I want to turn my current inventory of pre-owned vehicles into a fully interactive WhatsApp Business catalog. The core objective is to let prospects browse every car, tap for details, pay instantly, and receive an automatic confirmation right inside the same chat. Scope of work • Set up the WhatsApp Business API (or Cloud API) under my Facebook Business Manager. • Build the catalog so each listing shows: – Price and all available payment options – Full technical specifications (mileage, model year, engine, features, etc.) – Verified customer reviews – Any running offers or discounts I can toggle on/off • Integrate a payment gateway with webhooks for real-time status updates. I’m open to PayPal, Stripe, Square or your recommended alternative as long as it supports one-click checkout in our market. • Configure automatic, templated messages that confirm payment the moment a transaction clears, and push the order details to both the buyer and my sales dashboard. • Provide a simple admin panel (web or mobile) where I can add/edit cars, attach photos, and activate promotions without touching code. Tech preference I’m comfortable if you use Node.js, Python or PHP for the backend, MySQL or Firestore for data, and webhook-driven automation via Twilio or Meta’s native endpoints—feel free to suggest the most stable stack. Deliverables 1. Live, approved WhatsApp Business catalog linked to my verified number 2. Payment gateway integration with automatic confirmation flow fully tested 3. Admin interface with documentation and a short hand-over session The project is complete when a customer can discover a car, pay securely, and see an instant confirmation message, all within WhatsApp.
