Manual queue handling via chat or notebooks causes duplicate bookings, slow responses, and low visibility.

A LINE-integrated queue system lets customers book instantly while staff manages all queues in one dashboard.

Customer side: ask available slots on LINE and book via LIFF.

Business side: manage branches, services, working hours, and queue statuses.

Barbers, clinics, restaurants, service centers, and appointment-heavy teams.

Supports both fixed slot and flexible duration queue models.
