Running the register and the other channel by hand
The register and the TikTok Shop listing are the same unit of stock. When only one of them knows it sold, the other keeps offering it. That is how you oversell.
| 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 Square and TikTok Shop 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 either shop reaches the other in under a second |
One TikTok Shop order, start to finish
Real timings, second by second.
TikTok Shop · order #447114:02:11TikTok Shop41sourceSquare41+0.3sCorrecting Square takes under a second once we have the sale. The order is in your packing list with the TikTok Shop order number on it, and a tracking number added later goes back to TikTok Shop on its own.
The other direction is the same: a sale on Square reaches TikTok Shop just as quickly, because Square pushes it to us the moment it happens too.
Connecting Square and TikTok Shop takes about ten minutes
Most of that is us matching your catalogues. The two connections themselves are a login each.
Connect Square
You sign in to Square and approve QuickSync. It covers your catalogue, stock and orders across the locations you pick.
Connect TikTok Shop
You approve QuickSync in TikTok Shop Seller Center for the shop you want connected.
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 Square TikTok Shop integration has constraints. These are the ones that apply here.
Quick between Square and TikTok Shop
Both Square and TikTok Shop tell us the moment something sells, so a sale in one is reflected in the other in under a second. There is no polling gap on this pair.
No tracking number back to Square
Square has no field for us to write a tracking number into, so shipping detail lives in QuickSync and in whichever shop the order came from. Counter sales rarely need it; posted ones are worth knowing about.
Nothing publishes itself to Square or TikTok Shop
Copying a listing from Square 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.
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.

$19/mo for two shops1,000 items and up to eight connected integrations, with stock matched on both sides automatically. Enough for Square and TikTok Shop on their own, at $19 a month for the two.

Questions people ask about this pair
How quickly does TikTok Shop update after something sells on Square?
Under a second in normal conditions. Square tells us the moment the sale happens and we write the new count to TikTok Shop straight away. The reverse is the same when TikTok Shop sells. If either side is briefly unreachable we hold the update and keep trying rather than dropping it.
Do I have to re-list my Square products on TikTok Shop?
No. We match your existing Square 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 Square and TikTok Shop to the same number.
Does the tracking number go back to both shops?
Not to Square. Square has no way for us to send a tracking number back, so the shipping detail stays in QuickSync and in whichever shop the order came from.
Does a TikTok Shop order get recreated on Square?
No. The order stays on TikTok Shop. We pull it into your one QuickSync list next to your Square orders so you pack from one place, without creating a duplicate Square order for it.
What happens if a buyer cancels or I refund them on Square 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 Square and TikTok Shop.
Which plan do I need for Square and TikTok Shop?
Lite covers Square 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.
