Is the $0.25/minute AI cost realistic?

Yes. That's Smarfle's pay-as-you-go rate for Voice AI minutes (no monthly minimum). A typical 3-minute call costs $0.75. 200 calls a month at 3 min average = $150.

What about the phone number?

Smarfle includes a $5/month phone number provisioned via Twilio (or you can forward your existing number). The number cost is separate from per-minute usage.

Does the AI sound natural?

It uses Amazon Polly neural voices (11 voice options, all sound human). The conversation is powered by Claude AI with full context of your services, calendar, and business hours: it knows what you charge, what you do, and when you're available.

Can it actually book jobs?

Yes. It reads your calendar, asks for the customer's preferred time, and creates a work order in Smarfle automatically. You get a notification and can approve before the slot is locked.

What if it can't handle the call?

You set a transfer number (your cell, an office line, etc.). The AI escalates anything outside its scope (emergency calls, complex quotes, complaints) instead of guessing.

How this calculation works

Three numbers drive the result: 1. Recovered jobs: missed calls × booking rate. These are jobs you'd capture once calls get answered 24/7. 2. Recovered revenue: those jobs × your average ticket. 3. Cost savings: if you're paying a receptionist or answering service, subtract the AI cost from that line item too. Net benefit = recovered revenue + cost savings. Payback period is how many days into the month the recovered revenue covers the AI cost. ROI is monthly net benefit ÷ AI cost. Default assumes 200 calls/month, 35% missed (typical for owner-operated service businesses), 50% booking rate on answered calls, $350 average job, and $150/month AI usage (200 calls × ~3 min avg × $0.25/min).

HVAC shop with 4 techs

300 calls/month, 35% missed, was paying an answering service $400/mo.

AI costs ~$225/mo (less than the answering service it replaced) and recovers ~25 jobs/month at $450 each. Net annual benefit: ~$135K.

Solo plumber, 24/7 emergency

250 calls/month, 40% missed (mostly nights/weekends), no current coverage.

After-hours emergency tickets average $700+. AI handles them, books the morning slot, and texts the on-call tech. Payback in under 2 days.

Owner replacing front-desk hire

Part-time receptionist costs $3,500/mo and doesn't cover nights or weekends.

AI is $300/mo, runs 24/7, and never calls in sick. Direct savings of ~$38K/year before recovered jobs.
