Top 5 Most Popular Australian eCommerce Platforms

Which eCommerce platforms are leading in Australia? Let’s take a look at the top 5 platforms dominating the Australian eCommerce market. These platforms power over 40% of online stores in the country. Knowing them will help you make an informed decision about where to integrate your SaaS app.

1. Shopify: A Dominant Force in Australia

Shopify is undoubtedly a favorite among Australian online store owners. With over 40,000 merchants using the platform, Shopify’s market share in Australia stands at approximately 18%. Additionally, its easy integration with tools like the Australian Post app makes it a seamless option for local eCommerce businesses. Shopify’s ability to enable businesses to generate more than 100 billion dollars in sales speaks volumes about its success and popularity.

2. WooCommerce: The Go-To for WordPress Users

For businesses looking to leverage the power of WordPress, WooCommerce is the ideal solution. With more than 28,000 Australian e-commerce stores using WooCommerce, it has a 13% market share. This free plugin transforms any WordPress site into a fully functional online store, especially for merchants selling digital products, services, or even physical goods. WooCommerce’s flexibility and cost-effectiveness make it a top choice for small to medium-sized businesses.

3. Squarespace: Beautiful, Minimalist eCommerce

While not as widely used as Shopify or WooCommerce, Squarespace has earned its spot with 15,000 Australian e-commerce sellers. It offers sleek templates and easy-to-use features. With a market share of over 7%, Squarespace is popular for businesses looking for an elegant, minimalist online store with fast load times and excellent integration options. If you prioritize design and user experience, Squarespace might be the perfect fit.

4. Magento: Full Control for Experienced Users

Magento is a favorite among developers and businesses that require full customization. More than 5,400 Australian merchants use Magento, and its market share is approximately 3%. This open-source platform offers complete flexibility, making it ideal for high-volume businesses. While it may require a developer to build and maintain a custom site, Magento provides businesses with the freedom to scale and control their online store. It's best suited for companies that need advanced customization.

5. BigCommerce: Ideal for Larger Brands

BigCommerce serves over 3,200 Australian e-commerce stores and holds a 2% market share. This platform is built for large-scale businesses, providing advanced features and the ability to manage a massive volume of transactions. BigCommerce is the go-to platform for brands looking to expand their reach and manage a growing customer base effectively. Its powerful tools and scalability make it ideal for enterprises looking to scale rapidly.

Why is It Important for SaaS Providers to Integrate with These eCommerce Platforms?

As a SaaS app provider, connecting with the leading Australian eCommerce platforms is crucial for accessing a large market of potential customers. In Australia alone, tens of thousands of e-shop owners rely on these platforms to manage their online stores.

By integrating your solution with these platforms, you can empower eCommerce store owners to automate their operations, gain full control over inventory, orders, and customer data, and improve the overall efficiency of their business. This is a vital step toward enhancing the user experience and providing more value to your clients.

Moreover, integrating with these platforms will help you offer superior services to your clients. While you can provide your service without API integration, your clients will struggle to fully manage their products, stocks, and inventory. By connecting to multiple platforms at once, you can streamline operations, ensuring that data is automatically updated and synchronized across all systems. This approach significantly reduces errors and manual work, which ultimately boosts productivity.

Finally, integrating your SaaS app with Australia’s top eCommerce platforms will give your clients a competitive edge. Helping your clients stay ahead in the market not only strengthens your relationship with them but also encourages word-of-mouth recommendations, which will ultimately grow your customer base.
