RouteCast - Automated Delivery ETA SMS Bot for Local Independent Couriers and Meal Prep Services

Independent couriers and meal prep delivery operations send ETA texts manually from their personal phones — hundreds of them per week. RouteCast auto-sends personalized SMS updates from a business number as drivers move through a stop list, no app download required for customers.

What is it?

Local couriers, meal prep delivery services, and small fleets have no dispatch software that fits a $300/month budget and actually works for a 2-person operation. RouteCast is a web app where the driver or dispatcher inputs today's stop list, marks stops as en-route or completed, and the system auto-fires an SMS to the next customer with a real ETA based on average stop duration. Customers reply STOP to opt out — fully TCPA-compliant. No customer app download required. Built with Twilio SMS, a simple Next.js dashboard, and Supabase for stop and route state. Viable for any independent courier, weekly meal prep box, or last-mile florist.

Why now?

Twilio SMS pricing dropped significantly and Supabase realtime makes stop-state sync trivial in April 2026 — this took a dedicated backend engineer 3 months to build in 2021 and now ships in a week with Cursor.

▸Stop list builder where dispatcher enters customer name, phone, and address for the day.
▸Auto-SMS fires to the next customer when current stop is marked complete with ETA based on average stop time.
▸TCPA-compliant STOP opt-out handling via Twilio inbound webhook.
▸Dispatcher dashboard showing live stop status, SMS delivery receipts, and completion rate.

Target Audience

Independent local couriers, meal prep delivery operators, and small fleet dispatchers — roughly 200k small delivery operations in the US alone.

Example Use Case

Jordan runs a weekly meal prep delivery business with 80 customers per week, uses RouteCast to fire ETAs automatically as he completes each stop, eliminates 40 manual texts per day, and gets zero missed-delivery complaints for the first time.

User Stories

▸As a meal prep delivery operator, I want my customers to receive an ETA text automatically when I finish the previous stop, so that I stop sending 60 manual texts every delivery day.
▸As a dispatcher, I want to see SMS delivery receipts for every customer in real time, so that I know who did not get the message and can call them manually.
▸As a customer on the receiving end, I want to reply STOP to never receive these texts again, so that I have control over my communication preferences.

Done When

✓Stop list: done when dispatcher can add 10 stops with name and phone and reorder them by drag-and-drop before route starts
✓Auto-SMS: done when marking a stop complete triggers an SMS to the next customer within 10 seconds with the correct ETA in the message body
✓Opt-out: done when a customer texts STOP and their number disappears from future SMS sends immediately and permanently
✓Dashboard: done when delivery receipts show green checkmarks for delivered and red for failed within 30 seconds of Twilio callback.

What's the roadmap?

Feature Roadmap

V1 (launch): stop list, auto-SMS ETA, opt-out handling, Stripe billing. V2 (month 2-3): customer-facing live tracking page, multi-day route history. V3 (month 4+): multi-driver dispatch, route optimization integration.

Milestone Plan

Phase 1 (Week 1): full stop-to-SMS flow ships and tested with real Twilio number. Phase 2 (Week 2): Stripe billing live, 5 operator beta users firing real routes. Phase 3 (Month 2): 20 paid operators, Facebook group marketing running.

How do you build it?

Tech Stack

Next.js, Twilio SMS API, Supabase, Stripe, Resend — build with Lovable for dashboard UI, Cursor for Twilio webhook logic.

Suggested Frameworks

Next.js, Twilio Node SDK, Supabase

Time to Ship

1 week

Required Skills

Twilio SMS API, Next.js API routes, basic Supabase queries.

Resources

Twilio docs, Supabase quickstart, Next.js docs.

MVP Scope

app/page.tsx (landing), app/dashboard/page.tsx (stop list + status board), app/api/stops/route.ts (CRUD for stops), app/api/sms/send/route.ts (Twilio SMS trigger), app/api/sms/inbound/route.ts (STOP opt-out handler), lib/twilio.ts (Twilio wrapper), lib/eta.ts (average stop duration calculator), lib/db/schema.ts (Drizzle schema), .env.example, seed.ts (demo stop list).

