Global Digital Product E-Commerce Site

I’m ready to launch a fully-functional website that lets customers anywhere in the world purchase and instantly download my digital products. The core goal is straightforward: a clean, secure online store where visitors can browse, pay, and receive their files without friction on desktop or mobile.

Here’s what matters most to me:
• A reliable e-commerce platform (Shopify, WooCommerce, or another proven solution) configured for digital goods—no shipping logic needed, just automated file delivery.
• Multiple payment gateways so buyers from different regions can check out in their preferred currency.
• Clear product pages with secure download links that activate only after successful payment.
• Responsive design that looks sharp on phones, tablets, and desktops.
• Basic SEO settings in place so the store can start ranking as soon as it goes live.

I’ll supply all product files and copy; I need you to handle setup, theme customization, and any plug-ins or apps required to manage downloads and customer accounts. Once complete, please show me how to add new products and track sales so I can run the store independently.

If you have experience launching global-ready digital storefronts, I’d love to see examples and discuss the best platform for this project.
