WooCommerce eBay integration that keeps one stock count
For WooCommerce shops that also list on eBay. Both sides accept a tracking number back from us, which is not true of every pair here, so a parcel you post against an order in either place shows the same courier reference in the other. That is the difference between one dispatch routine and two. WooCommerce tells us the moment something sells, so eBay is corrected in a second or two. eBay does not announce a sale, so we check it every couple of minutes instead.

eBayWhat a WooCommerce eBay integration actually moves
One row per job, based on how QuickSync connects to WooCommerce and eBay today. Where a side does not allow something, the cell says so.
| What | WooCommerce | eBay |
|---|---|---|
| Stock count | Both ways | Both ways |
| New listings | We can create and update | We can create and update |
| Prices | Sent, with your rule applied | Sent, with your rule applied |
| Orders in | Into QuickSync | Into QuickSync |
| Tracking back | Sent to the order | Sent to the order |
| Photos and options | Photos, sizes and colours | Photos, sizes and colours |
| How fast we update it | Under a second | A second or two |

Running WooCommerce and eBay by hand
Nearly every problem selling on both WooCommerce and eBay comes from each side keeping its own count. Sell the last one twice and you oversell somebody.
| Two shops, run by hand | Two shops, connected |
|---|---|
| The last one sells in both shops within the same hour | Whichever shop sells it, the other one drops to match |
| Typing the same stock numbers into WooCommerce and eBay each morning | One count, sent to both, without anyone opening a spreadsheet |
| Changing a price means editing the same product twice | Change it once and each shop gets the price you set for it |
| Orders in two dashboards, matched up by hand at the end of the week | Every order already matched to the right product |
| A refund leaves your numbers wrong until someone notices | A refund puts the stock back and tells both shops |
| Guessing how stale each shop’s number is | A sale on eBay is found within two minutes and WooCommerce is corrected straight after |
One eBay order, start to finish
Real timings, including the wait. A sale on WooCommerce is the quicker direction, because WooCommerce tells us and eBay does not.
eBay · order #447114:02:11eBay41sourceWooCommerce41+0.3sCorrecting WooCommerce takes under a second once we have the sale. The order is in your packing list with the eBay order number on it, and a tracking number added later goes back to eBay on its own.
The other direction is faster: a sale on WooCommerce reaches eBay in a second or two, because WooCommerce pushes it to us the moment it happens.
Connecting WooCommerce and eBay takes about ten minutes
Most of that is us matching your catalogues. The two connections themselves are a login each.
Connect WooCommerce
You install the QuickSync plugin on your WordPress site and paste a key. Nothing on your shop changes until you turn a sync on.
Connect eBay
You sign in to eBay and grant QuickSync access to the selling account.
Let it match your products
We line the two catalogues up by SKU, then by title, and hand you a short list of anything we could not match. You decide what happens to those.
Watch, then switch it on
Leave it watching for a few days and check the numbers agree. When you are happy, let it start making changes, one shop at a time.
The limits: know them before you connect
Every WooCommerce eBay integration has constraints. These are the ones that apply here.
eBay waits; WooCommerce does not
A WooCommerce sale reaches eBay in a second or two. An eBay sale reaches WooCommerce on our next look, which is within two minutes. Hold back a little safety stock and that window stops mattering.
eBay is checked, not pushed
eBay does not announce sales to us, so we look every couple of minutes. A little safety stock on your fastest sellers covers that window.
Nothing publishes itself to WooCommerce or eBay
Copying a listing from WooCommerce to eBay (or the other way) always waits for you to look at it. Stock is the only thing that moves on its own, and only once you have turned it on.
WooCommerce holds 300 characters, eBay takes 50
Six times the room on one side, and the shorter limit is the one that governs.
Items pair up by SKU, so the shorter of the two limits decides what your naming scheme can be. WooCommerce will store a SKU up to 300 characters, which is more room than any catalogue needs. eBay takes 50. Anything longer is truncated on the way to eBay, and a truncated SKU no longer matches the item it came from, so the count for that item stops moving.
