Now I am working in Wordpress CMS. But I want to know which CMS will be suitable for an e-commerce site?
There are many CMS scripts that you can use for your e-commerce shop. For example, you can use PrestaShop, Magento, or osCommerce. These three scripts are renown for their flexibility, advantages, and features. You can install them on your server for free because they're open source.
WordPress is excellent for ecommerce websites! WP has WooCommerce as their shopping cart system. Its easy to setup and customize too. You can also integrate WooCommerce with accounting and inventory software too.
