Square Clover integration that keeps one stock count
For businesses running a Square register in one place and a Clover register in another. Neither accepts a tracking number back, which suits a counter, and the shorter SKU of the two — Square’s 80 characters — is the one both have to fit. Both sides tell us the moment something sells, so the other is corrected in under a second.

CloverHow to connect Square and Clover
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 Square
You sign in to Square and approve QuickSync. It covers your catalogue, stock and orders across the locations you pick.
Connect Clover
You install QuickSync from the Clover app market on the merchant account that owns the register.
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.

Running Square and Clover by hand
Nearly every problem selling on both Square and Clover 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 Square and Clover 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 Clover order, start to finish
Real timings, second by second.
Clover · order #447114:02:11Clover41sourceSquare41+0.3sCorrecting Square takes under a second once we have the sale. The order is in your packing list with the Clover order number on it.
The other direction is the same: a sale on Square reaches Clover just as quickly, because Square pushes it to us the moment it happens too.
The limits: know them before you connect
Every Square Clover integration has constraints. These are the ones that apply here.
Quick between Square and Clover
Both Square and Clover 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 Clover
Copying a listing from Square to Clover (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 register is the master
Two point-of-sale systems, no website in the middle, and no natural owner of the number.
This is the pair where both sides are counters. There is no storefront acting as the obvious source of truth, so the question is not which platform to trust but where the count should live. QuickSync holds it between them and corrects each side from the other, which means a sale on the Square register lowers what Clover will let you sell, and a Clover sale does the same to Square.
Shops end up here for ordinary reasons. A second site opened with different hardware, a business bought with its till already in place, a market stall running Square while the shop runs Clover. In each case the stock is one pool and the two systems have no idea the other exists. Left alone they part company within a weekend, and you find out with a customer waiting.
Both sides announce their changes to us as they happen, so nothing here is on a timer. That matters most when the same item can sell in two rooms in the same minute, which is precisely the situation two tills create. A count that moves as each sale is rung through is the difference between telling the second customer no and selling them something you do not have.
Neither till will take a tracking number
Square has no field for one and neither does Clover, so it stays in QuickSync.
This is the gap to know about before you start posting orders taken over the counter. Square has no field for a tracking number and neither does Clover, so there is nowhere for us to write one on either side. The number stays visible in QuickSync, which on this pair is the only place that holds it, and that is a limit of the two platforms rather than a step we skipped.
For most till sales it is irrelevant, because the customer leaves with the item in a bag. It matters when someone orders at the counter for delivery later, or when a member of staff works out of one register and expects the shipping detail to sit on the sale. Point them at QuickSync, and settle that habit early rather than during a week when parcels are going out.
The other number to know is SKU length. Items pair up by SKU, and Square is the shorter side at 80 characters against Clover’s 100. Eighty is roomy for a till code, so most shops never come near it, but anything over the line is truncated on the way to Square and then stops lining up with the item it belongs to. One look at your longest codes is enough.

Questions people ask about this pair
How quickly does Clover 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 Clover straight away. The reverse is the same when Clover sells. If either side is briefly unreachable we hold the update and keep trying rather than dropping it.
Can Square and Clover share the same inventory?
Yes, with a tool in the middle, because neither reads the other’s catalogue. QuickSync matches items by SKU and holds one count across both tills, correcting each side from the other. Both report their changes to us immediately, so nothing sits on a timer. Keep SKUs within 80 characters, which is Square’s limit.
Which system is the master when Square and Clover are synced?
Neither. There is no storefront in this pair to act as an obvious source of truth, so QuickSync holds the count between the two and corrects each till from the other. A sale on Square lowers what Clover will sell and a sale on Clover lowers Square, without either one owning the figure.
Do I have to re-list my Square products on Clover?
No. We match your existing Square and Clover 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 Clover?
Yes. Set a rule once for Clover: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces Square and Clover to the same number.
Does the tracking number go back to both shops?
Not to Square and Clover. 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. Clover has no way for us to send a tracking number back. Counter sales rarely need one, but it is worth knowing if you also ship from the same stock.
What happens if a buyer cancels or I refund them on Square or Clover?
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 Clover.
Which plan do I need for Square and Clover?
Lite covers Square and Clover. 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.
