eBay Amazon integration that keeps one stock count across both marketplaces
For sellers listing the same stock on eBay and Amazon. One warehouse count, two marketplace storefronts. Amazon 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.

AmazonWhat a eBay Amazon integration actually moves
One row per job, checked against how QuickSync connects to eBay and Amazon, not against either platform’s marketing. Where a side will not let us do something, the cell says so.
| What | eBay | Amazon |
|---|---|---|
| Stock count | Both ways | We always send, and hear back for items you ship |
| 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 your one list | Into your one list |
| Tracking back | Sent to the order | Amazon does not accept one from us |
| Photos and options | Photos, sizes and colours | Photos, sizes and colours |
| How fast we update it | A second or two | A second or two |
| How fast it tells us | We check every two minutes | The moment it happens |
Running two marketplaces from one warehouse by hand
Two marketplaces with two counts is how you oversell the same SKU in one afternoon. One warehouse number behind eBay and Amazon is the fix.
| 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 eBay and Amazon 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 in one list, 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 Amazon is corrected straight after |
Somebody buys on eBay. Here is what happens next.
The honest version, including the wait. A sale on Amazon is the quicker direction, because Amazon tells us and eBay does not.
eBay · order #447114:02:11eBay41sourceAmazon41+1.4sCorrecting Amazon takes a second or two 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 Amazon reaches eBay in a second or two, because Amazon pushes it to us the moment it happens.
Connecting eBay and Amazon takes about ten minutes
Most of that is us matching your catalogues. The two connections themselves are a login each.
Connect eBay
You sign in to eBay and grant QuickSync access to the selling account.
Connect Amazon
You authorise QuickSync in Seller Central for the marketplaces you sell in.
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 to expect, including the awkward bits
Every eBay Amazon integration has constraints it would rather you found later. These are ours.
eBay waits; Amazon does not
An Amazon sale reaches eBay in a second or two. An eBay sale reaches Amazon on our next look, which is within two minutes. Hold back a little safety stock and that window stops mattering.
Stock Amazon holds is left alone
We always send your count to Amazon, but we only take changes back for items you ship yourself. Anything Amazon stores and ships keeps its own count, which is Amazon’s to own.
Nothing publishes itself to eBay or Amazon
Copying a listing from eBay to Amazon (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.
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 kept in step automatically. Enough for eBay and Amazon on their own, at $19 a month for the two.
Pro
$29/mo for two shops2,500 items and up to eight connected integrations, and this is where listings and orders start syncing 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 Amazon 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 Amazon takes a second or two. The other direction is much quicker: Amazon tells us straight away. If either shop is having a bad day we hold the update and keep trying until it goes through.
Do I have to re-list my eBay products on Amazon?
No. We match your existing eBay and Amazon 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 Amazon?
Yes. Set a rule once for Amazon: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces eBay and Amazon to the same number.
Does the tracking number go back to both shops?
Not to Amazon. Amazon has no way for us to send a tracking number back.
Can I create an order on Amazon from a sale on eBay?
No. eBay and Amazon hand orders out and do not accept orders created elsewhere. We pull both into one packing list so you still work from one place; each order stays on the channel it came from.
What happens if a buyer cancels or I refund them on eBay or Amazon?
The stock goes back. A cancellation or a refund puts the item back into your count and we send the corrected number to both eBay and Amazon.
Which plan do I need for eBay and Amazon?
Lite covers eBay and Amazon. 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.
