Online Course E-Commerce Website

I need a modern e-commerce site dedicated to selling digital products—specifically, online courses. After checkout, learners must be enrolled automatically and able to track their lesson-by-lesson progress every time they log in. Authentication is already handled by our existing member account system, so the build has to integrate with that single sign-on rather than creating a new user database. The storefront should feel clean, mobile-first, and fast. Payments have to be processed securely (card and PayPal at minimum), and successful transactions should trigger immediate course access that shows a progress bar, completed-lesson indicators, and the option to resume where the learner left off. Deliverables • Responsive e-commerce front-end connected to the current member system • Course area with progress tracking and easy admin tools for uploading new lessons • Payment gateway integration with automated enrollment and confirmation emails • SEO-friendly structure, basic analytics, and deployment to our hosting environment • Short hand-off session so my team can add or modify courses without touching code Platforms such as WooCommerce with LearnDash, Shopify plus a digital-goods app, or a custom React/Node stack are all acceptable as long as they meet the requirements above.
