-
Step 4: Separate SKU and barcode
An internal stock code and a barcode can serve different purposes.
On-screen labels: Internal stock code; Barcode identifier; Different purposes.

Step 5: Use the code in the workflow

-
Step 6: Check changes carefully
Review affected records when an item or its code changes.
On-screen labels: Updated record; Staff understanding; Consistent reference.
A practical check for your business

- Specific item: The product or variant
- Internal code: A distinct stock reference
