Online shopping

I'm looking to create an online shopping platform for hosting various digital and physical products, with a primary focus on delivering courses/training. I need something that is customizable and adaptable, so that I can adjust my services as needed, while still being user-friendly and easy to use. I want the platform to look modern, and the design should provide a comprehensive feature set that helps to make it an ideal platform for eCommerce. Ideally, I'd like for it to include features such as easy order processing, secure payment, inventory tracking, order history, customer reviews, customer loyalty, and newsletter integration. Finally, I want to make sure the platform is SEO friendly and compatible with all modern browsers.
