# How Do I Connect Customer Complaints to Supplier-Caused Defects?

You connect complaints to supplier-caused defects by tracing a reported issue backward through the batch to the raw material lot and its supplier, using existing traceability data. On **Jestor**, this runs through complaint records connected to traceability data.

A customer complaint investigated without connecting backward through the supply chain misses the opportunity to identify and hold the actually responsible supplier accountable.

## What disconnected complaint-to-supplier tracing costs

- Missed opportunity to identify the supplier actually responsible for a defect
- No systematic way to confirm whether a complaint traces back to a specific material
- Difficulty building a case to hold a supplier accountable without clear traceability
- Risk of absorbing cost for an issue that was genuinely the supplier's responsibility

## How connecting complaints to supplier-caused defects works

- A reported issue traces backward through the **batch** to its raw material lot
- The lot connects further back to the **supplier** who provided that material
- This traceability confirms whether a complaint genuinely stems from a supplier issue
- A documented trace supports holding the responsible supplier accountable

## Why Jestor fits this use case

- Backward traceability identifies the genuinely responsible party, not a guess
- This supports a documented, defensible case for supplier accountability
- Cost that genuinely belongs to a supplier gets attributed correctly
- This scales from occasional complaints to a high-volume quality operation
