Missed-Call Lead Recovery — Multi-Tenant SaaS Product

Saved: 2026-07-23
Status: Future Project — Research & Planning
Category: SaaS Product / Revenue
Owner: IT Pro Partner (Sho'Nuff)

Product Concept

A multi-tenant SaaS platform that converts missed phone calls into recovered leads via instant SMS text-back. When a small business misses a call, the system immediately texts the caller from the business's number, logs the lead, and optionally triggers email confirmations, owner alerts, and CRM integration — all before the caller dials the next competitor.

Inspiration: never-miss-a-lead-lite (MIT license) — a single-tenant n8n workflow built by a diesel repair shop owner that catches Twilio missed calls, sends an SMS text-back, and logs to Google Sheets. Proven concept, real-world validated.

Target Customer Outcome

Businesses leave ~62% of calls unanswered (411 Locals study, 2016). Each missed call is a lead that dials the next competitor. This product gives SMBs and agencies a turnkey recovery system so every missed call becomes a logged, texted-back lead within seconds — no technical setup required from the customer.

Ideal customers: SMBs (plumbers, electricians, repair shops, legal, medical), marketing agencies reselling to clients, and vertical SaaS platforms needing embedded lead recovery.

Inspiration Repo vs. Production Architecture

Aspect never-miss-a-lead-lite (LITE) ITPP Production
Tenancy Single business Multi-tenant (isolated per client)
Storage Google Sheets Postgres (schema-per-tenant or tenant-id column)
Workflow Manual n8n import (~20 min setup) Automated provisioning, zero manual setup
Auth None (single-user n8n) API keys + tenant-scoped access via ops portal
A2P/Toll-Free Advisory note in README Managed compliance as a service
Logging Google Sheets row Structured DB with API, analytics, export
Deployment Manual n8n workflow import Containerized, orchestrated, CI/CD
Pricing Free ($0) or $47–97 one-time Recurring SaaS tiers ($49–$299+/mo)
Lead enrichment None Optional: email auto-confirmation, owner alert, CRM push

Key distinction: The inspiration repo is a single-user n8n workflow — excellent proof-of-concept but not a multi-tenant product. ITPP's version is a managed platform where onboarding a new tenant is an automated operation, not a manual 20-minute import.

Core flows:

  1. Customer calls business → unanswered → Twilio webhook fires
  2. n8n receives webhook, looks up tenant by Twilio number
  3. n8n sends SMS text-back from business number (templated message)
  4. Lead logged to Postgres with timestamp, caller number, message, source
  5. Optional: email to lead, SMS alert to owner, push to CRM/webhook

Tenant Isolation & Provisioning

Isolation Model

  • Database: Single Postgres cluster, tenant isolation via tenant_id foreign key on all lead/sms/usage tables. Row-Level Security (RLS) available if tenant-scoped DB users are needed.
  • Twilio: Each tenant gets dedicated Twilio phone number(s). SMS webhooks include the To number, which n8n uses to resolve tenant identity.
  • n8n: Single parameterized workflow (not per-tenant workflow instances). tenant_id derived from incoming Twilio number → DB lookup → all subsequent nodes scoped.
  • Portal: API key authentication, tenant-scoped views (tenant sees only their leads, usage, billing).

Provisioning (New Tenant)

  1. Acquire Twilio number (local or toll-free) via Twilio API
  2. Register A2P 10DLC brand/campaign if 10DLC number; or use verified toll-free
  3. Configure Twilio number webhook → n8n production URL
  4. Insert tenant row in Postgres: tenant_id, business_name, twilio_number, tier, sms_template, created_at
  5. Tenant gets portal login → views leads dashboard immediately
  6. Automation target: Steps 1–5 in a single n8n provisioning workflow or ops portal button

A2P 10DLC / Toll-Free Compliance

US carriers require business SMS registration. Two paths:

Path Requirements Timeline Cost
A2P 10DLC Twilio Brand + Campaign registration, business EIN, website 3–7 days ~$44 one-time brand + ~$1.50–10/mo campaign
Toll-Free Verified Toll-free number + verification submission (use case, opt-in flow, volume estimate) 2–5 days ~$2/mo per number, no campaign fees

ITPP approach: Managed compliance. During tenant onboarding, ITPP handles registration and verification. Compliance status tracked per tenant in Postgres. Non-compliant tenants flagged, SMS blocked until verified.

Opt-out handling: Twilio's built-in STOP/HELP handling left ON for all numbers. No additional opt-out logic needed — Twilio filters at carrier level.

Product Tiers & Suggested Pricing

Tier Price/mo Included Target
Basic $49–79 1 Twilio number, SMS text-back, lead logging, portal dashboard, CSV export, up to 250 leads/mo Solo SMB (plumber, electrician, shop)
Pro $129–199 3 Twilio numbers, Basic + email auto-confirmation, owner SMS alert, urgency routing (3 reply tiers), webhook/Zapier export, up to 1,000 leads/mo, analytics dashboard Growing SMB, small agency (up to 3 clients)
Managed $299+ 10+ Twilio numbers, Pro + agency resell panel, white-label option, priority support, custom SMS templates, CRM integration (Twenty/HubSpot), unlimited leads, SLA Marketing agencies, multi-location businesses

Overage: $0.05/lead above tier limit (Basic/Pro). Twilio SMS/voice usage billed at cost or included margin.

Dependencies

Dependency Status Notes
Twilio account (A2P 10DLC verified) On file Toll-free verification submitted 2026-07-21
n8n (app1) Live n8n.itpropartner.com, Docker on app1
Postgres Live Already on app1 (n8n + LiteLLM databases)
ops.itpropartner.com Live FastAPI on Core, extendable with new endpoints
Domain DNS SiteGround Manual — leads.itpropartner.com or similar would need SiteGround panel entry
Twilio numbers Pending purchase Acquire programmatically or via Console
A2P 10DLC campaigns Pending registration Per-tenant or pooled campaign TBD

Open Questions

  1. Pooled vs. per-tenant A2P 10DLC campaign: Can a single ITPP campaign (with ITPP as brand) cover all tenants, or must each tenant register their own brand? If per-tenant, Managed tier must handle this.
  2. n8n workflow isolation: Parameterized single workflow vs. per-tenant workflow instances. Single is simpler to maintain; per-tenant allows customization but creates sprawl.
  3. Billing integration: Stripe? Manual invoicing? Integrate with ops portal or standalone?
  4. SMS cost passthrough: Bill Twilio usage at cost or include margin? Affects tier pricing.
  5. CRM push destinations: Which CRMs first? Twenty (already on Core), HubSpot, GoHighLevel?
  6. Lead enrichment: Append caller name/location from Twilio Lookup API? Cost per lookup.

Next Steps

  1. Week 1–2: Validate Twilio A2P 10DLC brand registration for IT Pro Partner
  2. Week 2–3: Build single-tenant MVP (one Twilio number → one n8n workflow → Postgres)
  3. Week 3–4: Add tenant model + ops portal dashboard
  4. Week 4–5: Automated provisioning workflow (Twilio number purchase + n8n hookup)
  5. Week 5–6: Beta with 1–2 friendly customers, iterate on SMS templates and routing
  6. Week 7+: Tiers, billing, agency panel, CRM integrations
