How Dealership Inventory Feeds Work
A complete guide to dealership inventory feeds — how they work, the major Canadian platforms, and what separates a great vehicle listing from a wasted one.
Key takeaways
- Inventory feeds push vehicle data from a dealership's DMS to listing platforms automatically
- Major Canadian platforms include AutoTrader.ca, Cars Commerce, HomeNet, and Kijiji Autos
- Feed quality affects how well vehicles rank and convert on listing platforms
- Stale or incomplete feeds cost real sales — feed health is an operational priority
Quick Answer
A dealership inventory feed is the automated data flow that pushes vehicle inventory from a dealership's DMS to third-party listing platforms — AutoTrader.ca, Cars Commerce, Kijiji Autos, HomeNet, and the dealership's own website. Without feeds, every vehicle would have to be manually listed on every platform every time it's added, updated, or sold. Feed quality directly affects how vehicles rank in search results, how often customers view them, and how many leads they generate.
What is a dealership inventory feed?
A dealership's inventory exists in many places at once. The vehicles are physically on the lot, the records are in the DMS, the listings are on the dealership website, and the same listings are also on AutoTrader.ca, Kijiji Autos, the manufacturer's website, and any other third-party listing platforms the dealership pays to be on. All of these representations need to stay in sync — when a vehicle sells, every listing should disappear within minutes; when prices change, every listing should update.
Inventory feeds make this happen automatically. The DMS (or an inventory feed provider sitting on top of it) generates a structured data file or API stream containing every vehicle in inventory and the relevant data — VIN, year/make/model, mileage, condition, photos, pricing, status, location, options. That feed is delivered to each listing platform, which uses it to update its own database.
Without inventory feeds, dealerships would be stuck doing what they did 20 years ago: manually creating each listing on each platform, manually updating prices when they change, manually marking vehicles sold across multiple sites. With feeds, a single update in the DMS propagates to every platform within minutes.
The major Canadian inventory listing platforms
Most Canadian dealerships push their inventory to multiple platforms at once. The major options:
AutoTrader.ca
The dominant Canadian automotive marketplace. Most franchise and independent dealerships list inventory here, and customers shopping for vehicles online almost always start with AutoTrader. Listing quality directly affects search ranking and lead generation.
Kijiji Autos
Owned by eBay until 2025 and now part of Kijiji Canada's automotive vertical. Strong presence with consumers, particularly for used and lower-priced vehicles. Many dealerships use both AutoTrader and Kijiji Autos in parallel.
Cars Commerce
An umbrella platform that includes inventory feed services and dealer marketing tools. Less consumer-facing than AutoTrader but important for dealership operations.
HomeNet
An inventory management and feed distribution platform owned by AutoTrader Group. HomeNet manages the dealership's master inventory record and pushes feeds to multiple downstream platforms simultaneously.
D2C Media
A Canadian dealership digital marketing platform that includes inventory listing and dealer website services. Particularly strong with multi-rooftop dealer groups.
OEM Manufacturer Sites
Most major OEMs (Honda, Toyota, Ford, GM, etc.) require franchise dealerships to maintain inventory listings on the manufacturer's national website, with specific feed formats and refresh requirements.
How inventory feeds technically work
The data structure
Most inventory feeds use either an XML-based structured file format (FTP-delivered nightly or hourly) or a real-time API (webhook or polling). Each vehicle in the feed contains a standard set of fields:
- VIN — the unique identifier
- Year / Make / Model / Trim
- Mileage / Odometer reading
- Condition — new, used, certified pre-owned
- Pricing — list price, internet price, MSRP, special offers
- Photos — multiple high-resolution images
- Vehicle description — features, options, condition notes
- Stock number and location
- Status — available, pending, sold
Refresh frequency
Feed refresh frequency varies by platform and dealership tier. Older batch feeds update once or twice per day. Modern API-based feeds update in near-real-time, with most major platforms refreshing within 15 minutes of a change in the DMS. The faster the refresh, the less risk of selling a vehicle that's still listed elsewhere or showing a stale price.
Photo handling
Photos are often the most operationally complex part of inventory feeds. They have to be high quality, properly tagged, in the right order, and pushed to each platform's specific image hosting requirements. Many dealerships use a third-party photo management service (such as HomeNet Photos) that handles the photo workflow separately from the rest of the feed.

Why feed quality matters
Most dealerships think of inventory feeds as a technical plumbing concern. They aren't. Feed quality directly affects how often customers see your vehicles, how those vehicles rank against the competition, and how many leads each listing generates. The dealerships with the best feed quality consistently outsell competitors with similar inventory and pricing.
