From 55% missed calls to ~0%.
Bonnie&Car, a French online marketplace for used cars, saw more than half of its inbound calls go unanswered. Its CallShift voice agent now picks up every call, qualifies half of them on its own and keeps the line open longer, with no extra staff.

Where they started.
Bonnie&Car sells used cars online, from its store in Paris. With a small team, more than 55% of inbound calls went unanswered: missed business and unhappy customers.
Hiring more people or outsourcing was expensive and hard to scale. They chose a voice agent that takes the overflow, qualifies the caller and books the follow-up.

The AI takes the overflow
When no one on the team is free, the call goes to the voice agent, in real time.
It qualifies the caller
Preset questions: half of the callers qualified with no one involved.
It books the follow-up
A meeting in Bonnie&Car's Google Calendar, confirmed by email and SMS to the caller and to the agent.
From the people who run it.
“We went from 55% missed calls down to basically 0%. We turned around data and concluded the impact was +15% revenue last month thanks to CallShift.ai.”
Jean-Charles RoyCEO, Bonnie&Car“The quality of the discussion during scheduled calls is really impressive compared to unscheduled calls.”
“CallShift.ai had a significant impact on the efficiency of our customer relations, which naturally reflected in the number of sales.”

- Calls go unanswered at peak times or after hours.
