AI Voice Agents for Trade Contractors: Avoca, 11x, and Beyond

Avoca raised $125M at a $1B valuation in April 2026. That number told the contracting industry something it already suspected: AI voice agents for trade contractors are no longer experimental. They are the new front office.

But Avoca is one option. 11x, Goodcall, Hatch, and a half-dozen smaller players are all in the same fight. If you run a $10M HVAC shop, an electrical contracting business, or a multi-trade operation, the question isn't whether to add an AI voice agent. It's which one — and whether your current CSR team gets layered with one or partially replaced by one.

Here's the honest landscape as of mid-2026.

What an AI voice agent actually does

For a trade contractor, an AI voice agent handles three things: inbound call answering (especially after hours), appointment booking against your dispatch calendar, and follow-up on quotes that haven't closed. The good ones integrate directly with ServiceTitan, FieldEdge, or Workiz so the booked appointment appears in your dispatch board the same way a CSR-booked appointment would.

The bad ones are glorified IVR systems with a synthetic voice. The difference is whether the agent understands when to escalate to a human and whether it can hold a multi-turn conversation about availability.

The 2026 vendor landscape

Vendor	Best for	Monthly cost	Integrations
Avoca	HVAC / plumbing / electrical 10-100 techs	$1,500-$4,000	ServiceTitan, FieldEdge
11x (Alice)	Outbound + inbound	$2,000-$5,000	CRM-agnostic via Zapier
Goodcall	1-10 tech shops	$59-$299	HubSpot, Google Calendar
Hatch	SMS-first lead nurture	$600-$1,800	ServiceTitan, Jobber
Numa	Multi-location dealerships + service	$400-$1,200	Twilio-based, custom

Avoca: the category leader

Avoca built specifically for HVAC, plumbing, and electrical. The ServiceTitan integration is the deepest in the category. Their AI agent can quote diagnostic fees by service area, route emergencies to your on-call tech, and book maintenance plans without human handoff.

The reasons contractors pick Avoca: deepest vertical knowledge, mature integrations, and the founders genuinely understand contractor ops. The reasons they don't: pricing is gated on the high end (often $2K+/month for a 10-tech shop), and the contract structure isn't built for shops with under 5 techs.

11x: the outbound-first challenger

11x got famous for AI SDR "Alice," an outbound agent built for B2B sales. They have since extended into inbound for service businesses. The pitch: one agent that does both inbound answering and outbound nurture of unconverted leads.

The trade-off: 11x is less vertical-specific than Avoca. You spend more time configuring it for HVAC-specific workflows. For shops that already have strong inbound CSR coverage but bleed money on outbound lead nurture, 11x is the sharper pick.

Goodcall: the small shop pick

Goodcall charges $59-$299/month and is the right starting point for shops doing under $3M revenue. Two or three techs, an owner who answers the phone half the time, and no dedicated CSR. Goodcall answers, books, and texts a calendar invite. The integration depth is shallow but the price is honest.

The day you cross 5 techs, you outgrow Goodcall. The day you hit 10, you should be on Avoca or comparable.

Hatch: the SMS specialist

Hatch isn't a voice agent in the traditional sense. It's an AI-powered SMS lead nurture system that converts inbound text inquiries into booked appointments. For shops where 40%+ of inbound leads come via web form or text, Hatch outperforms voice-first vendors because it meets customers where they already are.

A common pattern: Avoca for voice + Hatch for SMS. Two vendors, $2-3K/month combined, full coverage.

What none of them do well (yet)

AI voice agents are excellent at booking. They are mediocre at upsell. They are weak at handling angry repeat customers. And none of them — Avoca included — replace a senior CSR who knows your top 50 customers by name.

The right mental model: AI voice agents catch the calls your team would otherwise miss. They are not a CSR replacement; they are a CSR multiplier. Per Avoca's own customer data, the median deployment recovers 40-55% of after-hours missed-call revenue inside 60 days. That number is real, and it's also the ceiling.

The honest decision framework

Three questions decide which vendor fits:

Under 5 techs? Goodcall. Don't overspend.
5-50 techs, ServiceTitan / FieldEdge? Avoca. The vertical depth pays for itself.
50+ techs, multi-location? Avoca + custom integration work, OR Twilio + a custom build. At that scale the vendor pricing breaks down and an in-house option becomes viable.

Where this fits in your AI rollout

An AI voice agent is usually workflow #1 in a broader rollout — it has the fastest payback and the cleanest ROI math. Once it's running, you layer in AI lead routing and AI ops monitoring. Our 7-step AI implementation playbook walks through the full sequence.

And if you're tempted to skip the voice agent and just use ChatGPT to handle calls, read why "just use ChatGPT" doesn't work. The integration gap is the gap, not the language model.

Bottom line

Avoca for the median HVAC / electrical shop. Goodcall for the small shop. Hatch for SMS-heavy lead flow. 11x for outbound emphasis. And the right answer is almost never "wait six months and see" — every month you delay is another $25-50K of missed-call revenue that doesn't come back.
