This article covers common eBay stock and price sync errors and how to fix them.
First, make sure your eBay listings use Good 'Til Cancelled and the out-of-stock option is on. Without it, eBay can end a listing when SKULabs pushes a quantity of zero. See eBay Good Til Cancelled / Allow out-of-stock options.
"FixedPrice item ended. You are not allowed to revise an ended item."
eBay does not allow stock or price updates on an ended fixed price listing. Relist the item on eBay, then run a listings sync in SKULabs so stock sync uses the new listing. See How to run listings sync for your stores.
"SKU Mismatch. SKU does not exist in Non-ManageBySKU item specified by ItemID"
The SKU in SKULabs no longer matches the SKU on the eBay listing, usually because the SKU was changed on eBay. SKULabs retries these updates using the eBay item ID. If the error keeps appearing, run a listings sync so SKULabs picks up the current SKU.
"Category is not valid. This category is not valid Select another category."
eBay changed or retired the category the listing uses. Edit the listing on eBay, choose a valid category and save. The next stock push will succeed.
"Cannot revise a Multi-SKU item when item level SKU is supplied"
The listing-level Custom label (SKU) on eBay is the same as one of its variation SKUs. On eBay, edit the listing and change or remove the listing-level Custom label (SKU) so it does not match any variation SKU. Save, then run a listings sync in SKULabs. For screenshots, see Cannot revise an eBay Multi-SKU item when item level SKU is supplied.
