Connect your own SKU to the eBay item ID
Create the internal SKU and storage bin before the listing goes live. After publishing, paste the eBay item ID into the same row. That two-key system lets you find the physical item by SKU while still matching payouts, returns, and listing edits to eBay records.
Do not reuse a SKU for a replacement item. If a returned item is relisted, keep the original SKU only when it is the same physical unit and record the new item ID or relist date in notes.
- Label the item or poly bag with the exact SKU shown in the sheet.
- Keep listing status and physical location in separate columns.
- Record multi-quantity inventory as a quantity only when the units have the same cost basis.
