SNØ Technical Business Plan: Automated Client Re-Engagement for Med Spa & Aesthetic Clinics

1. Overview

SNØ automates re-engagement of previous clients for US Med Spa and Aesthetic Clinics, targeting those with 500+ contacts and treatments averaging >$1,000. The platform uses n8n (self-hosted on Hetzner) to orchestrate: - SMS: 5–10 personalized messages per client via SMS8 (Android phones) or Telnyx. - AI Voice: Resemble AI (self-hosted) with local RAG (FAISS + GPT-4o), Whisper (ASR), and Rasa (NLU) for low-latency sales closing. - Gift Cards: $50 non-refundable deposit via Stripe (Apple Pay/Google Pay/credit cards), with QR codes delivered via Apple Wallet/Google Wallet, encoding treatment prices. - Commission: 30% of treatment cost (e.g., $600 on $2,000) collected via Stripe Connect invoices post-visit. - Onboarding: Clinics join via OpnForm waitlist, sync CRM data (Mindbody, Zenoti, Vagaro, AestheticsPro), and connect systems (Leadsie, Entri). - Advertising: Meta ads acquire waitlist sign-ups at $5–$10 each.

The system handles 500,000 SMS across 100+ clinics, ensuring scalability, compliance (TCPA/CCPA), and ease for non-technical clinics.

2. Objectives

• Process 500,000 SMS (100 clinics × 5,000 SMS) and thousands of AI voice calls monthly.
• Sync CRM data in real-time for 99% of US med spa CRMs.
• Ensure low-latency AI voice with local RAG/Whisper/Rasa (<500ms response time).
• Guarantee 30% commission collection via QR code scanning and Stripe Connect.
• Acquire waitlist sign-ups cost-effectively via Meta ads.

4. SMS Provider Comparison (500,000 SMS)

| Provider | Price per SMS | Cost for 500,000 SMS | Pros | Cons | n8n Integration | | --- | --- | --- | --- | --- | --- | | Twilio | $0.0079 | $3,950 | Robust APIs, TCPA compliance | High cost, A2P 10DLC complexity | Native Twilio node | | Telnyx | $0.004 | $2,000 | Cheaper, low-latency voice | Setup complexity | HTTP Request node | | SMS8 (Android) | ~$40/phone/month | $400 (10 phones) | Lowest cost, uses unlimited plans | Manual phone management, carrier caps | Webhook/HTTP Request node |

5. Operational Logic

5.1 Waitlist & Onboarding

• Waitlist (OpnForm):
• Fields: Clinic name, contact name, email, phone, Instagram handle, treatments, capacity (>50 bookings), average spend (>$1,000), client count (>500), referral details, treatment price list.
• Hosted on Hetzner; data stored in MongoDB.
• n8n validates submissions, approves clinics meeting criteria.
• Onboarding:
• Social Media: Leadsie API authorizes social@sno.io for Meta, Google, Shopify, WordPress.
• Domain: Entri API configures DNS; manual TXT records for unsupported providers.
• CRM Sync:
  • Mindbody: API (/client/clients) for real-time name, phone, treatment history.
  • Zenoti: API (/v1/customers) for client data.
  • Vagaro: API (/clients) for real-time export.
  • AestheticsPro: API (/clients/export) or CSV (Reports > Client List).
  • Fallback: OpnForm CSV upload, validated by n8n.
• Price List: Clinics submit treatment prices (e.g., “Injectables: $2,000”) via OpnForm, stored in MongoDB.
• Agreement: Clinics sign contract (via OpnForm/DocuSign) for 30% commission payment.

5.2 Outreach

• SMS (SMS8/Telnyx):
• n8n generates 5–10 personalized SMS using GPT-4o (e.g., “Hi Jane, how was your Injectables at [Clinic]? Ready for a refresh?”).
• Random delays (30–120s) simulate human texting.
• Sent via SMS8 (webhook/HTTP) or Telnyx (HTTP).
• TCPA compliance: “Reply STOP to opt out.”
• AI Voice (Resemble AI):
• Triggered after 3–5 SMS with no booking to close sales.
• RAG: FAISS indexes client data (e.g., “Jane: Injectables, 2024-03-15”); GPT-4o injects common responses (e.g., “Interested in booking?”) in <500ms.
• ASR: Whisper transcribes client speech (~300ms latency).
• NLU: Rasa detects intents (e.g., “interested,” “not now”) and manages dialogue; Riva as fallback.
• Natural pauses (1–2s) ensure human-like calls.
• Gift Card:
• Client selects treatment via SMS/voice (e.g., “Injectables, $2,000”).
• n8n generates Stripe Payment Link ($50, supports Apple Pay/Google Pay/credit cards).
• Post-payment, n8n creates QR code (QRCode Monkey) encoding:
  • Gift card ID (e.g., GC-12345).
  • Treatment ID (e.g., INJ-01).
  • Price (e.g., $2,000).
  • Client ID.
  • Digital signature (HMAC-SHA256).
• QR code delivered via Apple Wallet (Passkit API) or Google Wallet (Google Pay Passes API).
• Booking & Commission:
• Client presents QR code at visit; clinic scans using SNØ web app (React, hosted on Hetzner).
• Web app verifies signature, displays treatment/price, and allows price adjustment if needed.
• Client pays clinic full price (e.g., $2,000).
• n8n logs scan in MongoDB, issues Stripe Connect invoice for 30% ($600).
• Stripe Connect auto-debits clinic’s account if unpaid after 7 days.

5.3 Commission Collection Setup

• Clinic Agreement:
• Signed via OpnForm during onboarding, stipulating:
  • 30% commission on treatment price.
  • Payment within 7 days of invoice.
  • Penalties for non-payment (e.g., SNØ suspension).
  • Audit rights for SNØ to verify bookings.
• Stored in MongoDB, linked to clinic ID.
• QR Code Scanning:
• SNØ web app (React) or third-party QR scanner redirects to https://sno.io/verify/GC-12345.
• n8n validates signature, retrieves treatment/price from MongoDB.
• Clinic confirms/adjusts price (e.g., if client chose $1,500 treatment).
• Scan logged with timestamp, clinic ID, and price.
• Invoicing:
• n8n triggers Stripe Connect invoice post-scan (e.g., $600).
• Clinics onboard with Stripe Connect, linking bank/card for auto-debit.
• Invoices visible in SNØ web app’s clinic dashboard.
• Safeguards:
• Digital signatures prevent QR tampering.
• Real-time CRM syncing cross-checks booking data.
• Flagged discrepancies (e.g., frequent price adjustments) trigger manual review.
• Incentives (e.g., 25% commission for 48-hour payment) encourage compliance.
