Why Choose Square for WooCommerce?

Before jumping into the steps, let’s quickly look at why Square stands out as a payment gateway for WooCommerce stores:

• Multiple Payment Methods: Accept credit and debit cards, Apple Pay, Google Pay, and more.
• Sync Inventory in Real-Time: Keep stock updated between your online store and physical shop.
• Easy Dispute Management: Handle chargebacks directly within Square’s dashboard.
• No Hidden Fees: Pay only per transaction, with transparent pricing.

Step 1: Install and Activate the Square for WooCommerce Plugin

The first step is to add the official Square plugin to your store.

Now that the plugin is active, it’s time to connect your Square account.

Step 3: Configure Square Payment Settings

Next, you’ll want to fine-tune your settings to ensure everything runs smoothly.

• Enable Square as a payment option at checkout.
• Choose your transaction mode:
  • Sandbox Mode (for testing transactions).
  • Live Mode (for real payments).
• Select your default location for syncing inventory.
• Save changes.

At this point, your WooCommerce store is connected to Square, but testing is crucial before going live.

Step 4: Sync Products and Inventory

One of the biggest perks of Square integration is the ability to sync products and inventory.

• Go to WooCommerce > Settings > Integration > Square.
• Select Sync Products to push WooCommerce products into Square, or pull existing Square items into WooCommerce.

This ensures you’re never selling items that are out of stock—saving you from frustrated customers.

Step 5: Test the Checkout Process

Before opening your doors to customers, always test the setup.

• Enable Sandbox Mode in your Square settings.
• Place a test order on your site.
• Verify that the payment processes correctly and appears in your Square dashboard.

Once confirmed, switch to Live Mode to start accepting real payments.

• Payments Not Showing: Double-check if you’re in Sandbox mode or Live mode.

• Error Messages at Checkout: Try deactivating conflicting plugins or switching to a default theme like Storefront to rule out compatibility issues.
