We need a freelance developer to build a WhatsApp-native appointment booking system for beauty salons and hairdressers. Customers book entirely by chatting to the salon's WhatsApp number — choosing a service, day and time, with the bot checking real-time availability and confirming only genuine open slots (no double-bookings). Salons manage everything — hours, staff, services, and bookings — from a simple web dashboard, and get notified instantly when a booking lands. The stack is WhatsApp Business Cloud API (direct with Meta, no reseller), n8n for the automation/backend logic, and PostgreSQL for the database, all self-hosted on free-tier cloud infrastructure — full technical spec is attached. The build must be multi-tenant from day one (so adding salon #2, #10, #50 is a config step, not a rebuild) and must have no recurring platform or licence costs — the only possible ongoing cost is Meta's own small per-message rate on optional reminders. We're looking for a fixed-price quote for the pilot build, plus your suggested rate for onboarding each additional salon afterward. Please share relevant n8n/WhatsApp API experience and a rough phased timeline with your application.

The real challenge in your build is not the chat flow itself, it’s preventing false availability while keeping the system multi-tenant from day one and free of recurring software costs. I’d structure the pilot around a solid tenant-aware database schema, booking conflict checks, and clean n8n workflow orchestration so each salon can be added by configuration rather than fresh development. This is the kind of job where direct WhatsApp Cloud API experience matters because template handling, session logic, and webhook events need to behave predictably once real users start booking. I’ve handled automation projects where the success of the system depended on dependable state management between messaging, backend logic, and admin controls rather than just building a nice front end. A few details would help me map the pilot scope correctly: - For the dashboard, do you need separate salon-owner and staff roles, or just one admin role in the first release? - Should availability be generated from working hours only, or also from manual blackout dates and breaks? - What level of onboarding setup do you expect per added salon after the pilot goes live?

Hi there, I can see the real challenge here isn’t just taking bookings , it’s making WhatsApp feel like a reliable front desk that never double-books and still stays easy for each salon to manage. I’ve built business systems around PHP, API integrations, automation, and booking logic, and I can help shape this into a clean multi-tenant flow with WhatsApp Business Cloud API, n8n, and PostgreSQL. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. My focus would be on availability checks, salon-specific configuration, dashboard controls for hours/services/staff, and a self-hosted setup that keeps recurring costs minimal. If you’d like, I can map the pilot into clear phases: core chatbot flow, booking engine, dashboard/admin layer, then multi-tenant onboarding. Could you please clarify whether staff availability should be managed as fixed schedules, rotating shifts, or both? Best regards, Asad

Hi, Self-hosting this on free-tier cloud infrastructure means managing connection pooling tightly on PostgreSQL so peak weekend booking surges never exhaust the database handles. I will configure persistent connection reuse directly inside the n8n webhook nodes to keep memory consumption well within tight resource limits. Building multi-tenant architecture with zero recurring licensing costs is my daily bread, and I will structure the PostgreSQL schema with strict tenant isolation from day one. My plan is to spin up the Meta Cloud API webhooks, map the conversation state machine in n8n, and build the staff management dashboard. I will deliver the entire pilot build in 1 day for $132, which includes the complete database migration scripts, n8n workflow templates, and WhatsApp message templates. Shall we confirm the Meta Business verification status before I initialize the database schema?

A WhatsApp-only salon booking flow sounds simple on the surface, but the hard part is making slot checks truly reliable across staff calendars so bookings never collide and tenant #2 or #50 does not force a rebuild. I’d approach this by designing the tenancy, availability rules, and booking lock logic first, then wiring the WhatsApp Cloud API, n8n workflows, and PostgreSQL structure around that. I’ve worked on automation-heavy builds where messaging, workflow logic, and database state all have to stay in sync, which is exactly what this needs. The key here is not just getting messages to send, but making the booking confirmations dependable and the dashboard easy enough that a salon owner can manage hours, staff, and services without technical help. To price this properly, I’d like to confirm a few points first: - Is the web dashboard expected as a lightweight admin panel only, or do you also want reporting and customer history in phase 1? - In the pilot, should reminders, cancellations, and reschedules be included or kept for phase 2? - Does the attached spec already define how staff-specific availability and service duration buffers should work?

