How Much Does an AI Voice Agent & n8n Automation System Cost? (Setup vs. Monthly Pass-Through Guide)

How much does it cost to build and run a 24/7 AI Voice Agent?
A production 24/7 AI Voice Agent at Tiyan Digital costs $299 one-time setup plus $99/month for an Inbound AI Receptionist (Basic), $599 setup plus $199/month for Inbound + Outbound Speed-to-Lead calling (Standard), or $1,199 setup plus $349/month for Enterprise multi-agent voice infrastructure, plus ~$0.09–$0.15/minute in direct telecom/LLM usage.
When evaluating AI phone agent providers, businesses frequently encounter two traps: SaaS wrappers that charge $0.50 to $1.00 per minute (a 400%+ markup on underlying infrastructure), or custom dev shops quoting $10,000+ for basic calendar booking.
By separating our fixed engineering setup and maintenance fee from your direct provider usage, you pay the true wholesale rate for telephony (Twilio), voice orchestration (Vapi/Retell), transcription (Deepgram), and neural speech synthesis (ElevenLabs/Cartesia).
| Cost Layer | Basic (Inbound) | Standard (In + Outbound) | Premium (Enterprise) |
|---|---|---|---|
| One-Time Engineering Setup | $299 | $599 | $1,199 |
| Monthly Monitoring & Tuning | $99/mo | $199/mo | $349/mo |
| Agents Included | 1 Inbound Agent | 1 Inbound + 1 Outbound | Up to 5 Specialized Agents |
| Calendar & CRM Sync | Google Cal / Sheets | Two-Way HubSpot / GHL / CRM | Custom API Tool-Calling |
| Wholesale Per-Minute Usage | ~$0.09–$0.15/min | ~$0.09–$0.15/min | ~$0.09–$0.15/min |
How much money does n8n workflow automation save compared to Zapier?
Migrating multi-step business automations from Zapier to n8n typically reduces recurring software execution costs by 60% to 80%, because n8n executes entire multi-node workflows without charging per individual internal step, filter, or loop iteration.
At Tiyan Digital, our AI Workflow Automation tiers start at $199 setup + $59/month for 1–2 workflows (Basic), $499 setup + $149/month for 3–7 business workflows including document processing (Standard), and $999 setup + $299/month for 8–15+ workflows on dedicated self-hosted n8n infrastructure (Premium).