Nothing errors when this happens, which is why it catches people out. We send the shortened SKU rather than refusing the item, so no listing turns red and no warning appears anywhere. The item simply stops pairing with itself, and you find out weeks later when the eBay count and the WooCommerce count disagree by a few units and nobody can say when they parted.
Fifty characters is enough for a sensible code and not enough for a sentence. If your WooCommerce SKUs were generated from product titles, that is where the trouble will be, because nobody ever had a reason to shorten them. Export your catalogue, order it by SKU length, and deal with the top of the list in one pass before you connect anything.
eBay never tells us it sold something
We ask, every couple of minutes, and that shapes what you can expect.
Some channels announce a sale the moment it happens. eBay is not one of them: it has no way of telling us anything, for stock or for orders, so we check it on a timer every couple of minutes and pick up whatever changed since the last look. WooCommerce is the opposite and announces its own changes straight away, so this pair is live in one direction and checked in the other.
In practice the window is small and it is not zero. If the same item sells on eBay and on your WooCommerce site inside the same minute, the eBay sale is waiting to be noticed while the website still believes the stock is on the shelf. A unit or two of safety stock on your fastest movers covers that gap, and planning around it beats assuming it away.
Two shops fits the smallest plan
Your catalogue size picks the plan, and your plan price covers two connected shops with every shop after that adding it again. Three shops on Lite is $38 a month.
Lite
$19/mo for two shops1,000 items and up to eight connected integrations, with stock matched on both sides automatically. Enough for WooCommerce and eBay on their own, at $19 a month for the two.
Pro
$29/mo for two shops2,500 items and up to eight connected integrations. Listings and orders sync here as well as stock. Most sellers running two shops properly end up here.
Ultra at $69 and Ultra+ at $99 add larger catalogues, price rules and setup help. Every plan starts with a 14-day free trial and no card.
Questions people ask about this pair
How quickly does WooCommerce update after something sells on eBay?
Within two minutes. eBay has no way of telling us the moment a sale happens, so we check it on a short timer instead. Once we have the sale, correcting WooCommerce takes under a second. The other direction is much quicker: WooCommerce tells us straight away. If either shop has an outage, we hold the update and retry until it goes through.
Can I sync inventory between WooCommerce and eBay?
Yes. Neither platform reads the other’s catalogue, so it takes a third-party tool. QuickSync matches items by SKU and holds one count between them, so an eBay sale lowers your WooCommerce stock and a web order lowers what eBay shows. Keep SKUs to 50 characters or fewer, which is eBay’s limit and the tighter of the two.
How quickly does eBay stock update from WooCommerce?
WooCommerce tells us about a change as soon as it happens, so it leaves for eBay right away. Coming back the other way is slower: eBay does not announce anything, so we check it every couple of minutes for both stock and orders. Plan for a couple of minutes on the eBay side rather than seconds.
Do I have to re-list my WooCommerce products on eBay?
No. We match your existing WooCommerce and eBay listings by SKU first, then by title, and hand you a short list of whatever we could not match. You can also copy a listing from one side to the other if you want it in both places; that step always waits for you.
Can I charge a different price on eBay?
Yes. Set a rule once for eBay: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces WooCommerce and eBay to the same number.
Does the tracking number go back to both shops?
Yes. When you add a tracking number to an order, we send it back to whichever of WooCommerce or eBay the order came from, and the buyer gets the shop’s normal notification.
Does an eBay order get recreated on WooCommerce?
No. The order stays on eBay. We pull it into your one QuickSync list next to your WooCommerce orders so you pack from one place, without creating a duplicate WooCommerce order for it.
What happens if a buyer cancels or I refund them on WooCommerce or eBay?
The stock goes back. A cancellation or a refund puts the item back into your count and we send the corrected number to both WooCommerce and eBay.
Which plan do I need for WooCommerce and eBay?
Lite covers WooCommerce and eBay. Lite is $19 a month for two shops and holds 1,000 items, with up to eight connected integrations. You would move up a plan for catalogue size, and your bill goes up by another $19 if you connect a third shop.
