I need a clean, modern-looking e-commerce site that showcases my physical products and lets customers add products to their cart and at checkout page customer must be able to fill their information to place the order, once order is placed a GST quotation must be sent to customer from whatsapp. As soon as they hit “Request Quote”, the site should automatically generate a PDF quotation or pro-forma invoice and push it to the customer through my mobile number (SMS, WhatsApp, or a similar gateway you recommend). Because I already handle stock control and invoicing elsewhere, the site itself doesn’t need a full inventory or billing module, but it must stay in sync with my existing billing software. A two-way API connection that pulls product data and pushes confirmed orders back to the software will keep everything tidy without duplicate entry. I prefer a fully custom build rather than Shopify or WooCommerce, so you’re free to pick the stack that delivers fast page loads, rock-solid security, and an easy-to-use admin panel. The look and feel must lean toward modern minimalism: generous white space, crisp typography, mobile-first layout, and no visual clutter. Core deliverables • Responsive front-end with modern, minimalist UI • Product catalogue and “Request Quote” flow • Automated PDF quotation/PI generator • Messaging gateway integration tied to my mobile number • API bridge to my billing software for product sync and order hand-off • Basic CMS/admin area to add or edit products and track quote status • Deployment, brief staff handover, and post-launch bug fix window I’ll provide branding assets, sample product data, and API docs for the billing platform as soon as we start.
