I run a WhatsApp-based clothing business where I receive 300–1000 customer messages daily. I want to build a fully automated WhatsApp sales system using WhatsApp Business API, AI chatbot, and CRM automation. The system should do the following: 1. Automatically reply to customer messages in natural language (like a sales assistant). 2. Show product categories, prices, and images based on customer queries. 3. Handle common questions like price, size, availability, and delivery automatically. 4. Use AI (ChatGPT/OpenAI integration) to understand free-text customer messages and respond intelligently. 5. Collect customer details (name, address, order info) and store them in a CRM (Google Sheets or Airtable). 6. Automatically identify “hot leads” and transfer them to human agent when needed (final order confirmation). 7. Reduce manual work by at least 70–90%. 8. Provide workflow automation using tools like n8n or Make.com. Preferred tech stack: * WhatsApp API (WATI / Respond.io / Twilio) * AI integration (OpenAI / ChatGPT API) * Automation tool (n8n or Make.com) * CRM (Google Sheets / Airtable) I need a complete end-to-end setup, including workflow design, chatbot logic, AI prompts, and integration setup. Please share your previous experience with WhatsApp automation and AI chatbot systems before applying.
