A message-taking service at $4 a call looks cheap next to a flat plan, until you notice the callback still has to happen and roughly half of after-hours callers have already booked somewhere else by morning.
- Divide monthly cost by appointments actually booked, not calls answered.
- Count after-hours separately — that is where the difference between message and booking shows up.
- Include the staff minutes spent processing message slips the next morning.
