Download a list of the SKUs your platform listings use that are not yet in your OneCart inventory, from Manage Listings > View All Imported Listings > Reports > Missing SKUs, then add them manually or by bulk upload.
The Missing SKUs report lists every SKU that appears on your imported platform listings but does not yet exist in your OneCart inventory. Until those SKUs exist in OneCart, the listings that use them cannot be matched, so their stock and orders are not synced.
Use this report after importing listings from a new shop, or whenever the Imports page shows listings waiting to be matched.
A SKU is on the list when both of these are true:
SKUs that already exist in OneCart are left out, even if the listing is still unmatched. Each SKU appears once, even if several listings use it.
The file downloads straight away, named OneCart-MissingSKUs-<your company>-<date>. The first two rows are notes explaining the list; the SKUs follow, one per row.
Tip: pick the Excel version if any of your SKUs start with zeros. The Excel file stores SKUs as text, so 00123 stays 00123. Opening the CSV in a spreadsheet can strip the leading zeros.
The same Reports menu also offers the Jumbolist (CSV) and Jumbolist (Excel) exports, which list all your imported listings. Those are different reports; for missing SKUs use the two Missing SKUs options.
Once you have the list, create the SKUs in your inventory so the listings can be matched:
After the SKUs exist, return to the Imports page and match the listings. See Matching your platform listings in OneCart.
What happens if I leave SKUs missing? The listings that use them stay unmatched, so OneCart cannot update their stock or pull their orders into your inventory counts.
Can I regenerate the list after updating? Yes. Open Reports and download it again. It always reflects your current inventory.
The report is empty. Is that right? It means every SKU on your unmatched imports already exists in OneCart. If listings are still unmatched, match them from the Imports page.
