Hi, I’ve reviewed your B2B platform + Merlin ERP integration requirements and can help you build a stable, production-ready system. My approach: • WooCommerce B2B setup with custom pricing, trade accounts, and bulk ordering • Native Merlin SOAP/XML integration (GetStock, SetOrder, SetCustomer) with proper queue handling • Real-time stock + pricing sync with caching for performance • Internal lightweight CRM using WooCommerce + custom tables (no HubSpot/Zoho) • WhatsApp + AI chatbot integration (Twilio + OpenAI GPT) • Flutter mobile app for iOS + Android using shared API layer • Secure API gateway with JWT, role-based access, and logging • Background job system (Redis/BullMQ) for ERP reliability Key focus: • Stable ERP sync (no failed orders or data loss) • Scalable architecture for high-volume wholesale traffic • Clean admin control for pricing, customers, and orders • Mobile-first UX for fast ordering and reordering Timeline: ~8–12 weeks depending on Merlin access readiness Deliverables: • WooCommerce B2B platform fully integrated with Merlin • Flutter mobile app (iOS + Android) • AI + WhatsApp ordering system • Internal CRM + admin dashboard • Full documentation + deployment setup I can start immediately after access is provided. — Rizwan LA

Hi there, We’ve developed multiple B2B platforms with extensive features like product catalogs, order management, and customer management. We also have experience integrating with third-party APIs like Twilio and OpenAI, and we’ve built custom internal CRMs that can serve as a foundation for your project. For your project, we can use a combination of WooCommerce and custom plugins to create a fully optimized solution. This approach allows us to leverage existing features while adding new ones, resulting in a more cost-effective and faster product. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

Hello, This is exactly the kind of build where hidden complexity lives in the integration seams: WooCommerce, Merlin SOAP/XML, Flutter, WhatsApp, and GPT-4 all need to behave like one system, not separate tools. I’ve built PHP/MySQL and WooCommerce solutions with custom CRM tables, API integrations, payment flows, and automation, and I can structure this around reliable Merlin web services, real-time stock/pricing sync, and a clean B2B ordering flow for web and mobile. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I’d first map the Merlin methods, data model, and auth flow, then build the WooCommerce portal, WhatsApp order journey, chatbot logic, and Flutter app in a controlled rollout so each layer stays stable. Could you confirm whether Merlin’s SOAP toolkit includes sample request/response payloads for SetOrder, GetStockMulti, and SetCustomer? Could you confirm whether Merlin’s SOAP toolkit includes sample request/response payloads for SetOrder, GetStockMulti, and SetCustomer? Do you already have the Firebase, Twilio, Stripe, and OpenAI keys ready for integration? How should trade-credit approval and order status sync behave when Merlin is temporarily unavailable? Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

Hi, I had a chance to review your project and it looks interesting. Rather than sending a generic proposal or making assumptions based only on the description, I prefer to first understand the specific goals, constraints, and expectations behind the project. In many cases, the actual challenge is not the development itself but ensuring the solution fits the workflow and scales properly as the project grows. I'd be interested in discussing a few details and sharing some initial observations after learning more about your requirements. Thanks for your time. Shiv,

One suggestion is to enhance user experience by incorporating a seamless AI Chatbot feature for customer interactions. I've worked on similar projects where I successfully integrated eCommerce platforms with backend services to streamline order processes. I can complete this within the estimated 45-50 days. Quick question: What is the expected volume of orders you anticipate handling on the platform? Regards, Khurshid Ahmed

@codefusion53

Hi, I’m excited about the chance to develop your comprehensive B2B wholesale ordering platform integrating WooCommerce, Merlin ERP, Flutter mobile app, and GPT-4 AI chatbot.

For the mobile app, I’ll deliver a polished cross-platform Flutter solution with Firebase push notifications and JWT authentication matching the website’s functionality. The AI chatbot implementation on both web and WhatsApp using OpenAI GPT-4 will enhance customer engagement and automate support. I appreciate the clear timeline and budget; I can commit to delivering quality within 45-50 days and $700-800 budget. I’m ready to start as soon as Merlin access and API keys are provided and will ensure thorough testing and documentation for smooth handover.

I can work with Merlin datasource access, company/depot configuration, and API setup. Estimated timeline: 45–50 days depending on Merlin access and API credentials. Looking forward to discussing milestones and execution. Best regards
