Marketing the WooCommerce Plugin
Over 6.5 million websites (and counting) run on WooCommerce, one of the market leaders in e-commerce. In 2023, Statista reported that open-source WooCommerce had a market share of 39%.
While each of the major e-commerce platforms can create a good experience for merchants and shoppers, WooCommerce's plugins are one of the most important reasons store owners use the platform. They offer a powerful way for e-commerce operators to have complete control over each product page and fine-tune user experience.
In this article, we delve into the 9 major steps of creating a WooCommerce plugin.
What is WooCommerce Plugin Development?
WooCommerce Plugin Development refers to the process of creating custom plugins specifically for WooCommerce, the popular e-commerce platform built on WordPress.
WooCommerce plugin development involves coding, testing, and deploying plugins that meet the unique needs of a store, such as custom payment gateways, shipping methods, or product enhancements. This process requires knowledge of PHP, WordPress, and WooCommerce's core structure.
Benefits of WooCommerce Plugins
Customizing WooCommerce plugins can help you streamline store operations, saving time and reducing errors all along the sales pipeline. Custom plugins can also enhance store security, improve analytics, boost scalability, and provide seamless integration with customer service, ordering, and shipping.
Above all, a custom WooCommerce plugin can provide your or another WooCommerce store with the functionalities you need, supporting your branding and customers as it helps your store grow and scale.
1. Do You Need Custom Plugins for WooCommerce?
Simple WooCommerce stores that don't ship internationally and have a small selection of merchandise probably don't need several approach versions of creating a WooCommerce plugin.
Larger stores, those that ship internationally, and stores that provide extensive customization may benefit from customized WooCommerce plugins. Here are a few of the scenarios where a custom plugin can help a WooCommerce store:
- Unique and custom products – Enhancing customer choice and providing accurate information for customized products.
- Specialized checkout options – Integrating subscription services, tiered memberships and benefits, and adjustable checkout options.
- Custom shipping and delivery – Using local delivery services or needing complex shipping rules to determine costs.
- Personalized marketing and advanced loyalty programs – Offering customized loyalty programs, product/service bundles, and discounts tailored to specific market customers.
- Integration with external platforms – Integrating with ERP and CRM systems, as well as third-party APIs, including payment gateways.
- Regulatory compliance – Meeting complex international tax and privacy compliance requirements.
- Security – Customizing and enhancing security features.
While there are thousands of WooCommerce plugins available, many of them can have gaps that can affect how your store operates. WooCommerce plugin experts can not only help to identify any gaps in your current plugins, but they can also help you determine if custom WooCommerce plugin development can benefit your store.
2. Prerequisites for WooCommerce Site Plugin Development
Once you understand your e-commerce business needs, you can prioritize the functions you need in a customized WooCommerce plugin. Developing a good WooCommerce custom plugin requires some essential tech skills, including:
- PHP Proficiency. WooCommerce uses PHP as its basic language, so the ability to write and debug in a PHP file is essential, along with the understanding of OOP (Object-oriented programming) for plugin coding.
- WordPress and WooCommerce hooks. WooCommerce interacts with WordPress through APIs, while store features and functions depend on templates and hooks, which include important actions and filters.
- Web technologies. Knowledge and ability in HTML, CSS, and JavaScript along with jQuery.
- Database interactions. Along with the ability to work with WordPress Database API, and understanding SQL to interact with complex databases and plugin files.
In addition, you should have a strong understanding of WordPress and WooCommerce security best practices, proper version control, including source code management, and REST APIs for interaction with external systems.
3. Consider Hiring WooCommerce Developers
To simplify the process and skip most of the next steps, look for experienced WooCommerce plugin developers who are also good WordPress plugin developers. Ask for references, and investigate successful projects they've completed, including wp-content plugins. The right specialists will be responsive, transparent, and immediately able to answer your questions and understand your e-commerce features and functionality needs.
