Why Contractors Are Switching
- Stop paying $9.75 per extra call — at 100 calls/month, Smith.ai costs $780/mo vs Mercvox at $79/mo.
- Get instant pickup (<1 second) instead of waiting 4+ rings while your customer considers calling a competitor.
- Emergency detection catches "burst pipe" and "gas leak" instantly — Smith.ai generic scripts miss urgency cues.
- All features included at $79/mo — Smith.ai locks booking behind the $292/mo hybrid plan.
- Purpose-built for trades — Smith.ai serves lawyers, realtors, and SaaS companies with the same generic approach.
Smith.ai Doesn't Understand Trades
- Smith.ai uses the same scripts for a law firm and a plumbing company — Mercvox asks trade-specific intake questions (job type, access details, urgency).
- No emergency detection means a "gas leak" call gets the same treatment as a "schedule a tune-up" call.
- Smith.ai can't classify jobs (repair vs. install vs. maintenance) or route based on trade-specific urgency levels.
- At 100 calls/month (normal for a busy contractor), Smith.ai costs $780/mo. Mercvox costs $79/mo with better results.
Frequently Asked Questions
Is Smith.ai better because it has human operators?
Smith.ai's AI-only tier ($97.50/mo) has no humans. Their hybrid tier ($292.50/mo) adds humans but still uses generic scripts. Mercvox's trade-trained AI outperforms generic human operators for contractor calls because it understands the industry — at a fraction of the cost.
Smith.ai has been around longer — isn't that safer?
Smith.ai has been around longer because they started with live receptionists for lawyers. Their AI offering is newer and generic. Mercvox was built from the ground up specifically for trade contractors — every feature is designed for how plumbers, HVAC techs, and electricians actually work.
How does Mercvox compare at high call volumes?
Mercvox Growth plan handles unlimited calls for $149. On Smith.ai, 200 calls would cost $97.50 base + (170 × $9.75) = $1,755/month. That's 16x more expensive for the same call volume.
Does Smith.ai integrate with my scheduling software?
Smith.ai integrates with general calendars (Google, Calendly). Mercvox integrates with contractor-specific tools and books with job details pre-filled — service type, urgency, access instructions, and customer information.
Can I try Mercvox before canceling Smith.ai?
Yes. Set up Mercvox in 5 minutes and forward calls to test it. Run both services in parallel until you're confident. No contracts, cancel anytime. Most contractors switch fully within the first week.
