Zellbox

Zellbox is the CRM for appointment-driven businesses — one inbox, one calendar, one team. It unifies WhatsApp Business, Gmail, and Google Calendar so bookings, reminders, and customer replies all live in a single place. Automated WhatsApp reminders cut no-shows, and the whole team sees every conversation.

Zellbox brings WhatsApp Business and Google Calendar together for the businesses that live and die by their appointment book — clinics, salons, home-service trades, veterinary practices, real-estate agents, coaches, and field sales teams. Bookings, automated reminders, and every customer reply land in one unified workspace, so nothing slips through the cracks and the whole team stays in sync.

  • Unified Inbox
    WhatsApp and Gmail replies arrive in a single shared inbox — one place to read and respond, with full team visibility.
  • WhatsApp Coexistence
