## 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](https://github.com/leegoldmd-beep/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
