Why Contractors Are Switching
- Rosie's $49/mo Starter plan can't book appointments — it just takes messages. For a contractor, that means you STILL have to call everyone back.
- To get calendar booking on Rosie, you need the $199/mo Scale plan. Mercvox includes booking on the $79/mo Starter plan.
- Rosie charges $2/call overage. A busy contractor doing 80 calls/month on Rosie Starter = $49 + (55 × $2) = $159/month with no booking.
- Rosie has zero trade-specific intelligence — no emergency detection, no job classification, no urgency-based routing.
- Mercvox asks the intake questions that matter to contractors: service type, urgency level, property access, preferred scheduling.
Rosie Was Built for Generic Small Businesses — Not Trades
- Rosie handles calls for salons, dentists, and restaurants the same way it handles contractor calls — with basic name-and-number scripts.
- No emergency detection means a "flooding basement" call gets the same priority as a "schedule maintenance" call.
- Rosie can't ask about job specifics (residential vs. commercial, access instructions, number of fixtures, system age).
- Trade businesses need instant booking to capture time-sensitive leads — Rosie locks this behind a 4x more expensive plan.
Frequently Asked Questions
Rosie is cheaper at $49/month — isn't that better?
Rosie's $49/mo plan only handles 25 calls and CAN'T book appointments or transfer calls. It just takes messages. To get booking (essential for contractors), you need Rosie's $199/mo Scale plan. Mercvox includes everything at $79/mo — booking, transfers, emergency detection, and unlimited calls.
Does Rosie work for plumbers/HVAC/electricians?
Rosie works for any business in the sense that it can answer calls. But it has no trade-specific knowledge — it can't detect emergencies, classify job types, ask about system details, or prioritize based on urgency. It treats a gas leak the same as a thermostat question.
What if I only get 25 calls per month?
Even at low volume, you need booking capability to convert callers into jobs. Rosie's $49 plan takes messages only — you still call everyone back. Mercvox's $79 plan books appointments directly. That 1 auto-booked job that would have slipped away pays for months of service.
Can Rosie detect emergency calls?
No. Rosie has no emergency detection or priority routing. All calls are treated equally. For trades businesses where 25-35% of calls involve safety issues or urgent repairs, this is a critical gap. A missed emergency means lost revenue AND potential liability.
How does call quality compare?
Both use modern AI voices. The difference is in intelligence: Mercvox understands trade context ("my water heater is making a banging noise" → water heater repair, moderate urgency, schedule within 48 hours) while Rosie just records the message verbatim.