Core User Journey

Create stop list -> start route -> mark stop complete -> system fires ETA SMS to next customer automatically -> view delivery receipts on dashboard.

Architecture Pattern

Dispatcher marks stop complete -> Supabase updates stop status -> Next.js API computes next ETA -> Twilio sends SMS to next customer -> inbound STOP reply triggers opt-out write to Supabase -> dashboard reflects delivery receipt.

Data Model

Operator has many Routes. Route has many Stops. Stop has one Customer (name, phone), one status (pending/en-route/complete), one SMSLog. Operator has one OptOutList.

Integration Points

Twilio SMS API for outbound ETA texts and inbound STOP handling, Supabase for stop state and opt-out list, Stripe for billing and usage metering.

V1 Scope Boundaries

V1 excludes: GPS driver tracking, multi-driver dispatch, route optimization, customer-facing tracking page, mobile app.

Success Definition

A meal prep operator the founder never spoke to signs up, builds their first stop list, fires real ETAs to 20 customers, and upgrades to paid before the 50-SMS trial expires.

Challenges

TCPA compliance for SMS marketing is a real legal risk if the tool is misused for promotional messages — must enforce transactional-only SMS framing in onboarding and terms. The hardest non-technical problem is finding the first 10 operators — they are not on ProductHunt.

Avoid These Pitfalls

Do not allow operators to send promotional SMS through the tool — TCPA fines are real and can hit $500 per violation. Do not try to build GPS tracking in v1 — ETA via average stop time is good enough and ships in a day. Finding first operators in Facebook groups takes 3x longer than the build — post before writing code.

Security Requirements

Supabase Auth with email/password, RLS scoping stops and SMS logs to operator only, rate limit SMS send API to 60 calls/minute per operator, validate all phone numbers with Twilio Lookup before sending, TCPA opt-out list enforced server-side on every send.

Infrastructure Plan

Vercel for Next.js, Supabase for Postgres and auth, Twilio for SMS, GitHub Actions for CI, Sentry for error tracking, dev/staging/prod via Vercel environments.

Performance Targets

50 DAU and 500 SMS/day at launch, SMS trigger API under 2 seconds, dashboard load under 2s, Twilio delivery receipt webhook processed under 500ms.

Go-Live Checklist

☐Security audit complete
☐Payment flow tested end-to-end
☐Sentry live
☐Monitoring configured
☐Custom domain with SSL
☐Privacy policy and TCPA compliance terms published
☐5 beta operators signed off
☐Rollback plan documented
☐Facebook group launch posts drafted.

First Run Experience

On first run: a seeded demo route with 5 stops is pre-loaded showing one completed stop and a sample SMS log. User can immediately click Mark Complete on stop 2 and see the simulated SMS trigger in demo mode. No manual config required: Twilio runs in sandbox mode, demo stop data loads from seed.ts.

How to build it, step by step

1. Define schema in lib/db/schema.ts: Operator, Route, Stop, SMSLog, OptOut tables. 2. Scaffold Next.js app with Supabase Auth. 3. Build lib/twilio.ts wrapping Twilio Node SDK for outbound SMS and inbound webhook parsing. 4. Build lib/eta.ts computing ETA for next stop based on average of last 5 completed stop durations. 5. Create app/api/stops/route.ts for CRUD on stop list. 6. Create app/api/sms/send/route.ts triggering Twilio SMS when stop is marked complete. 7. Create app/api/sms/inbound/route.ts writing opt-outs to OptOut table when customer replies STOP. 8. Build app/dashboard/page.tsx with stop list table, status toggles, and SMS receipt indicators. 9. Wire Stripe checkout gating usage beyond 50 free SMS. 10. Verify: create a route with 3 stops, mark first complete, confirm SMS fires to second customer with correct ETA, reply STOP from test phone, confirm opt-out appears in dashboard.
