I have an existing website and am ready to turn it into a fully-functional online store that sells our line of physical goods. The core of the job is to add a seamless product catalog, shopping cart and secure checkout while keeping the current look and feel of the site. Payments: I need credit and debit card processing in place on day one and a direct bank-transfer option at checkout. The build should be flexible enough that I can plug in PayPal later if I choose, without a full re-work. Shipping: All orders must pull real-time rates and labels from the major carriers—UPS, FedEx and DHL—so customers see accurate costs and tracking numbers automatically populate in their account area and in the admin dashboard. Feel free to suggest the most suitable stack (for example WooCommerce, Shopify, Magento, or a lightweight headless approach). Whichever route we take must support our current hosting setup or include a clear migration path. Deliverables • Fully integrated ecommerce module on my existing domain • Product catalog template I can duplicate for new items • Gateway configuration for cards and bank transfers, tested in both sandbox and live modes • Carrier API hookup for UPS, FedEx and DHL with label generation and tracking updates • Basic documentation that shows me how to add products, run promotions and view orders Acceptance criteria: the store processes a live $1 test transaction on both payment methods, returns accurate shipping quotes to three sample addresses, and sends automated order-confirmation emails that land in an inbox (not spam). If this scope is clear, let’s talk timeline and choose the tech that fits best.