Hi, I've built messaging-driven booking flows before, including a web app that handled appointment and SMS confirmations through Twilio with a REST API and third party integrations. LAMP-SMS-Twilio-App: strong 5 star review, "will hire again" The part that decides this build is the availability check. To guarantee no double-bookings across staff and services, I'd hold the slot at read time and confirm against a single Postgres transaction, so two people chatting at once can't grab the same slot. n8n handles the WhatsApp Cloud API flow, Postgres stays the source of truth. Multi-tenant means a salon_id on every table and every workflow branch from day one. One question: does each salon bring its own Meta WhatsApp number, or do you want a shared number with routing?

Howdy, A WhatsApp booking system is only as reliable as its availability and booking logic, so the bot should never confirm a slot unless it has verified live PostgreSQL availability and locked the booking against double bookings across salons, staff, and services. I can build the n8n workflow around Meta’s WhatsApp Business Cloud API, integrated directly with PostgreSQL, and include a simple multi tenant dashboard where new salons can be added through configuration rather than requiring changes to the core system. I’ll also structure the pilot into clear phases covering the complete booking flow, database and multi tenancy, dashboard, notifications, and deployment, making it easier to test and scale. I can show you similar automation examples in chat. If you share the attached technical spec, I can review the requirements in detail and provide a fixed pilot quote, additional salon onboarding rate, and a realistic phased timeline based on the actual scope.

Hello, We understand you need a WhatsApp-native booking bot where salon customers chat to book services, the bot checks real-time availability, avoids double-booking, and confirms slots. Salon owners manage services, staff, hours and view bookings via a simple web dashboard, receiving instant notifications for new bookings. The system must be multi-tenant from day one, run on WhatsApp Business Cloud API with n8n handling automation, and use PostgreSQL on a free-tier self-hosted cloud, with only Meta message costs for optional reminders. Technical approach: - Multi-tenant PostgreSQL (shared schema with tenant_id) lets us add salons by config only. - WhatsApp webhook → n8n workflow parses inbound messages, validates service/day/time, queries availability, sends template confirmations. - n8n PostgreSQL nodes handle CRUD; custom JS resolves slot conflicts. - Admin dashboard (React) calls a lightweight Node/Express API for salon-specific data. - Deployment via Docker-compose on a free-tier VPS (Oracle Cloud Free Tier) with SSL. Core modules: 1. WhatsApp listener & parser (n8n). 2. Availability engine (slot generation, booking, cancellation). 3. Tenant management API (CRUD for salons, staff, services, hours). 4. Admin dashboard (React) for calendar view and config. 5. Notification service (template messages). Relevant systems: - AI-Powered Slack Clarification Assistant (n8n + OpenAI) - complex multi-step workflow with external APIs. - Automation Lead Generator - 8-Agent n8n pipeline for data enrichment and outreach. - AI-Powered Chatbot Backend - n8n workflow with intent detection and real-time API calls. Implementation strategy: - Week 1: shared infra (Docker, PostgreSQL, n8n) + tenant schema. - Week 2: WhatsApp-n8n listener, availability logic, basic confirmations. - Week 3: tenant API + admin dashboard MVP. - Week 4: multi-tenant testing, reminder template, performance tuning. - Week 5: pilot handover, onboarding process for additional salons (config only). Questions: 1. Expected peak concurrent conversations per salon to size n8n worker concurrency? 2. Preferred WhatsApp message templates for confirmation/reminders, or should we propose standards? 3. Admin dashboard - same sub-domain as API or separate domain per salon? Regards, Rohit

What will make or break this salon system is the booking engine underneath the WhatsApp chat — if the availability logic is weak, double-bookings and messy staff scheduling will show up fast. My first step would be to lock down the tenant model, appointment rules, and real-time slot validation, then build the WhatsApp and n8n layers on top of that foundation. I’ve worked on workflow-driven setups where automation has to do more than send messages — it has to make decisions from live data, update records correctly, and trigger the right notifications instantly. For your pilot, that matters more than flashy presentation because salon owners will judge the system by whether bookings are accurate and easy to manage. I can also suggest a practical per-salon onboarding structure once I see the exact spec. Before that, can you clarify: - Is the dashboard part already specced as custom UI, or are you open to a lean admin interface for the pilot? - Should each salon have isolated staff/services settings plus its own WhatsApp number from the start? - Are reminder messages optional in v1, with only new-booking notifications required immediately?