Search ranking on listing platforms
AutoTrader, Kijiji Autos, and other platforms rank vehicles in search results using their own algorithms — and feed completeness is one of the major inputs. Vehicles with full data, multiple high-quality photos, complete option lists, and accurate pricing rank higher than vehicles with partial or incorrect data. Higher rankings mean more views, which means more leads.
Customer trust
Stale data — wrong price, wrong photos, vehicle marked as available when it's actually sold — destroys customer trust. A customer who finds out a listed vehicle isn't actually available is unlikely to come back to the dealership for the next vehicle they consider.
Wasted advertising spend
Most listing platforms charge dealerships per vehicle per month. A dealership pushing junk data to AutoTrader is paying full listing fees for vehicles that don't generate leads — effectively burning money.
Time-to-frontline integration
The faster a vehicle moves from "frontline ready" in the DMS to "live on AutoTrader," the sooner it can generate leads. Dealerships with fast, automatic feed updates see vehicles start generating leads within minutes of being marked ready in the DMS. Dealerships with slow batch feeds wait hours or even a full day. See the Days to Frontline pillar for how this connects to overall used-car velocity.
Common feed quality issues
1. Missing photos
Vehicles listed without photos, or with only one or two photos, get dramatically fewer views than vehicles with a full photo set (typically 20-40 images). Yet missing photos remain one of the most common feed quality issues across the industry.
2. Sold vehicles still showing as available
The DMS is updated, but the feed didn't refresh, so the vehicle is still listed on AutoTrader for days after it sold. Customers contact the dealership about a vehicle that doesn't exist. Bad experience all around.
3. Wrong pricing
The dealership updates pricing in the DMS but the feed lags. Customers see one price online and a different price when they arrive. Trust violations and embarrassed sales staff.
4. Incomplete option lists
The vehicle has heated seats, navigation, and a sunroof, but the feed only mentions "automatic transmission." Searches that filter for those features won't find the vehicle. Lost leads.
5. Bad condition descriptions
Generic descriptions ("clean used vehicle") instead of specific condition notes. Customers can't tell what they're looking at and self-select away from the listing.
6. Stale data from old DMS records
Vehicles that were marked "in process" weeks ago and never updated, vehicles in the wrong location, vehicles still showing the original acquisition condition rather than the current reconditioned state.
Frequently asked questions
What is an inventory feed?
An inventory feed is the automated data flow that pushes vehicle inventory from a dealership's DMS to third-party listing platforms like AutoTrader.ca, Kijiji Autos, and HomeNet. Without feeds, every vehicle would have to be manually listed and updated on every platform separately.
How often do inventory feeds update?
Modern API-based feeds update within 15 minutes of a change in the DMS. Older batch feeds update once or twice per day. The faster the refresh, the less risk of stale data on listing platforms.
What's the difference between HomeNet and AutoTrader?
AutoTrader.ca is a consumer-facing marketplace where shoppers search for vehicles. HomeNet is an inventory management and feed distribution platform — owned by AutoTrader Group — that helps dealerships manage their inventory data and push it to multiple listing platforms simultaneously. Most dealerships use AutoTrader as a listing platform and may also use HomeNet to manage the data flow.
How do photos get into inventory feeds?
Photos are typically uploaded to a photo management service (such as HomeNet Photos) that handles hosting, ordering, and distribution. The feed itself contains URLs to the hosted photos rather than the photo files themselves. Photo workflow is often the most operationally complex part of inventory listing.
Why does feed quality affect search ranking?
Listing platforms rank search results using their own algorithms, and feed completeness is a major input. Vehicles with full data, multiple high-quality photos, complete option lists, and accurate pricing rank higher than vehicles with partial or incorrect data. Higher rankings mean more views and more leads.
Does READY HUB push to inventory feeds?
READY HUB Inventory tracks vehicles through the reconditioning workflow and marks them frontline-ready. The actual feed distribution to listing platforms happens through your DMS or a dedicated feed provider — but READY HUB ensures the "ready" status flows back to the DMS the moment a vehicle is actually ready to list, so the feed update happens fast.
The bottom line
Inventory feeds are the connective tissue between a dealership's DMS and the marketplaces where customers actually shop. Most dealerships treat feeds as plumbing — set them up once and ignore them. The dealerships that treat feed quality as an operational priority consistently outsell their competitors at the same inventory level, because their vehicles rank higher, look better, and convert more visitors into leads.
The fastest improvement available to most dealerships isn't more inventory or more advertising — it's making sure the inventory they already have shows up cleanly and quickly on the platforms where customers are actually looking.
