Squarespace QuickBooks integration that keeps your books in step with your stock
For Squarespace shops that keep their books in QuickBooks. Squarespace tells us about an order the moment it is placed, so the invoice is written from the sale itself rather than from a nightly export. Stock stays right on the shop, and the books match the shelves without anybody typing it twice.

QuickBooksHow to connect Squarespace and QuickBooks
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 Squarespace
You generate an API key in Squarespace and paste it into QuickSync.
Connect QuickBooks
You sign in to Intuit and pick the company file. QuickSync writes to that company and nothing else.
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 Squarespace alone versus with QuickBooks
Every Squarespace sale that is not written into QuickBooks is a stock figure and an invoice someone has to type twice, and a wrong stock figure is how you oversell. Connecting them removes that second pass.
| 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 Squarespace and QuickBooks 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 reaches QuickBooks as an invoice in about a second |
One Squarespace order, start to finish
Real timings, second by second.
Squarespace · order #447114:02:11Squarespace41sourceQuickBooks41+0.3sCorrecting QuickBooks takes under a second 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.
There is no other direction: nothing is ever bought in QuickBooks, so it only ever receives.
The limits: know them before you connect
Every Squarespace QuickBooks integration has constraints. These are the ones that apply here.
One direction only
A Squarespace sale becomes an invoice in QuickBooks in about a second. Nothing is ever bought in QuickBooks, so there is no second direction to wait on.
QuickBooks is your books, not a shop
Quantities in QuickBooks are a bookkeeping figure no shopper ever sees, and orders go in as invoices without coming back out. That is by design, not a gap.
Stock moves when you say so
QuickBooks is not a storefront, so there is no listing to publish. Stock and invoices move once you turn sync on; nothing invents a product page on Squarespace.
Orders arrive at once, stock corrections wait
Squarespace announces a sale straight away. A quantity you edit yourself waits for the next check.
Squarespace splits how it reports, and the split shows up in your books. An order is announced the moment it is placed, so the invoice for it is written promptly. A quantity you change by hand inside Squarespace is not announced at all, so finding it falls to a check that comes round every couple of minutes. Same shop, two speeds, and it is the second one you plan around.
The bookkeeping consequence is worth spelling out. Revenue in the company file keeps pace with your Squarespace sales, because those come to us as they happen. The quantity on hand is the figure that can trail: write off a damaged item or finish a stocktake in Squarespace, and the books hold the old number for a minute or two. If you run a stock report the instant you finish counting, run it again after the next check.
The rest of what we write is standard across every shop connected to a company file: an invoice with a line per product matched on SKU, further lines for whatever the sale added on top, and the item quantity kept in step. Tax needs one caveat. Outside Canada we send the lines non-taxable, so QuickBooks does not levy it a second time on an amount Squarespace has already taken, while Canadian files use the code you set up. Payouts and card fees are not ours to post.
The SKU has to fit inside sixty characters
Squarespace is the tighter side, and matching is what the whole connection rests on.
Items pair on their SKU, so the shorter allowance is the one that governs. QuickBooks will store 100 characters; Squarespace stops at 60. A longer code reaches Squarespace trimmed to fit, and a trimmed code no longer names the product it came from. Nothing goes red when this happens, which is why it usually turns up weeks afterwards as a count that has quietly stopped moving. Sort by SKU length before you connect, not after.
Two more things belong here. Orders travel inwards only: QuickBooks accepts invoices and hands nothing back, so nothing you do in the company file will produce a Squarespace order or a Squarespace product page. And there is nowhere in QuickBooks to record a tracking number, so anything you generate for a parcel stays in QuickSync. Neither is a gap we are working on; both are how the accounting side is built.
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.

Questions people ask about this pair
How quickly does QuickBooks update after something sells on Squarespace?
Under a second in normal conditions. Squarespace tells us the moment the sale happens, and the invoice and the stock figure are written to QuickBooks straight away. Nothing is ever bought in QuickBooks itself, so there is no sale there for us to go looking for. If QuickBooks is briefly unreachable we hold the update and keep trying rather than dropping it.
Does QuickSync sync Squarespace inventory to QuickBooks?
Yes. Each Squarespace order is written into the company file as an invoice, and the quantity on hand for the matching item is kept up to date. Items pair on their SKU, which has to fit inside 60 characters because Squarespace stops there. Nothing travels back the other way, since QuickBooks does not release orders to anyone.
How quickly does a Squarespace change reach QuickBooks?
It depends which change. An order is announced by Squarespace as it is placed, so it reaches us straight away and the invoice follows. A quantity you edit yourself in Squarespace is not announced, so we look for it every couple of minutes. In practice sales are prompt and your own stock corrections take a moment longer.
Do my Squarespace products show up as listings in QuickBooks?
No. QuickBooks is your books, not a storefront, so there is nothing to list. We write the item and the quantity as a bookkeeping figure, and orders arrive as invoices.
Do prices sync from Squarespace to QuickBooks?
One way, yes. The price you set on Squarespace is written to the matching item in QuickBooks, so the books read what you actually charge. QuickBooks never writes a price back, so that number stays yours to set on Squarespace.
Does the tracking number go back to Squarespace?
Yes, to Squarespace. When you add a tracking number to an order we send it back and the buyer gets the shop’s normal notification. QuickBooks holds the invoice rather than the buyer, so there is nobody there to notify.
Do orders flow both ways with QuickBooks?
No. A Squarespace sale becomes an invoice in QuickBooks. Nothing is imported back out of QuickBooks into your shops; it is a one-way accounting sink by design.
What happens if I refund a Squarespace order?
The stock goes back on Squarespace and the quantity on the books updates with it. Handle the invoice credit in QuickBooks the way you normally would; we keep the quantity right, not your accountant’s credit-note workflow.
Which plan do I need for Squarespace and QuickBooks?
Lite covers Squarespace and QuickBooks. 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.
