Square and Squarespace Integration

How Square and Squarespace Integration Works

Payment Processing

Square can serve as a payment processor for your Squarespace Commerce store. When enabled, customers who check out on your Squarespace site have their payment processed through Square. The transaction appears in your Square dashboard alongside your in-person POS transactions, giving you a unified view of all revenue.

Inventory Sync

For businesses that sell the same products online (Squarespace) and in person (Square POS), inventory synchronization prevents overselling. When a product sells on either channel, the stock level updates on both. This requires either a direct integration or a third-party connector like Zapier.

Unified Reporting

With Square processing both online and in-person payments, your Square dashboard becomes a single source of truth for all revenue. You can track sales by channel, compare online vs. in-person performance, and generate financial reports that include both revenue streams.

Setting Up Square Payments on Squarespace

Step 1: Create a Square Business Account

Go to squareup.com and create a Business account if you do not have one. Complete the business verification process - Square needs your business details, bank information, and tax ID. The account is free - Square charges per-transaction fees with no monthly subscription for basic payment processing.

Step 2: Connect Square in Squarespace

In your Squarespace dashboard, navigate to Commerce > Payments. Look for Square in the available payment processors. Click Connect and authorize Squarespace to use your Square account for payment processing. Follow the prompts to complete the connection.

Note: Square availability as a Squarespace payment processor depends on your region. If Square does not appear in your payment settings, your region may not be supported for this direct integration. In that case, use Stripe (Squarespace's primary payment processor) for online payments and Square separately for in-person sales.

Step 3: Configure and Test

After connecting, verify Square appears as an active payment method. Place a test order to confirm payments process correctly through Square and the transaction appears in your Square dashboard. Check that order details (products, quantities, customer information) sync properly between both platforms.

Syncing Inventory Between Square and Squarespace

Using Zapier for Inventory Sync

If the direct integration does not include real-time inventory sync, use Zapier to create automated workflows. Set up a Zap that triggers when an order is placed on Squarespace and updates the corresponding product's stock level in Square (and vice versa). This requires mapping product IDs between both platforms.

Using Make (Integromat)

Make offers more complex data transformation than Zapier, useful for inventory sync with variant-level tracking, multi-location inventory, or bundle products. Build a scenario that watches for orders on both platforms and decrements inventory accordingly. For automation approaches, our guide to using Zapier with Squarespace covers workflow setup.

Manual Inventory Management

For businesses with a small product catalog (under 20 products), manual inventory management may be simpler than setting up automated sync. Update stock levels in both Square and Squarespace after each sale. This is error-prone at scale but workable for low-volume operations.

Square POS with Squarespace Online Store

Why Use Both

Many small businesses operate both a physical location (using Square POS) and an online store (using Squarespace Commerce). A restaurant with online ordering, a retail store with an e-commerce site, a salon with online booking and product sales - these businesses benefit from having Square handle all payment processing while Squarespace handles the web presence.

Transaction Fees

Square charges different rates for in-person and online transactions. In-person (card-present) transactions typically have lower fees than online (card-not-present) transactions. When Square processes your Squarespace online payments, the online rate applies. Check Square's current pricing for exact fee structures in your region.

Square vs. Stripe on Squarespace

Stripe is Squarespace's primary payment processor - it is the default option and has the deepest integration. Stripe handles credit card processing invisibly (customers see your checkout form, not Stripe's brand). It supports Apple Pay, Google Pay, and Afterpay on Squarespace.

Square is the better choice if you already use Square POS for in-person sales and want all transactions in one dashboard. Square's online processing fees are comparable to Stripe's.

Best practice for most businesses: Use Stripe for Squarespace online payments (deepest integration, most payment options) and Square for in-person POS. If unified reporting is critical, use Square for both and accept the slightly less integrated online experience.

Alternative: Square Online Checkout Links

If the direct payment integration is not available in your region, use Square's Online Checkout feature to create payment links. Add these as buttons on your Squarespace pages - customers click through to Square's hosted checkout to complete payment. This works on any Squarespace plan and does not require Commerce features.

Troubleshooting Square Squarespace Integration

Square Not Available as Payment Option

Square's direct Squarespace integration is region-dependent. If it does not appear in Commerce > Payments, your region may not be supported. Use Stripe for online payments and Square separately for in-person sales.

Orders Not Syncing to Square Dashboard

The integration may handle payment processing without full order detail sync. Verify in your Square dashboard whether orders show product-level details or only payment amounts. For full order visibility, a Zapier connector may be needed.

Inventory Discrepancies

If stock levels differ between Square and Squarespace, check whether automatic inventory sync is active. Without sync, a product sold in-store does not update the Squarespace listing. Set up Zapier-based sync or implement a manual inventory check routine. For site management best practices, our Squarespace SEO guide covers maintenance routines.

Unify Your Online and In-Person Sales

Square and Squarespace integration makes the most sense for businesses that operate both a physical location and an online store. Square processes all payments - in-person and online - while Squarespace provides the website, design, and content management. The result is a unified view of your entire business in one dashboard.

Connect the platforms, test the payment flow, set up inventory sync if needed, and let each platform do what it does best. Square handles the money. Squarespace handles the web presence.
