I’m building an online store dedicated to ship spare parts and heavy-duty machinery. The site has to let customers register, browse thousands of SKUs with layered filters, chat with an automated assistant for quick help, and check out via bank transfer or UPI/GPay. I’m flexible on the stack—Shopify, WooCommerce, Magento or another robust platform is fine as long as it stays fast under a large catalogue and is simple for my team to manage. Responsive design, clear SEO foundations and an intuitive admin panel for inventory and shipping settings are non-negotiable. Core deliverables • Secure user registration & login tied to order history • Advanced product search with custom filters (part number, brand, vessel type, etc.) • Integrated chatbot that answers FAQs and escalates to support when needed • Checkout flow offering bank transfer instructions plus native UPI/GPay buttons Hand-over is complete when the site is live on my domain, fully tested, and my staff receive a brief walkthrough of day-to-day operations. When you bid, please specify the platform you recommend, how you will handle the search/filter logic, and the timeline you foresee from design mock-ups to launch.
