AI Voice Agents
AI voice agents that answer every call for local service businesses.
If you run a plumbing, HVAC, solar, or other home-service business, a missed call is a missed job. We build AI voice agents on Vapi and SignalWire that pick up in under a second, qualify leads, book appointments straight to your calendar, and drop every call into your CRM — while you're on a job, asleep, or just have your hands full.
Sales On Demand builds AI voice agents for small businesses — an AI phone answering service that picks up inbound calls in under a second, runs automated lead-qualification calls (and outbound reactivation), books appointments straight to your calendar, and writes every call into your CRM. Built on Vapi and SignalWire, wired into GoHighLevel, available in English and Spanish.
How much does an AI voice agent cost?
You pay the platforms (Vapi, ~$0.05–0.15/min; SignalWire voice on top) directly at cost — a typical inbound agent handling 200 calls/month runs roughly $50–150/mo in usage. Our fee covers the build, configuration, and ongoing management. Full breakdown: how much an AI voice agent costs.
How does an AI voice agent qualify leads?
The agent runs a custom script — name, contact info, service need, timeline, budget — scores the lead, then either books the appointment live or routes the contact to your team with a note. See how an AI voice agent qualifies leads and why speed to lead is the whole point — Harvard Business Review's research on lead response time found firms that contact a lead within an hour are far likelier to qualify it.
Is an AI voice agent better than hiring an SDR or call center?
It depends on volume and the work. An agent doesn't sleep, doesn't churn, and costs a fraction of a salary — but a human still closes complex deals better. We help you draw that line: AI voice agent vs hiring an SDR and AI voice agent vs a call center.
Will an AI receptionist annoy my customers?
Done badly, yes. Done well, callers usually can't tell — and they'd rather talk to a competent agent now than a voicemail. We tune voice, cadence, and escalation per client: will an AI receptionist annoy my customers. On outbound, the FTC's Do Not Call rules and the TCPA govern automated calls — we build opt-out handling and disclosure into every outbound agent, and require clients to confirm their lists are compliant.
Use cases
Four things agents do that your team can't.
Namely: answer every call at 11pm, dial 300 old leads before 9am, and never take a sick day.
Inbound lead qualification
Every inbound call is answered in under a second. The agent collects name, contact info, service need, timeline, and budget — then routes based on qualification score or books directly to your calendar. No more leads lost to voicemail.
Outbound reactivation
Got a list of old leads that went cold? We build agents that dial them systematically, introduce your offer, and warm them back up for a human follow-up. Works for any business with a lead list that's gone quiet.
Appointment booking + reminders
The agent books to your GHL calendar in real time during the call — no transfer, no callback, no "we'll send you a link." Pre-appointment reminder calls are automated on the same system.
After-hours coverage
Most local service businesses lose leads between 6pm and 9am. An after-hours agent handles those calls exactly like a daytime agent: qualify, book, CRM — with a note flagging it as after-hours so your team has context in the morning.
The stack
Purpose-built voice infrastructure.
LLM orchestration, TTS/STT, conversation management
Best-in-class latency for conversational voice. Sub-1s response times.
Voice infrastructure, phone number management, PSTN routing
Carrier-grade reliability. We use it where Twilio-based infrastructure adds cost or latency.
CRM, calendar, contact management, pipeline routing
Every call outcome writes directly to GHL — contact created, pipeline stage set, appointment booked.
Real-time routing, escalation triggers, team notifications
When the agent flags a call for escalation or a hot lead, your team knows in seconds via SMS or Slack.
Live deployments
11 agents live for clients across industries.
We've deployed 11 agents for clients across industries — each custom-trained on their business, not a template. Same infrastructure, completely different configuration for every client.
Every agent is built from scratch: the questions it asks, the objections it handles, how it routes qualified vs. unqualified leads, and the CRM workflows it triggers. They share infrastructure but nothing else.
What each agent covers
- Custom qualification script for your specific offer
- Inbound + outbound configurations available
- Direct calendar booking during the call
- CRM contact creation + pipeline routing
- Escalation triggers for hot leads or upset callers
- After-hours coverage, same as daytime
Bilingual
English and Spanish. Built in, not bolted on.
We build bilingual agents that detect language from the caller's first sentence and respond in kind — no menu prompt, no "press 2 for Spanish." The conversation flows in the language the caller is most comfortable in.
Spanish-language support isn't an add-on. It's standard configuration for any client serving a bilingual market. If your customers speak Spanish and you're not serving them in it, you're losing business to someone who is.
