Reviewing the Customer Complaint and Non-Conformance Review screen from February–May 2026, the overall picture is relatively positive, with very few issues that would currently justify a formal CAPA or QC21 escalation.

Key Observations
1. Majority of Issues are Administrative Errors

Most entries relate to:

Shopify fulfilment not completed
Memo omissions
Address/account selection errors
Stock communication errors
VAT/Incoterms mistakes
Dispatch date misunderstandings

In nearly all cases:

The error was identified quickly.
Immediate correction was made.
The issue was closed as "Done".
No recurring systemic cause was identified.
2. No Significant Customer Complaint Trend

The monthly Non-Conformance Review reports completed by Helen found:

No new customer complaint trends.
No increase in feedback requiring investigation.
No significant increase in order-entry errors.
No unresolved corrective actions.
3. Product-Related Issues Being Monitored Appropriately

The notable product-related reviews are:
