Hi there, I’ve read your OpenCart/PrestaShop/WooCommerce customization brief and I’m confident I can deliver a robust, upgrade-friendly plugin that lets your B2B customers freely select and mix parts, with a live preview, real-time price updates, and a generated BOM for production, all without touching core systems. Asad - I understand a factory-level spare-parts configurator must be precise, scalable, and multilingual. With 15+ years in PHP, WooCommerce, and multi-channel eCommerce, I’ve built plugin-based solutions that preserve upgrade paths while adding complex rules, pricing logic, and exportable BOMs. What I’ll do: implement a standalone plugin that adds a parts-configurator widget with dynamic spec switching, live pricing, and a reversible front-end that doesn’t touch core files; backend admin rules for incompatible parts, combo limits, multi-language (EN/CN) and multi-currency support; exportable BOM in a machine-friendly format (CSV/Excel) aligned to factory production; PayPal integration; fully responsive UI; and clear developer docs plus a one-month bug warranty. I’ve shared an initial estimate based on your description, and once we go over a few technical details, I’ll confirm the exact cost and delivery schedule. Could you share the exact list of core parts and their incompatibility rules, plus any preferred BOM format and language/currency lists to start the architecture? Best regards, Asad

You need a powerful yet flexible product configurator for your B2B website, but off-the-shelf solutions never handle custom part rules, live pricing, and factory-ready BOM exports without constant headaches and manual fixes. With my plugin-only approach, you get a smooth DIY assembly experience for your customers and a backend that keeps your site upgradeable and your production team happy. First, I’ll develop a responsive frontend where customers can pick and combine parts, see instant previews, and watch live price updates. Next, I’ll set up your backend so you control part compatibility, combo limits, and multi-language options, all without touching the core. Finally, I’ll ensure every order auto-generates an accurate, exportable BOM, with full documentation and a short warranty for peace of mind. Could you share which platform you prefer out of OpenCart, PrestaShop, or WooCommerce?

Hi, As per my understanding: You need a custom plugin-based DIY product configurator for your B2B spare parts website that allows customers to freely combine compatible parts, switch specifications, preview configurations live, and see automatic price updates in real time. The system must also generate BOM lists for factory production while remaining fully upgrade-safe without modifying the OpenCart, PrestaShop, or WooCommerce core. Implementation approach: I will develop the configurator as a standalone plugin/module compatible with your selected platform while keeping the core system untouched for future upgrades. On the frontend, customers will be able to select components dynamically with realtime validation, live pricing, spec switching, and responsive product previews optimized for both desktop and mobile devices. On the backend, I will implement compatibility rules, combination limits, BOM generation, multilingual and multi-currency support, and PayPal integration. The generated orders will automatically include exportable BOM data suitable for factory production workflows. The plugin code will remain modular, documented, and easy to maintain, with installation/setup guides and a post-delivery bug support period included. A few quick questions: 1. Which platform are you currently using: OpenCart, PrestaShop, or WooCommerce? 2. Do you already have structured compatibility/BOM rules prepared?

Hi there! I understand you need a clean, clinical-style Wix website for a chiropractic clinic, not a spa or wellness design. Most clinic websites lose trust when they look too decorative or unclear for patients. I have strong experience in Wix website design and template customization for service-based and professional businesses. I have worked on structured websites where clarity, patient-friendly navigation, and professional medical presentation were important. I also have experience with SEO basics and accessibility-focused design for better usability and compliance. My approach will start with reviewing your selected template and understanding your exact structure. I will customize the layout to give a proper clinical and professional medical look. I will make sure the website is fully mobile responsive with smooth and simple navigation. I will also apply basic SEO and ADA-friendly setup like headings, contrast, and alt text for better performance. check our work https://www.freelancer.com/u/ayesha86664 Do you want the homepage to focus more on services or patient pain points first? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

Hey there, plugin layer handles UI selection, backend rule matrix controls valid combinations, pricing engine recalculates totals on every change, and final order is converted into a structured BOM for factory production export, fully multilingual and currency ready. 150 dollar budget is only enough for a basic MVP, not full industrial grade system, scope must be controlled or phased. Question: do you want a strict MVP version or a scalable production ready architecture plan? Inbox me ASAP Warm regards, Umer Kayani
