Start from an available vehicle and a channel such as Facebook, Craigslist, OfferUp, Instagram, or your dealer website.
Prepare the listing. You post it.
Create a listing draft from inventory and keep the public URL after you post it. Direct publishing to outside marketplaces is not connected.
Edit the title and body, then post through your own marketplace account.
Paste the public listing URL back into DealerOS so the post is on record.
Sold or unavailable vehicles are flagged for removal. DealerOS does not publish or take the listing down for you.
