How to Accept Afterpay in WooCommerce [Step-by-Step Guide]

Buy-now-pay-later (BNPL) services have become one of the fastest-growing payment trends in e-commerce, enabling shoppers to split purchases into manageable installments without interest, provided they are paid on time. In fact, Digital Silk found that shoppers spent $18.2 billion using BNPL services in 2024.

As a shop owner, you definitely don’t want to miss out on such an opportunity.

Among these services, Afterpay is a massive name. Trusted by millions of users worldwide for its simple checkout experience and broad adoption across industries.

If you run a WooCommerce store, enabling Afterpay can help you attract more customers, and in this guide, we’ll walk you through the exact steps to integrate Afterpay into your WooCommerce store.

But before that, let’s take a moment to understand the service.

What is Afterpay?

Afterpay is a buy-now-pay-later (BNPL) payment service that allows customers to split their purchases into four equal, interest-free installments. Instead of paying the full amount at checkout, shoppers make the first payment upfront and then pay the remaining balance in installments every two weeks.

For customers, this makes shopping more manageable and budget-friendly. For merchants, it means more completed purchases and fewer abandoned carts.

Afterpay has gained widespread adoption worldwide, with millions of active users and partnerships across retail, fashion, electronics, and more. 

Its popularity comes from its simplicity: no hidden fees for shoppers who pay on time, and merchants receive the full payment immediately, while Afterpay handles collections.

Why Accept Afterpay in WooCommerce?

Adding Afterpay to your WooCommerce store helps keep up with customer expectations.

As we mentioned earlier, shoppers today prefer flexible payment options that simplify the management of larger purchases. By offering Afterpay, you open the door to a broader audience and give your business a competitive edge.

Here are some key benefits:

• Increased Conversions: Many buyers abandon carts when faced with high upfront costs. Afterpay reduces this friction by letting them spread payments out, making it more likely they’ll complete the checkout.
• Larger Average Order Value (AOV): With installment payments, customers often feel more comfortable adding extra items to their cart, leading to higher order totals.
• Appeal to Younger Shoppers: Millennials and Gen Z are heavy users of BNPL services. Accepting Afterpay positions your store to attract and retain this valuable demographic.
• Instant Full Payments for Merchants: Afterpay pays you the full amount upfront, while handling the collection process from the customer, so you don’t have to wait for the remaining payment.
• Build Trust and Loyalty: Displaying Afterpay as an option shows you care about affordability and accessibility, encouraging repeat purchases from satisfied customers.

3 Easy Steps to Accept Afterpay in WooCommerce

WooCommerce, by default, doesn’t provide a built-in option to accept Afterpay. To make it work, you need a third-party solution that can integrate BNPL functionality into your store.

The solution for it is the WC Shop Sync WordPress plugin. It seamlessly integrates WooCommerce with Afterpay and other payment services, ensuring a smooth checkout experience and providing the flexibility to manage transactions from a single location. 

We’re choosing this plugin for our walkthrough because it’s feature-rich, reliable, and built specifically to handle integrations like Afterpay with minimal setup—more on this later. 

Before proceeding with the integration, here are the prerequisites to keep ready.

Prerequisites For Installing WC Shop Sync

Before you start integrating Afterpay with WooCommerce, make sure you have the following in place:

• A WooCommerce Store: You’ll need a WooCommerce store already set up on WordPress. This includes basic configurations like products, checkout, and order management.
• WC Shop Sync Plugin: Download and install the WC Shop Sync plugin. This will serve as the bridge between WooCommerce and Afterpay, along with other supported payment services.
• A Square Developer Account: Since WC Shop Sync relies on Square’s payment infrastructure, you’ll need a Square Developer account. From here, you can generate the required API credentials for integration.
• SSL Certificate Installed: To securely process payments, your website should run over HTTPS. This ensures sensitive customer data is encrypted during checkout.
• Updated WordPress & WooCommerce: Always ensure both WordPress and WooCommerce are updated to the latest versions. This avoids compatibility issues during the installation process.
• Basic Admin Access: You should have WordPress admin-level permissions to install plugins, configure payment gateways, and manage API keys.

With these essentials ready, you’ll be set to move smoothly through the installation steps without interruptions.

Step 1. Install WC Shop Sync

Before jumping into the Afterpay setup, the first step is to install WC Shop Sync on your WooCommerce store. This plugin acts as the bridge between your store and Afterpay.

1. Navigate to your WordPress dashboard and go to Plugins → Add New. 
2. Use the search bar to find “WC Shop Sync” 
3. Click Install Now 
4. Wait for completion and click Activate. 

Once activated, the plugin is ready to connect your store with Afterpay and other payment services, setting the stage for a hassle-free BNPL integration.

Step 2. Connect With Square

As discussed, WC Shop Sync connects Square with WooCommerce. This allows for using the Square payment gateway to accept payments through various payment methods, including BNPL services, mobile wallets, ACH payments, and Square gift cards.

Here’s how to connect both:

1. Navigate to WC Shop Sync settings and switch from Sandbox to Production—the sandbox is used for testing payments before accepting them on your site. Once the payment process is smooth, switch to Production, and users can proceed with real payments.
2. Click Connect with Square.
3. On the subsequent screen, use your Square developer account’s login credentials to log in to your Square account.
4. Square will ask for the necessary permissions

5. Review and click Allow.
6. Next, you will be redirected to the following screen. Click “THAT’S MY SITE – REDIRECT ME.”

There you have it. You just connected Square with WooCommerce!

Now, integrating Afterpay is just a few clicks away.

Step 3. Enable Afterpay

1. Navigate to payment settings.

2. Scroll down until you find the Enable After Pay checkbox.

3. Check it and click Save changes.
4. Now head back to WooCommerce settings → Payments.

5. Toggle the Square After Pay button and click Manage, as shown in the image.

6. On the subsequent screen, you will see these options, as shown in the image. Check the Enable Square After Pay checkbox, give it a title, add a small description, and save changes.

There you go! Now, you can accept Afterpay in WooCommerce. 

Here’s how it should look on the front-end.
