Square QuickBooks integration that keeps your books in step with your stock
For shops that ring sales through a Square register and keep the books in QuickBooks. Every counter sale becomes an invoice on the day it happens, rather than a report someone keys in on Monday. Stock stays right on the shop, and the books match the shelves without anybody typing it twice.

| Orders in | Into QuickSync | Invoices go in, nothing comes back |
| Tracking back | Square does not accept one | Not applicable |

Running Square alone versus with QuickBooks
Every Square 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 Square 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 Square order, start to finish
Real timings, second by second.
Square · order #447114:02:11Square41sourceQuickBooks41+0.3sCorrecting QuickBooks takes under a second once we have the sale. The order is in your packing list with the Square order number on it.
There is no other direction: nothing is ever bought in QuickBooks, so it only ever receives.
Connecting Square and QuickBooks 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 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.
The limits: know them before you connect
Every Square QuickBooks integration has constraints. These are the ones that apply here.
One direction only
A Square 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 Square.
Intuit's own connector already does the money
It is free, it is good at settlements, and it is not what we are for.
Search this and you land on Square Connector by QuickBooks, made by Intuit, which pulls your Square sales, refunds, card fees, taxes, tips and payouts into the company file and matches them to the deposits that reach your bank. It does that job well and it costs nothing. If reconciling your takings is the problem you have, stop here and use it.
What it is not built to do is keep a stock count straight across the places you sell. It is reading Square to write your books, and it treats the catalogue as something to map transactions onto rather than something to correct. That is the right design for an accounting bridge, and it leaves the inventory question untouched.
QuickSync writes each sale into QuickBooks as an invoice and sets the quantity on hand for the item, and it does the same from every other shop you connect. The two tools do not collide, because they write different things into different places. Plenty of merchants run the Intuit connector for the money and us for the stock.
Locations decide which stock the books describe
Square counts per location. Your company file holds one number per item.
When you connect Square you choose which locations QuickSync covers, and that choice is the one that decides what your QuickBooks quantity actually means. A merchant with a shop, a stall and a stockroom has three counts in Square and one item in the company file, so the figure we set is the total of the locations you handed us rather than any single till’s view.
Worth settling before you connect rather than after, because it changes how the number reads at year end. If a location is deliberately left out, its stock is invisible to the books and that is a decision rather than a fault. If it is left out by accident, the books quietly understate what you own.
The sale itself lands as an invoice in that same company file, with product lines matched to QuickBooks items by SKU and a separate line for anything else the receipt carried. Tax is the part to check first: outside Canada we mark the lines non-taxable so QuickBooks does not add tax again on top of what Square already collected.
Nothing comes back out of the company file
Invoices go in. No listing, no order and no tracking comes the other way.
QuickBooks does not hand orders back out, so no invoice will ever become a Square sale. There is nothing to publish there either: no listing to build, no photo to upload and no variant to map, because the company file is your bookkeeping rather than a place a customer can buy from. The quantity we set against an item is a figure for your reporting and your accountant.
Tracking has nowhere to go on either side of this pair, which is unusual. Square has no field for us to write a number into, and QuickBooks has no buyer waiting to be told. If you post orders taken at the register, the tracking stays visible in QuickSync and nowhere else in this pairing.
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 Square and QuickBooks 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 QuickBooks update after something sells on Square?
Under a second in normal conditions. Square 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 Square integrate well with QuickBooks?
For bookkeeping, yes. Intuit’s own Square Connector is free and brings sales, refunds, fees, taxes and payouts into the company file. The gap it leaves is inventory: it is not built to keep one stock count straight across a till and the other places you sell. That is the part QuickSync does, and the two run alongside each other without conflict.
What are the common problems between QuickBooks and Square?
The two that come up most are double-counted tax and a catalogue that never quite lines up. We handle the first by marking invoice lines non-taxable outside Canada so QuickBooks does not recalculate tax on top of the amount Square already collected. The second is a SKU problem: items match by SKU, so anything without one, or with a different one on each side, will not pair up.
Does QuickSync post Square payouts and card fees to QuickBooks?
No. We write the sale, not the settlement, so the deposit that reaches your bank and the fees Square deducted from it are not something we post. Intuit’s Square Connector does that job and can run at the same time as us, because it writes summaries and deposits while we write invoices and stock.
Do my Square 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 Square to QuickBooks?
One way, yes. The price you set on Square 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 Square.
Does the tracking number go back to Square?
No. 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. QuickBooks holds the invoice rather than the buyer, so there is nobody there to notify either.
Do orders flow both ways with QuickBooks?
No. A Square 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 Square order?
The stock goes back on Square 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 Square and QuickBooks?
Lite covers Square 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.
