Yes. In the supplier portal, open Listings. Under Listing details for each listing, you see how your price compares to the best price on Ordentic for that product variant.
The best price is the lowest listing price for the same product among sellable and comparison listings. Shipping is not part of that comparison. If you have the best price, you see that you have the best price. If a lower price exists, you see the best price on Ordentic. If your listing is inactive and would win, you see that you would have the best price if your listing was active.
