Full Messenger & WhatsApp Automation SaaS

I want to build a full Messenger & WhatsApp Automation SaaS with AI-powered chat, multi-tenant architecture, and monetisation features.

The platform should allow each user to have their own bot, connected to their own Facebook Page or WhatsApp number, with separate rules, AI prompts, replies, and database. Bots must never mix data between users.

Key Requirements:

Connect Facebook Page / WhatsApp number

Messenger & WhatsApp integration with Webhooks (real-time messages)

Keyword-based auto replies + welcome messages

AI chatbot with context memory (toggle AI ON/OFF per user, custom system prompt)

User lead capture, tagging, and CSV export

Connect databases (Google Sheet, Airtable, Supabase, MySQL) or allow manual input

Subscription & monetisation system (Free + Paid plans, Stripe integration, usage limits, auto stop when exceeded, trial & coupon support)

Full Admin Panel (user management, plan assignment, usage monitoring, AI control, system logs, analytics, announcements, role-based access)

Deliverables:

Fully functional SaaS system

Source code + deployment instructions

Stripe + Meta API setup (more payment option later)

Documentation for admin and users

Requirements for Freelancer:

Experience with Meta APIs (Messenger & WhatsApp)

Experience building multi-tenant SaaS platforms

AI integration experience (OpenAI API)

Clean, scalable code & good communication
