Amazon Squarespace integration that keeps one stock count
For sellers with a Squarespace shop who also list on Amazon. Both sides share one stock count so a sale in either place corrects the other. Both shops tell us the moment something sells, so the other is corrected in a second or two. Stock you edit yourself inside Squarespace is the slower path: we pick that up every couple of minutes.

SquarespaceWhat a Amazon Squarespace integration actually moves
One row per job, based on how QuickSync connects to Amazon and Squarespace today. Where a side does not allow something, the cell says so.

|---|---|---|
| Stock count | We always send, and hear back for items you ship | Both ways |
| 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 | Amazon does not accept one from us | Sent to the order |
| Photos and options | Photos, sizes and colours | Photos, sizes and colours |
| How fast we update it | A second or two | Under a second |

Running Amazon and Squarespace by hand
Nearly every problem selling on both Amazon and Squarespace 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 Amazon and Squarespace 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 a second or two |
One Squarespace order, start to finish
Real timings, second by second.
Squarespace · order #447114:02:11Squarespace41sourceAmazon41+1.4sCorrecting Amazon takes a second or two once we have the sale. The order is in your packing list with the Squarespace order number on it, and a tracking number added later goes back to Squarespace on its own.
The other direction is the same: a sale on Amazon reaches Squarespace just as quickly, because Amazon pushes it to us the moment it happens too.
Connecting Amazon and Squarespace takes about ten minutes
Most of that is us matching your catalogues. The two connections themselves are a login each.
Connect Amazon
You authorise QuickSync in Seller Central for the marketplaces you sell in.
Connect Squarespace
You generate an API key in Squarespace and paste it into QuickSync.
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 Amazon Squarespace integration has constraints. These are the ones that apply here.
Sales are instant; stock edits wait
A sale on either side reaches the other in a second or two. Stock you edit yourself inside Squarespace is the slower path: we check that every couple of minutes.
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 Amazon or Squarespace
Copying a listing from Amazon to Squarespace (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 matched on both sides automatically. Enough for Amazon and Squarespace 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 Squarespace update after something sells on Amazon?
A second or two in normal conditions. Amazon tells us the moment the sale happens and we write the new count to Squarespace straight away. The reverse is the same when Squarespace 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 Amazon products on Squarespace?
No. We match your existing Amazon and Squarespace 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 Squarespace?
Yes. Set a rule once for Squarespace: a percentage, a fixed uplift, or a price you type yourself. We apply it whenever the price changes, and nothing forces Amazon and Squarespace 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 Squarespace from a sale on Amazon?
No. Amazon and Squarespace 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 Amazon or Squarespace?
The stock goes back. A cancellation or a refund puts the item back into your count and we send the corrected number to both Amazon and Squarespace.
Which plan do I need for Amazon and Squarespace?
Lite covers Amazon and Squarespace. 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.
