Imagine a customer reaching the payment form on your WordPress site, seeing the high total, and leaving instantly. This is one of the biggest reasons behind lower payment form conversion and abandoned payments on WordPress sites.

Adding a Buy Now Pay Later payment option reduces purchase friction by letting customers split payments into smaller installments. Since WordPress doesn’t include built-in payment functionality, site owners rely on plugins like WP EasyPay to accept payments through custom forms.

Now this is backed by numbers: Buy Now Pay Later WordPress usage grew by 34.5% in 2025, and is expected to rise another 19.2%.

The good news? Setting up BNPL in WordPress is simple and takes just a few steps.

In this guide, we’ll walk you through what BNPL is and how to add a Buy Now Pay Later payment to your WordPress site.

Buy Now Pay Later works especially well for WordPress sites that collect payments through forms, such as service bookings, donations, subscriptions, or one-time payments.

What is Buy Now Pay Later in WordPress?

Buy Now Pay Later (BNPL) is a flexible payment solution that allows customers to purchase products immediately and pay in smaller, scheduled installments (also known as Buy Now Pay Later payment plans) rather than paying the full amount at once.

BNPL typically appears within the payment form as a selectable payment option. For instance, if you are planning to purchase a tech gadget, you will see a “pay later” option. There are preset payment plans that you agree to and complete the order.

The BNPL provider pays the full amount to the store upfront; meanwhile, the customer pays the BNPL provider in installments. If you’re unfamiliar with how transactions flow behind the scenes, understanding how payment processing works can give you better insight into BNPL systems.

One of the most popular BNPL providers is Afterpay. You can easily set up Afterpay in WordPress using WP EasyPay to maximize conversions.

Benefits of Adding BNPL to WordPress

Adding a Buy Now Pay Later service to your payment options on your WordPress site directly helps turn more visitors into paying customers.

• Fewer abandoned payments: When customers see a Buy Now Pay Later payment plan, the total feels smaller and more manageable.
• Higher order value: A shopper who might buy one item becomes more likely to add two or three, because the immediate cost stays low.
• More payment flexibility for customers: Buy Now Pay Later payment plans provide flexible payment options and give customers full control over their budget.
• Competitive advantage: Many WordPress sites still don’t offer Buy Now Pay Later options. Adding it puts you ahead of competitors who accept cards as the only method for online payments.

Best Practices for Displaying BNPL on WordPress Pages

Setting up BNPL is only half the job. How you display it matters just as much. If customers don’t notice the option, they won’t use it, and you lose the conversion benefit entirely.

In fact, many WordPress site owners unknowingly make common payment method mistakes that reduce conversions, especially when introducing new payment options like BNPL.

Here’s what actually works:

• Show it early, not just at payment form

Don’t wait until the payment form to mention BNPL. Add a small line on your product detail pages right below the price, something like “Pay in 4 installments with Afterpay.” Customers who see this early are already mentally budgeting before they even proceed to the payment form

• Use payment form page banners

Place a visible banner or notice at the top of your payment form page to remind customers that BNPL is available while choosing a payment option in the form. At this stage, a customer is already close to converting. A simple reminder can push them over the line.

• Keep the messaging simple

A short line like “Split into 4 easy payments” works better than a paragraph of terms. Customers want to know one thing: will this cost me less right now? 

• Make your payment form easy to find

If you’ve embedded your WP EasyPay payment form on a dedicated page, link to it from your navigation menu or product pages. The fewer clicks it takes for a customer to reach the BNPL option, the better.

• Test before going live

WP EasyPay lets you run sandbox payments before switching to production mode. Use this to check that your Afterpay integration works correctly, the form loads properly, and the confirmation message appears as expected. Don’t launch it untested.

Increase Your Conversions with BNPL Options

When a customer sees a large total on a payment form, the easiest decision is to close the tab. In simpler terms, we can all collectively agree that price can be one of the biggest hesitation factors when purchasing anything.

Buy Now Pay Later removes that hesitation. It breaks a full payment into smaller, manageable installments, making the same product feel much more accessible. 

The result? 

Higher average order values and customers who are more likely to return.

The best part is that you don’t need a developer to make it happen. With WP EasyPay, you can integrate Afterpay directly into your WordPress site in just a few steps. From connecting your Square account to publishing your payment form, the entire process is straightforward and built for store owners who want results.

If you’re serious about growing your store and expanding your WordPress payment flexibility, BNPL is a must-have.
