Digital Product E-commerce Website

I’m ready to launch an online store that sells downloadable items, and I need a full-featured e-commerce website built from the ground up. The focus is exclusively on digital products, so I want a smooth buying experience that ends with an instant, secure file delivery to the customer’s inbox or account area.

Core requirements
• Shopping cart, product pages, and checkout tailored for digital goods (no shipping fields).
• Payment gateway integration for Credit/Debit Cards and PayPal, with automatic order confirmation and download link generation.
• Clean, responsive design that looks great on desktop and mobile.
• Simple back-office where I can upload files, set prices, create discount codes, and view sales reports.
• Basic SEO setup so the store is discoverable from day one, plus a privacy-policy and terms page to cover digital sales.

Acceptance criteria
1. I can add a new digital product, publish it, and complete a test purchase using both payment options.
2. The buyer receives a working download link immediately after payment.
3. No personally identifiable card data is stored on the site; everything routes through the chosen gateways’ secure APIs.
4. Page speed scores stay in the green on Google PageSpeed Insights.

I’m open to the stack you feel most efficient with—WooCommerce, Shopify, or a lightweight framework—provided it meets the above criteria and is easy for me to maintain afterward. Let’s discuss your timeline, milestones, and any portfolio examples of similar digital-only stores you’ve delivered.
