Section 01

The Problem

Missed calls, lost bookings

Calls land while staff are with clients, so new enquiries go to voicemail and never come back.

Manual scheduling

Availability is checked by hand across staff, services and time slots — slow and easy to double-book.

Repetitive questions

The same pricing, timing and service questions are answered dozens of times every week.

Disconnected customer data

Confirmations, reminders and client history live in separate places, so follow-ups get forgotten.
