I’m launching “nexs”, an online store that will sell downloadable digital products. I already have the brand name; what I need now is a full-featured e-commerce website that makes purchasing and instant file delivery effortless for customers on both desktop and mobile. The build should include a clean, modern storefront, secure checkout with major payment gateways, automated delivery links after payment, and an easy-to-use admin panel so I can upload new files and track sales without touching code. I’m open to the framework or CMS you prefer (Shopify, WooCommerce, custom Laravel, etc.) as long as it remains lightweight and scalable. Please bring experience with responsive design, digital-product licensing or download management plugins, basic SEO setup, and the usual security best practices. Let me know which stack you recommend, a realistic completion timeline, and a few examples of similar digital-only shops you’ve built.
