TL;DR
- WooCommerce is an open-source e-commerce plugin for WordPress.
- It turns an existing WordPress site into a store.
- You own the store and the data; hosting and extensions are the real costs.
- Features, extension terms and prices change, so check the current pricing before you commit.
- It is not a hosted all-in-one platform: you still run hosting and updates.

What WooCommerce is
WooCommerce is software you add to WordPress rather than a standalone store hosted for you.
The core product is the plugin: it adds products, carts and checkout to a site you already run.
Around the core it adds payments, shipping, tax and orders, with extensions for anything more specialised.
Because it runs on your WordPress site, you choose the host and you look after updates, backups and speed.
How WooCommerce is organised
Everything hangs off your WordPress site. Products are a content type, and orders, customers and coupons sit alongside them.
You create products, set prices and stock, then connect payments and shipping at checkout.
The core is free; extra capabilities come as extensions, each added to the same site.
As the store grows you scale the host, add caching, and add extensions rather than change platform.
What WooCommerce is good at
- Owning your store, data and customer relationships.
- Customising design and checkout with full control.
- Selling unlimited products without a platform plan.
- Extending with thousands of plugins for niche needs.
- Running a store on a platform you already know.
What WooCommerce is not
- Not a hosted service: you manage hosting, updates and security.
- Not turnkey: setup takes more work than a hosted store builder.
- Not inherently fast: performance depends on your host and setup.
- Not free in total: the plugin is free, but hosting and extensions are not.

Frequently asked
Is WooCommerce free?
The plugin itself is free and open source. Hosting, domains and extensions are the real costs, so check current pricing before you budget.
Do I need WordPress?
Yes. WooCommerce is a plugin, so it runs on a self-hosted WordPress site rather than on its own.
Can it handle a small store?
Easily. It scales from a handful of products to large catalogues, with hosting being the main limit.
Do I need to code?
Not for basic selling, but customisation and performance work benefit from some technical comfort.
Is it better than a hosted store builder?
It depends. WooCommerce wins on ownership and flexibility; hosted builders win on hands-off simplicity.
