Running an online store while managing physical sales often means juggling two systems. Product data, inventory levels, and pricing can quickly fall out of sync.
This disconnect can create confusion, as staff may sell items that are already out of stock. Customers might see different prices online and in-store.
The solution is a unified system that enables both platforms to communicate in real-time. This way, every change is reflected instantly, without requiring manual updates that are prone to human error.
In this guide, you will learn how syncing Square POS with WooCommerce brings consistency and how to do so effectively.
Why Sync Products Between Square POS and WooCommerce?
Maintaining consistency between your physical and online storefront is essential for operational accuracy and customer trust. Here is why syncing products matters:
- Helps avoid overselling. When inventory updates in real time, you prevent situations where an item sells online but is already out of stock in-store. This protects your reputation and reduces the number of refund requests.
- Saves time on manual updates. Without synchronization, every product change must be entered manually twice, in WooCommerce and Square. Automation eliminates duplicate work, freeing up your time for more valuable business tasks.
- Ensures consistent pricing. Price differences between platforms can confuse customers and damage credibility. A synced system ensures that your prices stay uniform across all sales channels.
- Improve inventory management. With synced stock levels, you can track product performance more effectively. It also helps in planning reorders and understanding which items sell faster in a specific location.
- Offer a better customer experience. Customers expect accuracy whether they shop online or in-store. Syncing both platforms creates a unified brand experience across touchpoints.
- Reduce human error. Manual data entry is prone to mistakes. Automated syncing keeps your records accurate and up-to-date, reducing the risk of costly mismatches or lost sales.
If this feels convincing, the following sections can help you sync products between Square POS and WooCommerce.

There’s more to the plugin, but that’s a topic for later in this article.

You can upload that file from Plugins ⇒ Add Plugin ⇒ Upload Plugin in the top left corner ⇒ Choose File ⇒ Browse where you downloaded the plugin ⇒ Enter the license key in the input box.
You can now use all the premium features. Which takes us to our next step.
Step #2. Connect With Square
Go to WC Shop Sync’s settings.
Sandbox enables testing the payment before allowing real customers. It helps find and fix potential issues before customers face them. You can use the production tab after you have finished testing payments and are certain that customers will not encounter any issues.
After selecting the Production tab, click Connect with Square.
You will be redirected here to the Square Sign in page. Use your login credentials or create a new account if you don’t already have one.
Then Square will ask for certain permissions, scroll down, and click Allow.
Doing so will redirect you to the following screen. Click THAT’S MY SITE – REDIRECT ME.
Now you have it! The Square has been connected, and we can proceed to the next step.
Step #3. Enable Product Synchronization
After the Square is connected, click Access your Module.
This should take you to the plugin’s module. That’s where you can enable/disable or configure features based on your preferences. Here’s how it looks.
Toggle the first button open at Synchronization of Products, and click the Settings button that appears after activation.
This page allows for further customization of the synchronization.
Firstly, use the Auto Synchronization feature and select the drop-down to specify when it should be automatically synced. You can select from 1, 12, or 24 hours.
Next, you can choose between merging options:
- WooCommerce products override — Products on WooCommerce will override the data of the items on Square
- Square products override — Items on Square will override the data of the Products on WooCommerce
Afterward, choose your sync preferences that whether you want all the products to be synced or specific ones.
Real synchronization occurs with every edit. There can be miscommunication and misjudgments when you edit the price on Square, and it hasn’t been imposed on WooCommerce. With WC Shop Sync, you can address this issue by utilizing the ‘Sync on edit’ feature in WooCommerce.
After clicking it, check the boxes before what you want to sync after edit including, title, description, price, stock, category, and product image. Any box not checked, will not be synced and vice versa.
Similarly, scroll down and set the plugin as you like.
Once done, click Save Changes.
Alternatively, you can also manually sync them using the Synchronize Woo To Square or Synchronize Square to Woo buttons.
There you have it! Now, every time you add a new product, you don’t have to manually enter it repeatedly. Download WC Shop Sync today and save tons of time!
