About OmniFlow — Turnkey Multi-Tenant AI Booking SaaS & WhatsApp Agent (Flutter Web/iOS/Android + Supabase + n8n)
Multi-Tenant AI Booking SaaS & WhatsApp Agent (Web & App)
OmniFlow is an enterprise-grade, multi-tenant AI booking and business management platform designed for appointment-based service industries (Barbershops, Salons, Pet Shops & Vet Clinics, Healthcare Clinics, and Studios). Unlike basic single-page scripts, OmniFlow is a complete full-stack ecosystem featuring a native Flutter 3.x frontend (Web PWA, iOS, and Android), a robust Supabase PostgreSQL multi-tenant backend with Row-Level Security (RLS), and an autonomous LangChain-powered n8n WhatsApp AI Agent connected to OpenAI GPT-4o, Whisper audio voice notes transcription, and Redis buffer control. 💎 Key Highlights & Commercial Value: 1. True Cross-Platform (Single Codebase): Built in Flutter 3.x. One single codebase compiles directly to responsive Web (PWA), Android (APK/AAB), and iOS (IPA). 2. Autonomous WhatsApp AI Agent (n8n + GPT-4o): Handles real-time conversational booking, dynamic slot checking in PostgreSQL, audio voice notes transcription via Whisper, pet/client intake questionnaires, automated 2-hour appointment reminders, and intelligent human handoff. 3. Multi-Tenant with Row-Level Security (RLS): Over 15 enterprise database migrations ensuring strict tenant data isolation. 4. Trilingual & Global Market Ready: Native, instant language switching between English (default), Portuguese, and Spanish. 5. Pre-configured Vertical Panels: Dedicated modules for Barbershops (multi-staff calendars), Pet Shops (pet profiles, breeds, coats), Healthcare Clinics, and a SaaS Master Admin overview (MRR, tenant monitoring). 📦 What's Included in the Delivery: Complete Flutter 3.x Frontend Source Code (Web PWA, Android, and iOS configurations). Supabase Database Schema: 15+ automated SQL migrations (000 to 099) with full RLS policies and stored procedures. Sanitized n8n AI Agent Workflow: Ready to import into your n8n workspace with OpenAI and Evolution API. Commercial White-Label Agency License: Rights to rebrand, customize logos/colors, and deploy for unlimited sub-clients with 0% royalties. Comprehensive 40+ Page Setup Guide (PDF & HTML): Complete step-by-step onboarding manual in English, Portuguese, and Spanish. 🛠️ Technical Onboarding & Support Policy: Self-Hosted Architecture: The buyer connects their own Supabase, OpenAI, and Evolution API instances. Detailed Documentation: The included trilingual PDF manual covers the exact sequence for database migrations, n8n imports, WhatsApp QR-code linking, and branding changes.

Reason for selling
As a specialized software engineer, my passion lies in architecting complex multi-tenant database systems, AI pipelines, and cross-platform frontends from scratch. Commercializing enterprise SaaS and running local B2B agency sales campaigns requires a dedicated go-to-market focus. I am passing this production-ready platform to an ambitious agency owner or SaaS operator who can scale it to its full commercial potential.
