A worked example, not a forecast
Smith.ai's Basic plan is $810 for 90 calls, about $9 for each included call. VoiceBridg is $25 for each booked job. Dividing one by the other, $9 ÷ $25, gives about 36%.
So on those two prices alone, a per-call plan costs less when more than about 36 in every 100 calls end as booked jobs, and booked-job pricing costs less when fewer do. Calls that never become jobs, such as wrong numbers, spam and questions, are where the difference comes from.
The two buy different things. A call plan pays for every call answered. Booked-job pricing pays only when a job lands on your schedule. Use your own call log to find your share.
Where Smith.ai may fit better
- You want a fixed monthly bill that doesn't change with how many jobs book.
- You want people answering every call, which its page describes as live-staffed agents 24/7.
- You want agents based only in the US. Its page states no overseas agents.
Where VoiceBridg may fit better
- You want to pay only when a call ends with a job on your schedule.
- You want AI to answer in one ring and a trained human desk to take over the same call when a caller needs a person.
- You want a gas or carbon monoxide call to follow a safety script instead of being booked.
- You get Spanish-speaking callers.
How to compare any two providers fairly
- Count your calls for a month, and how many ended as booked jobs.
- Ask what a provider charges for calls that don't book.
- Ask how a booked job reaches your schedule today, not later.
- Ask what happens with an emergency, a gas smell, and a caller who asks for a person.
- Check the date on any price you are given.
