WooCommerce

WooCommerce (often shortened to Woo) is the most widespread open-source e-commerce plugin for the WordPress content management system. It turns an ordinary website into a fully functioning online store. Thanks to its modular nature it makes it possible to sell anything, from physical products and digital content to subscriptions and bookings. Unlike closed systems (SaaS), WooCommerce gives the owner complete control over the e-shop's code, data and design.

WooCommerce powers roughly 25% to 30% of all e-shops in the world. Its success lies in being built on WordPress, which lets owners combine first-class content marketing (a blog) with advanced selling.

Key features

A free core: the plugin itself is free; you pay for hosting, a domain and premium features.
Extensibility: thousands of paid and free extensions make it possible to add features such as XML feeds, carrier integrations or advanced filters.
Community: an enormous global developer community guarantees continuous development and bug fixes.
Custom adaptation: because the code is open, a developer can tailor any part of the purchase process.

Advantages

Ownership and control: the site and the data are yours. You are not tied to monthly platform rental fees that could rise at any time.
No sales commission: the platform takes no percentage of your turnover (you pay only your payment gateway's fees).
Excellent SEO: running on WordPress, WooCommerce benefits from the best search engine optimisation tools on the market.
Design flexibility: you can create an e-shop with a unique look that does not resemble a template solution at all.
Scalability: with the right hosting, WooCommerce can handle anything from dozens to thousands of orders a day.

Disadvantages

Technical responsibility: updates, backups and security are down to you (or your agency). Neglected maintenance can lead to errors or the site being compromised.
Hosting demands: as an e-shop grows it requires more powerful server resources than simple SaaS solutions.
“Plugin hell”: too many add-ons installed from different authors can cause incompatibility and slow the site down.
Higher initial investment: a quality setup and bespoke visuals from professionals cost more at the outset than a monthly subscription to an off-the-shelf solution.

Practical example

A specialist book publisher wants an e-shop that doubles as a lifestyle magazine.

A SaaS solution does not let them build the complex blog and visual layout they have in mind.
They choose WooCommerce. With it they get a first-class articles section connected directly to the products in the basket. When they publish a new book they link it to a review in one click and set automatic discounts for loyal readers. The whole site feels like a distinctive magazine rather than “another e-shop in the row”.
