There are several different e-commerce solutions available, here are some of the ones available today:   Open source platforms: These platforms, such as WooCommerce for WordPress, are free and open for developers to modify and customize as needed. They are often more technically advanced and may require more technical expertise to use and maintain. SaaS platforms: Software-as-a-Service (SaaS) platforms, like Shopify, are hosted services where all maintenance, security, and upgrades are handled by the provider. These platforms are easier to use and require less technical knowledge. Custom solutions: For larger businesses or those with specific requirements, it may be appropriate to develop your own custom solution from scratch or by adapting an existing platform.   The choice of e-commerce platform depends on your company's specific needs and budget.
