SCOPE OF WORK

1. WhatsApp Private Chatbot
— Integrate with 360dialog (WhatsApp Business API)
— Build a conversational intake flow: captures customer name, vehicle make/model/year, part needed, damage description, and photo
— Real-time inventory lookup (reads from Supabase database)
— Replies "out of stock" automatically if part is unavailable
— Directs customers to Shopify product URL for checkout
— Escalates to human agent when bot cannot resolve
— After-hours handling and fallback messages

2. Inventory Middleware Service
— Node.js polling service that syncs Posibolt POS API → Supabase every 5 minutes
— Handles Posibolt auth token refresh and API rate limits
— Writes clean inventory records (SKU, stock qty, price, location) to Supabase
— Error handling so a Posibolt outage does not crash the chatbot
— Deploy to Railway.app

3. Operator Dashboard (Next.js)
— Inventory table: live view, editable stock quantities, add/remove parts
— WhatsApp panel: view active DM conversations, flag escalations
— "Post deal" button: sends a formatted message to WhatsApp group via API
— Shopify order feed via webhook
— Hosted on Vercel

---

REQUIREMENTS
— Strong Node.js (Express or Fastify)
— Next.js for the dashboard
— Supabase (PostgreSQL + real-time)
— REST API integration experience (bonus: Posibolt or similar POS systems)
— WhatsApp Business API experience (360dialog or Twilio preferred)
— You must have built and deployed a chatbot or messaging automation before — please include examples in your proposal
— South Africa-based preferred (same timezone, familiarity with local stack)

PROJECT DETAILS
— Fixed price engagement

— Milestones: chatbot live (week 3), middleware stable (week 4), dashboard complete (week 6)
— All code must be documented and handed over in a private GitHub repo
