Follow one Squarespace sale

For Squarespace shops that also list on Amazon. Amazon cuts a SKU at 20 characters against Squarespace’s 60, and it keeps its own count for anything held in FBA: your stock always goes out to Amazon, and only the items you ship yourself come back.

What to know before you connect

Inventory limit

FBA inventory stays with Amazon

We always send your count to Amazon, but we only take changes back for items you ship yourself. Anything Amazon stores and ships for you (FBA) keeps its own count, which is Amazon's to own.

Manual control

Listings do not publish to Amazon or Squarespace on their own

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.

Which way stock moves

FBA stock is Amazon’s to count, not ours

We always send your figure out. What comes back depends on who ships the item.

Every stock change we know about goes out to Amazon, so a Squarespace sale lowers what Amazon shows. The return trip is where the rule sits. Where you pack and post an item yourself, Amazon’s own adjustments come back to us and carry on to Squarespace. Where Amazon warehouses and ships it, we do not touch that figure. Which of your items are meant to agree depends entirely on that split.

The reason is that Amazon knows its own shelves. What happens inside those warehouses, from receipts to damages to returns, never comes past us, so writing our number over Amazon’s would be a guess dressed up as a sync. Leaving that count where it is means the items it covers are not supposed to match your Squarespace figure. A book number that quietly disagrees with a warehouse is worse than none.

Two things to check

Twenty characters, and a timer on one side

Amazon has the tightest SKU limit here; Squarespace has the one gap in reporting.

Squarespace will hold 60 characters of SKU. Amazon takes 20, which is the tightest limit we deal with anywhere. Since matching happens on the SKU, anything longer is truncated on the way to Amazon and then pairs with nothing. Codes built out of words reach twenty faster than you would think, so read your longest ones before you connect rather than after a count has drifted.

The timing gap is on the Squarespace side and it is narrow. Squarespace tells us about orders as they happen, but not about a quantity you edit yourself, so we check for that every couple of minutes. If you adjust a number in Squarespace and expect Amazon to know within seconds, that is the one case on this pair where you will be waiting.

Tracking is the last thing to plan for. Amazon offers nowhere to record a tracking number, so the number the carrier gives you lives in QuickSync and not on the Amazon order. That only affects you if somebody on your team reads tracking off the sale in Amazon itself, and if they do, it is far better they hear it now than in week three.

Questions people ask about this pair

How do I connect Amazon to Squarespace?

You authorise QuickSync in Seller Central for the marketplaces you sell in. You generate an API key in Squarespace and paste it into QuickSync. Then match products by SKU, choose which shop holds the true count on day one and turn the sync on. Keep SKUs within 20 characters, Amazon’s limit.

Can I sync Amazon inventory with a Squarespace store?

Yes, matched by SKU, with two caveats. Amazon truncates any SKU longer than 20 characters, so design to that. And stock that Amazon holds and ships keeps its own count deliberately, so those items are not meant to follow your Squarespace figure. Items you ship yourself sync in both directions.

Does QuickSync send tracking numbers to Amazon?

No. There is no field on Amazon that holds a tracking number, so we have nowhere to put one and it stays visible in QuickSync. If your team works out of Amazon and is used to reading tracking off the sale, that is the habit to change before you connect rather than after the first parcel goes out.

Do I have to re-list my Amazon products on Squarespace?

No. We match your existing Amazon and Squarespace listings by SKU, 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?

A refund alone does not restock an item. When the originating platform reports a stock increase, QuickSync propagates the updated quantity between 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.
