Changing a Multi-Variant Listing to a Single-Variant Listing (and Vice Versa)

On eBay, you cannot directly convert a listing from a single-variant to a multi-variant listing, or from a multi-variant listing to a single-variant listing. This is a limitation of eBay’s platform, not Omnivore.


The same rules apply to most other marketplaces as well.


  • You cannot add variations/options if the product is listed already
  • You cannot remove variations/options if the product is listed already
  • You cannot rename variations/options if the product is listed already
  • On eBay, trying to change a product structure will likely result in an eBay validation error, such as "Invalid Multi-SKU item id supplied with variations."


Why This Happens

  • eBay treats single-variant listings and multi-variant listings differently in their system.

  • Each type of listing has its own structure for SKUs, variation specifics (such as size or colour), and inventory tracking.

  • Attempting to change the listing type directly will result in errors or listing failures.


How to Change Listing Type Correctly

To change a listing from single to multi-variant or vice versa, you must:

  1. End the existing listing on eBay.

  2. Delete the old product on your website

  3. Create a new listing on your website with the correct type:

    • Standalone product for individual products.

    • Multi-variant listing if the product has multiple options (e.g., sizes, colours).

  4. Re-upload the new listing via Omnivore/eBay LINK.
