I’m rolling out always-on voice agents for HVAC and other home-service companies and need an engineer who can turn my concept into a production-ready platform on Vapi. The goal is a white-label solution that can take inbound calls, qualify prospects, book appointments, handle missed-call text follow-ups, and trigger outbound speed-to-lead calls—all while sounding natural in English and Spanish. Here’s what I’d like you to deliver: • Design and deploy inbound and outbound agents on Vapi or others , complete with human-sounding call flows. • Build lead-qualification logic and real-time appointment booking that syncs with Google Calendar, [login to view URL], or GoHighLevel calendars. • Create missed-call and follow-up automations that send SMS from GoHighLevel and update the client’s CRM. • Train a lightweight knowledge base for each client so the agent can answer common HVAC/service questions. • Package everything into reusable templates so new clients can be onboarded quickly without code changes. • Test, troubleshoot, and optimise for call quality, hand-off accuracy, and booking rates. I have a general idea of the desired call flow, but I’m counting on your expertise to refine it, suggest improvements, and implement best practices for bilingual support. Success means a fully automated voice system that passes test calls, books real appointments, and can be replicated across multiple client accounts with minimal setup time.

Hi — Elias here from Miami. I see you're looking to roll out voice agents for HVAC and home-service companies. This is an exciting step, but I understand the real challenge lies in ensuring these voice agents can handle varied customer interactions seamlessly. Common issues in projects like this include integrating with existing systems and ensuring the voice recognition works effectively in different environments. It can be tricky to balance functionality with user experience. My approach would start with a thorough assessment of your current setup and user needs. I’d focus on building a robust API that connects your voice agents with the necessary databases and tools. Testing in real-world conditions will be key to catching any potential issues early on. To get started, I’d like to know: What specific functionalities do you prioritize for the voice agents? Additionally, do you have a preferred technology stack or existing systems in place that we should integrate with? Looking forward to discussing this further.

I understand you need a production-ready, white-label voice receptionist platform on Vapi for home-service companies. My experience building automated call handling systems for lead generation and appointment booking, including implementing natural-sounding English and Spanish dialogue flows, directly aligns with your goal of qualifying prospects and triggering speed-to-lead calls. I successfully deployed a similar system that increased qualified leads by 25% for a previous client. I will design and deploy two core Vapi agents: one for inbound call handling, featuring dynamic scripts for prospect qualification and appointment booking, and another for outbound speed-to-lead calls. These agents will be built using Python and Vapi's SDK, integrating with a PostgreSQL database for prospect data and appointment scheduling. Missed-call text follow-ups will be managed via Twilio. The resulting platform will offer configurable scripts and agent personas to ensure a white-label feel for each client. What is the expected volume of inbound calls per day for the initial deployment? Ready to start as soon as you confirm scope.

Hi how are you doing, A white-label voice agent platform that genuinely sounds natural for HVAC companies really comes down to the core call flow and backend integrations. Building the Vapi agents, integrating with calendars like Google Calendar or GoHighLevel, and handling GoHighLevel SMS for missed calls are quite familiar tasks. The deliverables outlined are well within familiar territory, ensuring a smooth path to production for your English and Spanish speaking agents. My experience shipping products like TryReplify, which required careful integration of LLM features end-to-end, directly applies to your platform vision. A short chat can nail priorities and timeline - appreciate your time.

I’ve deployed bilingual inbound/outbound agents on Vapi before—handled call flows for lead qualification, booking, and SMS follow-ups—so this is right in my wheelhouse. I’ll set up Vapi agents with dual-language TTS/ASR, build the qualification logic in Python, sync bookings directly to Google Calendar via CalDAV, and trigger GoHighLevel SMS from missed-call events. Knowledge bases will live in Pinecone for fast retrieval, templates will be parameterized JSON for one-click client onboarding, and I’ll validate with test calls, tuning Vapi’s voice parameters and booking retry logic to hit 90%+ call completion. I can outline milestones after reviewing your call-flow spec.
