eBay TikTok Shop integration that keeps one stock count across both marketplaces
For sellers listing the same stock on eBay and TikTok Shop. Both cap a SKU at 50 characters and both take a tracking number back, so one product code and one dispatch routine cover the pair. TikTok Shop 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.

One eBay sale, and how fast it reaches the other shop
Real timings, including the wait. A sale on TikTok Shop is the quicker direction, because TikTok Shop tells us and eBay does not.
eBay · order #447114:02:11eBay41sold hereTikTok Shop41+0.3sCorrecting TikTok Shop 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 TikTok Shop reaches eBay in a second or two, because TikTok Shop pushes it to us the moment it happens.
What to know before you connect
Every eBay TikTok Shop integration has constraints. These are the ones that apply here.
eBay waits; TikTok Shop does not
A TikTok Shop sale reaches eBay in a second or two. An eBay sale reaches TikTok Shop 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.
Listings do not publish to eBay or TikTok Shop on their own
Copying a listing from eBay to TikTok Shop (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.
Neither one can fulfil the other's orders
Two marketplaces, and no fulfilment relationship between them. That is their rule, not a gap in ours.
People connecting a shop to a marketplace often expect the marketplace to ship for them. This pair is two marketplaces, so there is nothing to arrange in that direction. eBay cannot be told to fulfil a TikTok Shop order, and TikTok Shop cannot be told to fulfil an eBay one. Neither platform offers it to the other, which means picking and posting stays with you whichever side the sale came from.
What is left is the part that matters anyway: one stock figure across both. Items match by SKU, and a sale on either marketplace lowers the other, so you are not trying to keep two sets of listings honest by hand. That is the whole job on this pair, and it is worth being clear that it is the whole job rather than implying more.
Being two marketplaces has one practical consequence beyond fulfilment. Neither side is the natural home for your catalogue, so decisions about naming and structure belong in the middle rather than on the platform you happen to prefer. If you have been treating one of them as the master copy and the other as a mirror, this is the point to stop doing that.
eBay does not announce a sale, so we ask
Stock and orders both come off a check every couple of minutes on the eBay side.
eBay does not tell us when something sells. We check it every couple of minutes for both stock and orders, which is fine for most catalogues and worth knowing on anything that moves quickly. If the last unit of a fast line is live on both marketplaces, there is a short window where each still shows it as available. A small buffer on those lines is the usual fix.
SKU length is not the constraint here that it is elsewhere. Both platforms take 50 characters, so eBay’s limit is the one quoted and the two sides are level. Fifty is comfortable for most naming schemes, but the truncation behaviour is the same as everywhere: a longer SKU gets shortened on the way out and then stops matching, with no error to point at it.
So the check before you connect is short. Confirm nothing runs past 50 characters, then accept that fulfilment is yours on both sides and that eBay-side changes arrive on a timer. There is no third surprise waiting on this pair, which is not something we can say about every combination we support. It is a genuinely simple pair to run.

Questions people ask about this pair
How quickly does TikTok Shop 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 TikTok Shop takes under a second. The other direction is much quicker: TikTok Shop 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 eBay and TikTok Shop?
Yes. Items match by SKU and a sale on one marketplace lowers stock on the other. Both platforms take 50 characters of SKU, so length is rarely the problem here. eBay does not announce sales to us, so its stock and orders are checked every couple of minutes rather than arriving instantly.
Can TikTok Shop or eBay fulfil each other’s orders?
No. Both are marketplaces, and neither offers fulfilment to the other, so you pick and post every order yourself whichever side it came from. That is a limit of the two platforms rather than something a sync tool can add. What we keep in step is the stock figure across both.
Do I have to re-list my eBay products on TikTok Shop?
No. We match your existing eBay and TikTok Shop 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 TikTok Shop?
Yes. Set a rule once for TikTok Shop: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces eBay and TikTok Shop 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 eBay or TikTok Shop the order came from, and the buyer gets the shop’s normal notification.
Can I create an order on TikTok Shop from a sale on eBay?
No. eBay and TikTok Shop 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 TikTok Shop?
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 TikTok Shop.
Which plan do I need for eBay and TikTok Shop?
Lite covers eBay and TikTok Shop. 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.
