How to Build an Appointment Conflict Detector

Two customers booked with the same stylist at the same time is an easy mistake in a shared sheet. A rule can flag it the moment it happens.

1. Create Staff and Appointments, and link each appointment to one staff member.
2. Give appointments a Start and an End time.
3. Add a rule: "Conflict if this staff member has another appointment that overlaps".
4. Create a view filtered to conflicts and pin it for your front desk.
