What we built
AI voice support and booking assistantA voice assistant that answers calls, works out what the caller needs, books appointments, updates customer records and hands complex calls to staff with a summary.

The challenge

What was getting
in the way

The business took a steady flow of calls about services, availability, pricing, appointment changes and basic support. Staff could not always answer every call, especially at busy times or outside office hours.

The company wanted callers to get a quick, natural response, while keeping people in charge of sensitive or complex conversations.

  • Missed calls

    Potential customers sometimes reached voicemail or had to call back.

  • Repeated questions

    Staff answered the same scheduling and service questions all day.

  • Slow follow-up

    Call details still had to be written down and typed into internal systems.

The solution
