Why Contractors Are Switching
- Ruby bills by the minute. A busy contractor with 80 calls averaging 3 minutes needs 240 minutes — more than Ruby's $720/mo 200-minute plan. Mercvox covers 80 calls for $89/mo.
- Long emergency calls cost more on per-minute billing. A 5-minute call on Ruby's 100-minute plan uses about $20 of your allowance. On Mercvox, it's one call.
- Mercvox is trained on trade calls — it knows the difference between a routine tune-up and a gas smell that needs immediate dispatch.
- Setup takes about 10 minutes with pre-built templates for plumbing, HVAC, and electrical services.
- No contracts and a 14-day free trial, so you can test it alongside Ruby before switching.
Why Per-Minute Billing Hurts Contractors
- Trade calls take time: describing the problem, checking urgency, confirming access. Per-minute billing makes thorough intake expensive.
- Call volume spikes during storms, heat waves, and cold snaps. A minute-based plan can run out in a single busy week.
- Ruby's receptionists serve many industries. Mercvox is built around trade terminology, job types, and emergency triage.
- Mercvox handles unlimited simultaneous calls, so a burst of storm calls never means callers waiting in a queue.
Frequently Asked Questions
Isn't a human receptionist better for customer experience?
Ruby's receptionists are known for friendly service, and some businesses value that above all else. For trade service calls, speed and getting the job booked matter most. Mercvox picks up in under a second, understands the urgency, and books the job — and can transfer to you whenever a caller wants a person.
Ruby has excellent reviews — why switch?
Ruby is a good fit for businesses that want a human voice on every call and are comfortable with per-minute pricing. Contractors with high call volume, long intake calls, and frequent emergencies usually get more value from Mercvox's flat pricing and trade-specific intake.
What if a customer specifically wants to talk to a human?
Mercvox can transfer to you or your team anytime. You set the rules — for example, always transfer emergencies or when the caller asks for the owner.
How do Ruby's per-minute costs add up for a busy contractor?
A contractor averaging 80 calls/month at 3 minutes each uses 240 minutes. That is more than Ruby's 200-minute plan ($720/mo), so you would need overage minutes or the 500-minute plan ($1,725/mo). On Mercvox, 80 calls costs $89/month (Starter plus 10 extra calls).
Does Ruby answer after hours?
Yes. Ruby now offers 24/7 live answering, including weekends and holidays. The main differences are cost (per-minute billing vs flat monthly) and trade-specific intelligence.
