Keeping your website inventory and your Marketplace listings in sync
August 23, 2026
Getting the lot onto Marketplace is a one-time job. Keeping it accurate is the job that never ends, and it is the one that quietly decides whether Marketplace is worth doing at all.
What drift actually looks like
Nobody sets out to run stale listings. It happens in a predictable order.
Week one, everything matches. You listed forty cars and all forty are right.
Week two, the first price moves. A unit has been sitting, so it comes down eight hundred dollars. Your website updates because your inventory system feeds it. Marketplace does not, because Marketplace only knows what somebody typed into it a fortnight ago.
Week three, something sells. The listing stays up. Now you are getting messages about a car that is gone, and every one of those costs a salesperson three minutes and a small amount of goodwill.
Week five, new stock arrives and does not get listed. Not because anybody decided not to, but because the person who did the first batch has a day job and forty new listings is an afternoon nobody has.
By week eight the Marketplace presence is a museum of what the lot looked like in month one. The listings that are still accurate are accurate by accident.
Why doing it by hand does not hold
The arithmetic is against you. A hundred-car lot with normal turn might see a dozen price changes and eight or ten units in and out in a month. That is roughly twenty edits a month, spread unevenly, each one small enough to postpone and none of them urgent enough to schedule.
Work that is individually trivial and collectively enormous is exactly the work that does not get done. The problem is not that anybody is lazy. It is that there is no moment in a normal week when updating a two-week-old Marketplace price is the most important thing on the desk.
Fixing it at the source
The way out is to stop treating Marketplace as a place you maintain, and start treating it as a reflection of something you already maintain.
You already keep inventory accurate somewhere. It feeds your website, because your website has to be right or your leads dry up. That system is the source of truth, and everything else should follow it rather than being kept in step by hand.
So the loop becomes: your inventory changes, your website reflects it, and your listings follow your website. Price drops in one place. Sold gets marked in one place. New stock gets added in one place. Nobody updates the same car twice.
What that looks like day to day
Once a morning, the whole picture is pulled together: what your website says the lot is now, and what is currently live on Marketplace. Then the differences are the work.
- A price that moved on your site gets pushed to the listing.
- A unit marked sold gets its listing taken down.
- Something new on your site gets written up and queued.
- Anything on Marketplace that no longer lines up with a vehicle gets flagged so you can link it or clear it.
That last one matters more than it sounds. Listings get orphaned. Somebody posted a car manually months ago, or a listing was edited by hand until it no longer matches the record it came from. Those need a human to look at them once, and then they stay linked.
Two things worth knowing
Once a day is the right frequency. Not because more often is technically hard, but because reading your live Marketplace listings is activity on your Facebook account, and doing it hourly is a burst of account activity that returns nothing. Your inventory does not change between ten and eleven in the morning.
Which platform your site runs on matters. Inventory pages are structured differently by every website vendor. DealerOn, Leadbox and Dealer e-Process are handled directly, and a good number of others are read by a general-purpose reader that understands how dealer sites lay out a vehicle. It is worth checking your own inventory URL before assuming either way.
The part that actually pays
When the listings are current, Marketplace stops being a channel you feel guilty about and becomes one you can quote numbers on. Prices are right, so the enquiries are about cars you have at prices you are asking. Sold units are down, so nobody is calling about the RAV4 that left on Tuesday. New arrivals are listed while they are still new arrivals, which is when they get looked at.
None of that is glamorous. It is just the difference between a channel that works and a channel that is technically switched on.
