I need a full-featured online store built from the ground up. The site will sell physical products, so it must handle product catalogues, secure checkout, inventory tracking, and customer accounts while remaining fast and mobile-friendly. Platform I have not committed to a specific platform yet, so the build could be on Shopify, WooCommerce, or Magento—whichever you can justify as the best long-term fit in terms of scalability, cost, and ease of maintenance. Core requirements • Clean, modern UI that reflects a professional retail brand • Responsive design that works flawlessly on phones, tablets, and desktops • Simple product and category management in the back-office • Multiple payment gateways (credit/debit cards at minimum, plus PayPal or Stripe) • Automated order confirmation emails and basic marketing hooks (newsletter opt-in, coupon codes) • SEO-friendly structure and fast page load times • Basic on-page security hardening (SSL, bots/Spam protection) Acceptance criteria 1. Store launches on a live domain without critical errors. 2. All core e-commerce flows—browse, add to cart, checkout, payment, order confirmation—function end-to-end. 3. Admin dashboard allows me to add/edit products, prices, and images with no coding knowledge required. 4. Site passes Google Mobile-Friendly Test and achieves <3 s load time on PageSpeed Insights for key pages. 5. Clear, written handover guide (or brief video) showing routine tasks such as processing orders and updating content. Once these boxes are ticked, the project is complete and we can discuss any future feature upgrades or maintenance packages you may suggest.
