I think it depends more on the theme’s WooCommerce compatibility than WordPress itself. Most modern themes can handle an eCommerce setup if they are built properly, but I would always check things like product pages, checkout design, mobile responsiveness and plugin support before choosing one. A good theme can make the whole store setup much easier.
Yes, a WordPress theme can support an e-commerce website, especially when it is compatible with WooCommerce. Choose a responsive, fast-loading theme that supports product pages, shopping carts, secure checkout, and payment integrations. Also, check plugin compatibility and customization options to ensure a smooth shopping experience across all devices.
