How to Add a Custom Payment Method in WooCommerce [3 Easy Steps]

Although WooCommerce offers plenty of payment options, sometimes, those defaults just aren’t enough. For example, you cannot neglect the importance of digital wallets, as they captured 53% of transactions in 2024.

Maybe you’re working with a local provider. Or you’re building a workflow that doesn’t fit the default WooCommerce payment methods.

In such cases, you need a custom payment method in WooCommerce.

The process of adding a custom payment method in WooCommerce involves customizing the checkout experience to meet your business’s needs as well as the user’s habits and operational logistics.

This guide will walk you through exactly how to do that, step by step. 

What is a Custom Payment Method in WooCommerce?

A custom payment method in WooCommerce refers to any payment option added other than the platform’s default offerings.

These include alternatives that are not part of the default payment options. Whether you want to accept cryptocurrency or offer credit card payments, or use mobile wallets. etc., all of these are considered custom methods.

In terms of functionality, a custom payment method provides you with the flexibility to tailor WooCommerce to your specific business needs. For example, if you operate in a region where international payment gateways are either unsupported or impractical, you may need to add a local payment service provider that better suits your customers’ needs.

What makes a payment method “custom” is not necessarily the technology involved but the fact that it does not come prepackaged within WooCommerce. 

It requires either code-level integration or a plugin designed to support these types of payment methods. 

WooCommerce only offers the following payment options by default in the United States—the options may change depending on your location. Anything other than these is a custom payment option.

Why Add a Custom Payment Method in WooCommerce?

The BNPL market reached $340 billion globally in 2024. This highlights the wide usage of multiple payment options worldwide. This is one of the main reasons why store owners are adding custom payment options to their stores.

Here are some other reasons:

• Support for local payment gateways. Many regions prefer payment options that are not natively supported by WooCommerce. If your customers like or trust these payment options, adding them directly into your checkout flow improves conversion and builds confidence.
• Integration with local payment services. If your store integrates with a proprietary platform or a niche payment service provider, chances are it will not be compatible out of the box. A custom payment method allows you to bridge that gap without disrupting the checkout experience.
• Better control over payment flow. Some store owners need granular control over payment flow. Whether it’s conditional logic, custom email handling, or triggering third-party APIs, a custom method gives you complete authority over how you control the payment flow.

Custom payment methods make WooCommerce significantly more adaptable. You can tailor the platform to suit your work style.

Prerequisites For Adding Custom Payment Methods

Before adding custom payment methods to your WooCommerce store, it’s helpful to understand the technical and strategic requirements.

First and foremost, you must download WC Shop Sync.

WC Shop Sync is a plugin that allows store owners to add multiple custom payment methods without writing any code. 

We will cover this in detail later, but for now, let’s review a few key items you should have ready before proceeding with the process.

Make sure you meet the following requirements:

• WC Shop Sync. The plugin that helps with adding custom payment methods.
• A functional WooCommerce Store. Ensure you have the latest version of WooCommerce for your store. 
• Square Seller Account: WC Shop Sync connects with Square to allow custom payment methods in WooCommerce.
• Administrator Access. If you are doing it for someone else’s business, ensure you have administrator access or specific roles that allow you to manage plugins.

Once these pieces are in place, you are ready to begin configuration with WC Shop Sync. 

3 Steps to Add a Custom Payment Method in WooCommerce

Let’s start the integration by downloading WC Shop Sync. 

Step 1. Install and Activate WC Shop Sync

To do this, go to your WordPress dashboard, then navigate to Plugins> Add Plugin > Search for WC Shop Sync, activate, and install the plugin.

Step 2. Connect WC Shop Sync With Square

Now, let’s connect WC Shop Sync with Square. If you don’t have a Square account, please create one before proceeding with the process. 

Choose between the Sandbox and Production modes. The sandbox option allows for testing payments before accepting them. It enables you to find and fix potential problems and glitches before actual users run into them. Conversely, the production mode that allows for accepting payments, we recommend using Production mode only after ensuring the payment gateway system works perfectly fine in the Sandbox mode. 

After selecting the better option, navigate to the plugin’s settings and initiate the process by clicking the “Connect with Square” button.

On the subsequent screen, you would be required to log in to your Square account. Enter the login credentials of the account.

Square will ask for certain permissions. Review and click Allow.

Why We Chose WC Shop Sync?

They do not address the broader ecosystem of how your store operates—things like syncing inventory, maintaining product consistency across platforms, or streamlining multi-store workflows.
