WooCommerce is a free plugin that gives WordPress everything an online store needs: a product catalogue, a cart, payments, order management and more.
Why WooCommerce
- Free and open source — the core costs nothing.
- Flexible — sell physical goods, digital products, services or subscriptions.
- Extendable — thousands of add-ons for payments, shipping and marketing.
It slots into your existing site: your pages stay exactly where they are, and a « store » section is simply added alongside them.
Key takeaway: WooCommerce = WordPress + e-commerce. It is the most widely used way to sell online.
