WooCommerce is very popular for a few reasons. First and foremost, it is a shopping cart plugin for WordPress, the most popular free CMS platform on the planet. WooCommerce is an excellent choice for smaller-budget companies and start-ups, but really shouldn’t be considered an enterprise-level solution. While it is possible to build a great WooCommerce site, it probably makes more sense to invest in a different platform if you’re looking for enterprise-level solutions. Because it’s essentially a plugin for WordPress, many of the typical benefits of WordPress apply for WooCommerce. Open-source, PHP, great plugins and development community, etc.. But, for scalability, security, and frankly, to be taken seriously, you probably want to look elsewhere.
