Wix eBay integration that keeps one stock count
Wix and eBay hold separate stock counts and neither updates the other, so a sync app is what puts one number behind both. For sellers with a Wix storefront who also move stock on eBay. Unusually, the website is the tighter side on codes: Wix keeps 40 characters of SKU against eBay’s 50. Wix 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.

eBayHow to connect Wix and eBay
Four steps and about ten minutes. The two connections are a login each; most of the time is us matching your catalogues, and nothing changes until you switch it on.
Connect Wix
You install QuickSync from the Wix App Market on your site and approve it. Billing runs through the Wix Apps marketplace.
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.
What a Wix eBay integration actually moves
One row per job, based on how QuickSync connects to Wix and eBay today. Where a side does not allow something, the cell says so.

| 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 |

Running Wix and eBay by hand
Nearly every problem selling on both Wix 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 Wix 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 Wix is corrected straight after |
One eBay order, start to finish
Real timings, including the wait. A sale on Wix is the quicker direction, because Wix tells us and eBay does not.
eBay · order #447114:02:11eBay41sourceWix41+1.4sCorrecting Wix takes a few seconds 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 Wix reaches eBay in a second or two, because Wix pushes it to us the moment it happens.
The limits: know them before you connect
Every Wix eBay integration has constraints. These are the ones that apply here.
eBay waits; Wix does not
A Wix sale reaches eBay in a second or two. An eBay sale reaches Wix on our next look, which is within two minutes. Hold back a little safety stock and that window stops mattering.
Wix mirrors the master store
Product edits made directly on Wix are overwritten on the next sync, by design: the master store is where the catalogue is edited, and Wix displays it. Stock and orders still move the moment they change, in both directions.
Nothing publishes itself to Wix or eBay
Copying a listing from Wix 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.
Wix announces; eBay is asked
One side pushes, the other is checked every two minutes.
Wix tells us the moment something sells, so an eBay listing drops to match within a few seconds of a website sale. eBay announces nothing to anyone; we check it every two minutes, and an eBay sale reaches Wix on the next check.
Two minutes only matters at speed. Hold one unit of safety stock on your genuinely fast sellers and the window stops being a risk; the rest of the catalogue never notices it.
Forty characters, and it's the website's limit
For once the marketplace isn’t the tight side.
On most eBay pairs the 50-character eBay SKU is the ceiling. Here Wix’s 40 is, so the shared code has to fit 40, and trimming long eBay custom labels before connecting makes the first match clean.
Product edits belong in the master store rather than on Wix, which mirrors the master and overwrites direct edits on the next sync. Tracking goes to both sides’ orders as normal.
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 Wix 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 Wix 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 Wix takes a few seconds. The other direction is much quicker: Wix 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 Wix and eBay?
Yes, with a sync tool between them. QuickSync matches by SKU (40 characters or fewer, Wix’s limit), corrects eBay within a few seconds of a Wix sale, and picks up eBay orders within two minutes of them being placed.
How fast does an eBay sale reach my Wix store?
Within two minutes: eBay doesn’t announce sales, so QuickSync checks it on a two-minute cycle. The other direction is faster, because Wix reports its sales the moment they happen.
Do I have to re-list my Wix products on eBay?
No. We match your existing Wix 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 Wix 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 Wix or eBay the order came from, and the buyer gets the shop’s normal notification.
Does an eBay order get recreated on Wix?
No. The order stays on eBay. We pull it into your one QuickSync list next to your Wix orders so you pack from one place, without creating a duplicate Wix order for it.
What happens if a buyer cancels or I refund them on Wix 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 Wix and eBay.
Which plan do I need for Wix and eBay?
Lite covers Wix 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.
