Woocommerce

Woocommerce is the most popular open-source ecommerce plugin for WordPress, used by over 4 million online stores worldwide. It turns any WordPress site into a fully functional online store, letting you sell physical products, digital downloads, subscriptions, and even book appointments. You control everything — the checkout process, customer data, shipping options, and tax calculations. There are no fixed contracts or forced fees; you choose your own payment gateways and hosting provider.

The platform works by adding ecommerce capabilities to existing WordPress sites. Once installed, you can add products, manage inventory, set up shipping zones, and process orders from the WordPress admin panel. What makes Woocommerce stand out is its extensibility. The official marketplace offers hundreds of free and paid extensions for things like payment gateways (Stripe, PayPal, Square), shipping carriers, accounting integration, and memberships. Developers can build custom extensions using the WooCommerce REST API and hooks. The platform also supports in-person sales via payment terminals and integrates with services like Google Shopping and social media.

Woocommerce is ideal for anyone who wants to sell online without being locked into a proprietary platform. Small business owners can start with a simple store and add features as they grow. Agencies and freelancers build custom stores for clients, taking advantage of the open-source codebase. Large brands like Scrub Daddy, Mint Mobile, and Polestar use WooCommerce for their enterprise needs. It works for everything from selling handmade crafts to running subscription-based services. The trade-off is that you need some technical comfort with WordPress, hosting, and plugin management, though managed hosting providers simplify that significantly.
