What is Square POS × Bigcommerce integration?

A Square Bigcommerce Integration connects the products and inventory in your existing Square POS with the products and inventory in your Bigcommerce eCommerce. SKU IQ is the no-code connection layer between the two platforms. It is not a new POS, an ERP, or an inventory suite.

Square stays the POS. Bigcommerce eCommerce stays the ecommerce channel. Nothing migrates off either system.Whenever one platform sells something, the other will update the corresponding stock, keeping inventory numbers unified and up to date. Product attribute sync of fields like titles, descriptions, prices, variants, and SKUs can also be turned on either uni- or bi-directionally.

Unify both platforms and use SKU IQ to leverage the best they have to offer.

SOLUTIONS OVERVIEW

Why retailers connect Square POS and Bigcommerce eCommerce

Stop overselling

When a sale happens at the brick-and-mortar location or on Bigcommerce eCommerce, SKU IQ updates stock on the other platform, keeping inventory unified and up to date.

No double data entry

Stop entering the same product twice. When product attribute sync is on, supported product data such as titles, descriptions, prices, variants, SKUs, UPCs, and images can carry across based on your sync settings.

Keep systems you already use

SKU IQ is not a new POS, ERP, or inventory suite. It connects the Square POS and Bigcommerce eCommerce you already use, so both platforms stay in place while inventory stays unified and up to date.

Two ways to unify your inventory

Once Square POS and Bigcommerce eCommerce are connected, you tell SKU IQ how products relate across both platforms.

Link existing items

SKU IQ reads all inventory in both the Square POS and Bigcommerce eCommerce, checks for items matching by title/name, SKU, or UPC, and generates a Link Report so you can select what to link and how.

Products must have the same structure on both platforms to be linked. For example, a non-variable item in the POS will not match a variable set of items in the eCommerce platform.

Push a catalogue across

If products exist on only one platform, SKU IQ can send the chosen item data across, create an identical copy on the destination platform, and establish a syncing relationship between the new copy and the original so future stock changes are communicated automatically between both platforms.

Setup in minutes

What to expect during setup

SKU IQ does not require developers or code. If products already exist on both platforms, most retailers are syncing the same day.

1

Create your SKU IQ account

Select Bigcommerce eCommerce + Square POS.

2

Connect both platforms

Authorize both platforms through the guided flow. Your catalogues load in, and nothing is altered until you confirm it.

3

Run a link report

SKU IQ reads all inventory in both platforms and matches items by title/name, SKU, or UPC. Confirm the matches you want, remembering that products must have the same structure on both platforms to link. A non-variable POS item will not match a variable set in the eCommerce platform.

4

Review unmatched items

Fix spelling differences or push them across, which creates an identical copy on the destination platform and establishes a syncing relationship with the original.

5

Validate Sync

Validate the first sync with one or two products.

6

Choose sync & go live

Set optional product attribute sync as uni- or bi-directional.

Migrating a large catalogue

During the trial, customers are limited to 50 product pushes. Bulk pushes are available for larger catalogues for a one-time fee; contact Support for a quote.

When SKU IQ pushes a catalogue, it sends the chosen item data across, creates an identical copy on the destination platform, and establishes a syncing relationship with the original so future stock changes are communicated between both platforms.