4. Setting Up Your Development Environment
To successfully create and install a customized WooCommerce plugin, you need to first have a secure, stable local development environment. This includes a local server stack enabled with tools like XAMPP, WAMP, MAMP, or Local by Flywheel.
Why? You need a local server with a local database and a PHP environment that can run WordPress locally during the development process.
After you have the secure local server set up properly, you'll need to install WordPress and WooCommerce locally. Use these to put in test products, product categories, and various functionalities.
5. Structuring Your Plugin
The quality and functionality of your customized WooCommerce plugin are directly related to how well you've structured it. Here's a recommended, reliable method to structure the plugin:
- Root Directory – Use a solid naming convention for the root directory with hyphens, like 'this-awesome-custom-woocommerce-plugin'.
- Main plugin file – Create your primary plugin file using the same convention, like 'this-awesome-custom-woocommerce-plugin.php'.
At the top of the file, include your essential metadata:
<?php
/**
* Plugin Name: This Awesome Custom WooCommerce Plugin
* Plugin URI: https://example.com/this-awesome-custom-woocommerce-plugin
* Description: A custom plugin for WooCommerce that adds special functionality.
* Version: 1.0.0
* Author: Your Name
* Author URI: https://example.com
* License: GPL v2 or later
* Text Domain: this-awesome-custom-woocommerce-plugin
* Domain Path: /languages
*/
Here's how a file structure could look for your plugin:
this-awesome-custom-woocommerce-plugin/
├── assets/
│ ├── css/
│ ├── js/
│ └── images/
├── includes/
│ ├── class-this-awesome-custom-woocommerce-plugin.php
│ └── class-this-awesome-custom-woocommerce-plugin-settings.php
├── languages/
├── templates/
├── vendor/
├── uninstall.php
├── this-awesome-custom-woocommerce-plugin.php
└── README.txt
A readme.txt file is important to document your work. Here's an idea of what one could look like:

6. Implementing Plugin Functionality
To implement the plugin's functionality, you'll use WordPress's plugin API, which allows you to hook into WordPress to change the default behavior and add new features and functionality to its core code.
You'll customize your plugin's interactions with WordPress through action hooks, which will run the custom function when WordPress initializes. You can also modify data before WordPress uses it with filter hooks.
Prevent security vulnerabilities by using best coding practices, including sanitizing input and escaping output.
7. Testing and Debugging Your WooCommerce Plugin
Testing and debugging is a crucial part of the custom WooCommerce plugin development process.
Tools like Xdebug and browser developer tools for each browser (Chrome, Firefox, etc.) can help you to test and debug by simulating scenarios that the plugin could encounter before ensuring WooCommerce is active. However, these tools can't always simulate how humans will behave. So, manual, hands-on testing is also important.
There are a few common issues that can arise during the testing and debugging phase. Debug the checkout process to fix problems like missing fields and payment gateway issues. You can also check for database table problems using phpMyAdmin. Sometimes problems can be solved by clearing browser and site caches.
8. Compliance and Best Practices
Developing a good WooCommerce custom plugin includes understanding and adhering to both WordPress plugins and WooCommerce extension coding standards. For example, WooCommerce and WordPress are designed to work with a standardized database schema, so you should avoid creating custom database tables unless it's absolutely necessary.
Documentation and user support are also essential, including proper documentation within the plugin and for the overall site. You can use code comments to support the process. At a minimum, provide an installation guide for automatic and manual installation, as well as configuration steps. Providing a feature-by-feature walkthrough is another best practice that you should aim to follow.
9. Marketing the WooCommerce Plugin
You can promote your custom plugin by developing a custom website for your plugin, optimizing it for SEO, and creating a solid landing page. You can also engage with the WooCommerce ecosystem, including the Marketplace and support forums to spread the word and market your plugin.
Besides, there are many online communities for e-commerce businesses, including social media-based communities and user communities. You can find these communities via social platforms like Reddit, Facebook, and different WordPress and WooCommerce support and community sites.
