E-Commerce Digital Products Website

I’m building a clean, fast e-commerce site that will exclusively sell downloadable digital products—think templates, presets and small software utilities. A friction-free customer journey is critical, so I need the full design and development handled from concept through launch. The must-have feature is a built-in product-review system that lets buyers leave ratings and feedback right on each product page; this piece should look polished, load quickly and be easy for me to moderate from the back end. While the core requirement is reviews, I’m open to your guidance on whether to layer in a shopping cart or direct-to-checkout flow and which payment gateway would pair best with digital delivery. Please advise on the platform you feel suits this scope—WooCommerce, Shopify, custom React + headless CMS, or any other stack you’ve proven works for digital downloads—and outline how you’ll handle: • Responsive UI/UX design that keeps page weight low for fast global load times • Secure digital-file delivery after successful purchase • Review moderation controls and spam protection • Basic SEO setup so new products index quickly Once finished I’d like a quick start guide or short video showing how to add new digital products, approve reviews and pull simple sales reports. If you have a portfolio piece with similar functionality, drop me the link so I can see it in action.
