What missed calls actually cost a service business (real numbers)
Most owners think a missed call costs nothing. The math says it costs $480.

The cost of a single missed call
For a dental practice with $250 average new-patient value:
- 7% of new-patient calls go to voicemail.
- 81% of voicemail-receiving callers don't leave a message.
- Of those, 53% try a competitor next.
That's 0.07 × 0.81 × 0.53 = 3% of all inbound calls lost — every one worth $250 LTV.
Run that across 600 calls/month and you're losing $4,500/month to a phone you can't pick up.
Why phones still beat forms
Older clients (45+) and emergency cases default to calling. They're also your highest-LTV demographic. Losing those is expensive.
The fix
Forward unanswered calls to a text number. Most callers will text instead — and an AI can answer those texts in under 15 seconds, 24/7. Here's how ChatBooker does it.
