Square integration that syncs stock, listings and orders

Connect Square and everywhere else you sell reads from the same number. Sell on Square and the others drop to match. Sell somewhere else and Square drops to match. You keep one count instead of five.

What syncs

What a Square integration actually moves

One row per job. Where Square does not allow something, the row says so plainly, with no tick that carries fine print.

Checked against how QuickSync connects to Square, not against Square’s marketing.
The jobDoes it?What that means
Stock we send outYesWe set the exact number on Square instead of nudging it up and down, which is what keeps two tools from overwriting each other.
Stock we read inYesWe can ask Square for a product’s current number whenever something looks wrong, as well as taking the changes it reports.
ListingsCreate and updateWe can put a product on Square with its photos, options, description and category, then keep that listing in step with your other shops afterwards.
PricesSentSelling price and the was-price both go across. You pick the direction, and a rule can add a margin so Square is not stuck at another shop’s price.
Orders coming inYesSquare orders land in one list with the customer, the address, the shipping and the right product attached. An order still awaiting payment waits until it is paid.
Orders going outYesSquare can be the shop that fills orders taken somewhere else. Seven of the thirteen integrations can take an order in like this, and Square is one of them.
Tracking going backNot acceptedSquare has no field for us to write a tracking number into. It is one of four integrations that will not accept one, so the shipping detail stays in QuickSync and in whichever shop the order came from.
How fast we update itUnder a secondWe write new numbers to Square immediately. The outbound half is fast on all thirteen integrations.
How fast it tells usThe moment it happensSquare pushes us a message as it happens instead of making us check on a timer. Four of the thirteen only allow the timer, which is why they run a little behind.
Connecting

How the Square connection is made

About two minutes, no developer, and nothing to copy or paste anywhere.

What you click

You sign in to Square and approve QuickSync. It covers your catalogue, stock and orders across the locations you pick.

What we ask for

Your products and stock, and your orders. Payment card details are never part of it. We ask for what the jobs in the table above need and nothing beyond that.

How you disconnect

From QuickSync’s settings, or from Square’s own screen for the apps it is connected to. Either side is enough on its own. Your Square products, stock and orders stay exactly where they are.

In the app

What your Square products look like once connected

Products, Orders and Settings is the whole of it. There is no dashboard to learn.

Every product keeps one number of its own, and each shop it is connected to shows what that shop currently says. When the two disagree you can see it on the same row, along with when it was last put right.

Orders from Square arrive in the same list as orders from everywhere else, already matched to the right product.

  • One count per product, with each shop’s number beside it
  • Anything we cannot match goes to a short review list, and we never guess
  • Safety stock per shop, so the last one or two are never exposed everywhere at once

Limits

Square limits: know them before you connect

Every sync tool has constraints. These are the ones that apply here.

Square tells us as it happens

Square pushes us a message the moment a count moves or an order lands, so there is no polling delay on this one.

No tracking number back to Square

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.

Nothing publishes itself

Copying a listing onto Square always waits for you to look at it. Stock is the only thing that moves on its own, and only once you have turned that direction on.

Getting started

Connecting Square takes about ten minutes end to end

Most of it is you reviewing the product matching, not waiting on us. A Square integration only starts changing things when you tell it to.

Connect Square

You sign in to Square and approve QuickSync. It covers your catalogue, stock and orders across the locations you pick.

~2 minutes

Connect the other shop

The same again for wherever else you sell. Square on its own has nothing to stay in step with, so you need at least two connected before anything happens.

~2 minutes

Let it match your products

We line the catalogues up by SKU first, then by title, and hand you a short list of whatever we could not match. You decide what happens to those.

~5 minutes

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 and one direction at a time if you prefer.

A day, or a week
Combinations

Connect Square with

Each combination has its own guide, because no two channels allow exactly the same things.

Or read about another shop on its own

Every integration has a page covering what it can and cannot do.

Pricing

Square is inside the smallest plan

Order volume never changes your bill. Your catalogue size picks the plan, and your plan price covers two connected shops with every shop after that adding it again.

Lite

$19/mo for two shops

1,000 items and up to eight connected integrations, with stock kept in step. Square counts as one of the eight, so there is room for seven more.

Pro

$29/mo for two shops

2,500 items and up to eight connected integrations, and the point at which listings and orders start syncing as well as stock. Most sellers running a second shop 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.

FAQ

Questions Square sellers ask

How quickly does QuickSync know about a Square sale?

Straight away. Square tells us the moment an order is placed or a count changes, so we are never sitting on a timer waiting to check. In normal conditions the other shops you sell in are corrected inside a second or two. If Square has an outage, we hold the change and retry until it goes through.

What does QuickSync get access to on Square?

Your products and stock, and your orders, and nothing beyond what the jobs in the table above need. Payment card details are never part of what we receive. You can withdraw the access from the Square side whenever you like, and we stop.

Will connecting Square change my listings?

No. Nothing on Square is edited, published or unpublished until you turn a direction on, and copying a listing onto Square always waits for you to look at it first. Most sellers leave it watching for a few days and check the numbers agree before letting it make any changes.

Can orders from my other shops be sent into Square?

Yes. Square is one of the integrations that can take orders in as well as hand them out, so you can run it as the shop that fills everything. The order arrives with its customer, address and line items, matched to the right Square product where the SKU lines up.

Does the tracking number go back to Square?

No. Square has no field for us to write one into. Square, Clover and Amazon are the three shops that will not accept a tracking number, so on those you still add it on the shop’s own screen. The rest send it back on their own, except Lightspeed, which marks the order shipped but keeps no number against it.

Which plan do I need for a Square integration?

Lite covers Square, at $19 a month for two shops with every shop after that adding another $19, and 1,000 items with stock kept in step. Pro at $29 adds listings and orders and 2,500 items. Eight shops is the limit on every plan. Every plan starts with a 14-day free trial and no card.

Connect Square and watch one shop correct the other

Make one test sale and watch the other shop’s count drop. If it does not work the way this page describes, you have spent ten minutes and no money.
