SKU and barcode cleanup: one product at a time

Start small
- Choose one familiar product or a small batch.
- Save the original stock and listing exports before making changes.
- Keep SKU and barcode columns as text, including leading zeros.

Follow the product
- Record each Channel, listing ID, current SKU and barcode in the review CSV.
- Check variant, condition, pack size and stock pool before combining records.
- A shared title or barcode alone does not establish that two records should merge.

Agree the next step
- Note the reference SKU and any barcode correction supported by product evidence.
- Leave uncertain proposed codes blank and record the question to resolve.
- Add a name and next action; if you work alone, that can be you.
- Preserve old codes in your notes so earlier records remain traceable.

Apply a small reviewed change
- The supplied CSV is a review worksheet, not a direct ChannelWeave stock import.
- Use the receiving system's editing workflow or prepare its required import format.
- Validate and review a small batch before applying it.

Check and keep the result
- Confirm each affected listing points to the intended product and stock pool.
- Check existing orders and references still make sense.
- Verify the intended behaviour without an unplanned live stock change.
- Keep the original export, agreed changes and check result together.

Worksheet examples are illustrative. Use your own verified product identifiers.
