Shopify Square integration
Shopify Square Integration for Products, Inventory & Customers
The floor team keeps Square. The website stays on Shopify. The catalog, the count at each store, and the customer list stay in step.
Product sync
Products, either direction
Send products from Shopify to Square, or from Square to Shopify, including only the ones you select. You choose the direction. You do not have to move the whole catalog.
Fields
The fields that move are title, description, price, and image. Each variant’s SKU and price come along with the product.
How items link
Items link by a shared SKU, or by title when the SKU is missing. Clean obvious duplicates before the first sync so two similar names do not attach to the wrong item.
Already on the other side
Update products that are already linked, or create new ones on the other side. You do not start from an empty catalog if the item is already there.
Inventory sync
One count for each location pair
Inventory sync uses location pairs. Map a Shopify location to the Square location that holds the same stock, so each store shows the count for that place.
On-hand count
SquareFloww copies the on-hand count from your primary store to the paired location. The other store shows the same number.
What you select
Sync the stock you select. A busy Saturday does not force a full-catalog recount if only a few items changed.
With a product import
A product import or export can copy stock for those items too. You do not need a separate stock run for the products you just moved.
Customer sync
One profile, in the store and online
Sync customers from Shopify to Square, from Square to Shopify, or both. Name, email, and phone come with the profile.
Same buyer
A buyer at the register and a buyer online can share one profile. The name, email, and phone you already synced stay on that same person.
Starter
On Starter you run customer sync yourself. That fits a single location when someone on the team can start the sync after close.
Growth and Pro
On Growth and Pro you can turn on automatic customer updates. New buyers show up on the other system without a manual run.
Who it’s forSquare on the floor.
Square on the floor.
Shopify online.
For retailers who already sell in both places and want the catalog, stock, and customers to stay in step.
-
Keep the register
The floor team stays on Square POS. Shopify stays the store customers use online.
-
A count per store
Pair each Shopify location with the Square location that holds the same stock.
-
After a busy Saturday
CSV is fine once in a while. It fails when the wrong file goes out and Monday starts with a recount.
-
Manual, then automatic
Run sync yourself on Starter. Turn on automatic sync with Growth or Pro when volume picks up.
Setup
How the Shopify–Square sync works
Setup is a sequence, not a migration. You are connecting systems you already use.
-
01
Install from the Shopify App Store
Install SquareFloww from the Shopify App Store and approve access. The install path is the SquareFloww listing.
-
02
Connect Square
Authorize the Square account that runs your POS. You stay logged into Square. Nothing here closes your locations or swaps your card reader.
-
03
Map location pairs
Pair each Shopify location with its Square counterpart. One store maps one pair. Several stores map several pairs, up to your plan limit.
-
04
Pick the store your team edits
Match products by SKU or title. Then choose Shopify or Square as the store your team edits.
-
05
Sync when you are ready
Starter runs sync when you start it. Growth and Pro run automatic sync, and the activity log shows what each run did.
The activity log shows what each sync did. The step-by-step version is How to connect Square to Shopify.
Source of truth
Stop retyping the catalog after a busy day
The store you edit
Choose Shopify or Square as the store your team edits. Product changes start there, then copy to the other system.
What copies across
Product and stock updates copy from that store to the other one. You stop retyping the same catalog after every busy day.
Automatic updates
On Growth and Pro, automatic product updates copy from the store you edit to the other one. Starter stays manual until you are ready.

Alternatives
Why not Zapier, CSV, or switching POS?
A spreadsheet, a few Zaps, or a new register can each move something. None of them keeps Square and Shopify updated together.
CSV
A checked file is fine once a month. It misses the price that changed at the register after you exported.
Zapier
One Zap can send a new product across. Stock for each store, and the customer list, turns into several Zaps someone has to watch.
Switching POS
Shopify POS is the right move if you want one system. It means new hardware and a team that has to relearn the register.
Questions
Common questions
Square stays on the floor. This app syncs products, location inventory, and customers. It does not take payments.
Still have a question?Will this replace Square?
No. You keep Square POS. SquareFloww syncs products, inventory, and customers between the systems you already run.
Do I need automatic sync on day one?
No. Starter is manual, with one location pair. Move to Growth when you want automatic sync or more than one pair.
What if SKUs don’t match?
Link by SKU or by title. Clean obvious duplicates before the first sync so two similar names do not attach to the wrong item. Product rules are on Sync Shopify and Square products.
Does this process Square payments on Shopify?
No. Payments and Square Reader stay outside this app. Customer profiles are a separate sync: Sync customers between Shopify and Square.
Is there a free trial?
Yes. Seven days, started from the Shopify App Store. Cancel anytime through Shopify billing.
Does it replace Shopify POS?
No. Keep Square on the floor and sell online on Shopify.
