WooCommerce is a free, open-source ecommerce plugin for WordPress that turns a regular site into an online store. It lets you sell physical products, digital products, or both, while managing things like products, cart, checkout, payments, shipping, and orders from the WordPress dashboard.

What it does

  • Adds store features to WordPress.
  • Supports product listings, inventory, payments, and shipping setup.
  • Works for small shops and larger online businesses.

Why people use it
