FAQ
Which platform do you recommend — Vapi AI or Retell AI?
Both are excellent. I recommend Vapi AI for complex workflows, multi-agent squads, and deep customization. Retell AI is better for faster setup and cleaner conversation flow. After I understand your use case and call volume, I'll recommend the right one honestly — no platform bias.
Will the AI voice agent sound robotic or natural?
It sounds genuinely human. I use ElevenLabs or Cartesia voices with tuned prompts, natural pauses, interruption handling, and filler words so the AI doesn't sound scripted. Before you order, I can send you a live demo call so you can hear it yourself.
What are my ongoing monthly costs after you deliver the setup?
No platform subscription on Vapi or Retell — both pay-as-you-go. You'll pay: Twilio number ~$1.15/mo, per-minute call cost $0.10–$0.25/min (voice + LLM + telephony), optional n8n for CRM $0–$60/mo. Typical SMB: $50–$400/mo. Estimates only; varies with call volume.
Can the AI voice agent connect to my CRM?
Yes. I integrate with GoHighLevel, HubSpot, Salesforce, Zoho, Pipedrive, Airtable, and any CRM with an API or webhook. Call transcripts, lead data, appointments, and tags sync automatically. I use n8n or Make.com to build reliable two-way data flows.
Can the AI receptionist book appointments on my calendar?
Yes. The agent checks availability on Google Calendar, Outlook, or GoHighLevel in real time, books open slots, sends SMS + email confirmation, and handles reschedules. It can also enforce buffer times, business hours, and service-specific durations.
Can the AI transfer calls to a real person when needed?
Absolutely. I set up warm-transfer logic so the AI hands off to your team for complex cases, VIP callers, billing issues, or any trigger you define. It can also send a whisper message to your agent so they know the context before picking up.
What happens if the AI voice agent breaks or stops working after delivery?
All packages include 14 days of free bug fixes after delivery. After that, I offer a monthly maintenance retainer starting at $297/month covering prompt updates, integration fixes, voice tuning, and priority support. Most clients keep me on retainer long-term.
Do I own the AI voice agent after delivery?
Yes, 100%. The Vapi or Retell account is yours, all prompts and call flows belong to you, and the n8n workflows and CRM integrations are fully transferable. I can deploy everything under your own accounts so you retain complete control.
