YoKart has a couple of downsides, though. Given the robust structure, customizing YoKart will require a developer with extensive knowledge of PHP. Also, it's not open source like Magento. The Startup and GoQuick Packages offer default themes. And, unlike Magento, YoKart is primarily focused on SMB, which means the needed features are already available in standard packages; for large scale enterprises, customization would be a must do.
Version 1.2.0 of WooCommerce Blocks is now available as a feature plugin. It’s the easiest, most flexible way to display your products on posts and pages! Using the original “Products Block”, your displayed products can be filtered by category, sale status, or a variety of other fields. You can even make a custom list of handpicked products to display.
Shopify is another strong ecommerce software option. Their mission is to make selling online as fast and simple as possible. They nailed that, but their SEO has some holes. Weak ranking performance, rigid URL structures and a WordPress plugin that uses iFrames highlights my concerns with their SEO. Moreover, you can’t customize Shopify’s checkout page.
Bigcommerce also has a nice library of themes for you, divided into multiple categories, and all of them responsive and fully customizable. They were developed to establish a more modern, fluid user experience, utilizing cool new merchandising features for categorization and differently sized catalogs. There are both free and paid options available, and I have to say that those free ones really are attractive-looking.
