AI Receptionist Platform
for Trade Businesses
Orderly Systems built TalkWize so home service businesses stop bleeding leads to missed calls. A trade owner buys online, runs through a five-step setup, and the AI is answering their phone before they make their next coffee. Every call gets transcribed and summarized to their inbox.
Overview
TalkWize serves home service businesses (HVAC, electrical, plumbing, roofing) where every missed call is a missed job. Owners cannot live on the phone, and a human receptionist is rarely worth it at their stage. Orderly Systems built the full AI receptionist platform: buyers purchase online, complete a short setup, and have an AI answering their phones within minutes. Owners get a transcript and summary of every call in their inbox.
The Challenge
TalkWize needed a platform that took a brand-new buyer from credit-card swipe to working AI receptionist with zero engineering help, while staying smart enough to handle calls the way a good human would in HVAC, electrical, plumbing, or roofing.
The system had to thread Retell's voice events with Stripe checkout, Supabase auth and data, SendGrid emails, and n8n workflows, and do it reliably enough that a trade owner with a wrench in his hand could trust it. Orderly Systems built the entire stack and the operating playbook behind it.
Our Approach
Orderly Systems delivered in four phases, validating each one before adding the next.
Phase 1: Foundation & Authentication
Established Supabase as the data layer. Implemented Stripe Checkout with webhook handling for checkout.session.completed, creating Supabase Auth users and client records, then triggering magic-link emails via SendGrid. Designed purchase-first flow with no standalone sign-up.
Phase 2: Onboarding & Agent Provisioning
Built a 5-step onboarding flow: Password Setup → Business Details → Prompt Configuration → Agent Creation → Phone Number Provisioning. Integrated Retell SDK to create LLMs with assembled prompts, create agents with configurable voice, and provision phone numbers by area code.
Phase 3: Inbound Webhook & Workflow Automation
Deployed a standalone Fastify inbound server on Render to receive Retell webhooks. Implemented call state management across call_inbound, call_started, call_ended, and call_analyzed events. Built n8n workflows for conversation storage and email notifications.
Phase 4: Dashboard & Settings
Built Next.js 15 + React 19 dashboard with Tailwind and Radix UI. Implemented receptionist status page with real-time analytics, conversation history with transcripts, and settings page with editable prompt sections. Ensured prompt updates propagate to Retell LLM via API.

Outcomes
Round-the-clock call answering, no after-hours missed leads
Missed calls when the AI receptionist is configured
Transcripts and summaries for every conversation
Email alerts so owners never miss an appointment request
TalkWize now has the knowledge layer for what a good receptionist does, captured once and reused for every business that signs up. Calls get answered around the clock. Transcripts and summaries land in the owner's inbox. The system can scale to thousands of customers without adding people, and as the team adds new industries, calendars, or call transfers, the foundation holds.
