Trends, Not Snapshots

Compare quarterly reports. A vendor's declining performance trend is often more telling than a single bad month.

Cross-Reference Data

Does a vendor with high refunds also have QC failures? This pattern confirms a deep-seated quality problem.

Consider Order Volume

A 50% refund rate on 2 orders is less alarming than 20% on 100 orders. Weight your analysis by volume.

Document & Communicate

Use your spreadsheet to create a clear audit summary. Share findings with the vendor to initiate corrective action.

Conclusion

CNFANS spreadsheet reports are your first line of defense against supply chain instability. By systematically auditing refund frequency, QC failures, and delayed shipments, you can objectively identify high-risk vendors, allocate your resources wisely, and build a more resilient and reliable supplier network. Turn data into insight, and insight into action.
