WooCommerce is a versatile and widely-used WordPress eCommerce plugin that offers extensive customization and scalability. It's free to install but may require additional costs for hosting, premium themes, or add-ons. WP EasyCart is a solid choice for small businesses with its quick setup, excellent customer support, and built-in Google Analytics integration. SureCart is a lightweight and secure option with a modern interface and headless setup, while Easy Digital Downloads excels at selling digital products. MemberPress is ideal for creating membership sites with granular control over content access and automated email reminders. When choosing an eCommerce plugin, focus on the tools you really need, avoid going plugin-happy, and consider automation to increase efficiency.
